Art Ditmar

This article was written by David E. Skelton

In 1955 the Kansas City Athletics coaching staff “observed [rookie right-hander Art] Ditmar during spring training and prophesied that he was destined for distinction on the mound.”1 This bright assessment was echoed three years later by New York Yankees manager Casey Stengel, who said, “I believe … Ditmar could grow into one of the big pitchers in the majors. … [T]he first thing he must develop is the realization that he is as good as he is, and that he has so much in him.”2 This latter appraisal seemingly explains the Old Perfessor’s decision to start Ditmar in Game One of the 1960 World Series. Though his choice has been roundly condemned by armchair managers through the years, the decision did little to remove the label of invincibility that once surrounded the hard-throwing hurler.

Arthur John Ditmar was born on April 3, 1929, the second of three children of George Edward and Caroline Dorothy (Huysman) Ditmar, in the Boston suburb of Winthrop, Massachusetts. He was the great-grandson of German immigrant Henry V. Ditmar, who arrived in the Bay State in the first half of the nineteenth century. In 1855 Henry married Isabella Logan, an Irish immigrant, and they raised six children to adulthood. Their youngest son, Francis “Frank” Ditmar, pursued a career as a house painter in Boston and in 1891 married Massachusetts native Mary Canavan. This union produced five children, the youngest of whom was Art’s father, George. In the 1920s George launched a career in sales and married Caroline. After the birth of their children the family moved to the other end of the state, settling in Pittsfield, Massachusetts.

The children attended Pittsfield High School, which has produced a large list of accomplished alumni including actress Elizabeth Banks and All-Star shortstop Mark Belanger. Art and his elder brother George established their own credentials at Pittsfield High on both the hardwood court and diamond field.3 Though he played some outfield, Art was primarily a pitcher. He posted a 14-2 record for the Pittsfield Generals and was captain of the baseball team his senior year. (He also excelled in American Legion baseball but was discouraged from playing football for fear of injuring his arm.) In 1947 scouts from the St. Louis Cardinals, Pittsburgh Pirates, and Philadelphia Athletics swarmed after Ditmar pitched a one-hit gem during a tournament in Johnstown, Pennsylvania. He was invited to Philadelphia’s Shibe Park for a tryout under the watchful eye of Athletics skipper Connie Mack. After graduating from high school in 1947, Ditmar spurned an athletic scholarship to the University of Mississippi to sign a $1,000 bonus contract with Athletics scout and former minor-league hurler Richard “Lefty” Lloyd.4

In 1948 Ditmar was assigned to the Moline/Kewanee (Illinois) A’s in the Central Association (Class C). Among the most durable pitchers in the league, the 19-year-old placed among the league leaders in appearances (33) and innings pitched (193). This was accompanied by a large yield in walks (108) that contributed to a pedestrian record of 9-9, 3.68. The next year Ditmar was promoted to the Savannah Indians in the South Atlantic League (Class A). Initially projected as a starter, he was moved to the bullpen after right-hander Harry Byrd, who was expected to compete in the majors, failed in spring training and was assigned to the Indians. Ditmar made occasional starts and on June 16, 1949, he delivered a four-hit shutout against the Charleston Rebels. More importantly, he lowered his walk ratio by nearly 30 percent to finish with a record of 7-6, 2.85 in 142 innings. The Rebels fell victim again the following season when Ditmar tossed another shutout on April 24, 1950, while surrendering just one hit. The win was the first of his minor-league career-high 13 as he anchored the Indians staff alongside fellow right-handers Duke Simpson and Kelly Swift. But Ditmar was unable to build upon this success by 1953, when he was drafted into the US Army during the Korean War. He did not see combat and spent a portion of his service at Camp Atterbury, Indiana, where his teammates included future major-league hurlers Frank Lary and Tom Brewer.

On April 26, 1953, Ditmar made his return among the professional ranks with the Ottawa A’s in the Triple-A International League. It did not go swimmingly. With the exception of a four-hit shutout against the Toronto Maple Leafs in May, he struggled with his control through most of the season en route to a record of 2-13, 5.30. Optioned to Savannah in July, Ditmar rebounded with a perfect 7-0 posting that included a three-hit shutout of the Augusta Rams.5 The abrupt turnaround captured the imagination of the pitching-poor Philadelphia Athletics and Ditmar was selected among the September call-ups though he did not make an appearance. During the offseason Ditmar was added to the club’s 40-man roster.

The following spring Ditmar competed with three others for the club’s fifth-starter role. Though he fell short in this competition, his strong Grapefruit League campaign earned the 25-year-old a spot on the parent roster. On April 19, 1954, Ditmar made his major-league debut in Washington’s Griffith Stadium in relief of lefty starter Morrie Martin. Entering in the sixth inning against the Senators tasked with protecting a 3-1 lead, Ditmar walked the first batter he faced, slugger Roy Sievers, before retiring the side. Far less success ensued in the seventh when a throwing error by A’s first baseman Don Bollweg led to two unearned runs. The game remained tied into the ninth when Ditmar surrender a walk-off homer to leadoff hitter Eddie Yost.

After a dismal appearance on May 3 against the Chicago White Sox – a game in which few Philadelphia pitchers shone in a 14-3 blowout – Ditmar pitched eight strong innings of relief over three appearances to earn his first major-league start. Facing the Senators on May 21, he was lifted after the first inning after surrendering five hits and two walks to the first eight batters. A similar fate awaited Ditmar in Boston 10 days later when a three-run homer by Ted Williams in the first and a bases-loaded walk in the second made for a very short outing. On June 12 Ditmar was optioned to Ottawa. Though he struggled with a sore arm in Ottawa, his 6-12 record was deceptive as he received little run support from the offensively inept last-place club.

Recalled by the Athletics in September, Ditmar drew a September 19 start at home against the Yankees. Following a leadoff single by second baseman Gil McDougald he held the Bombers hitless through 4⅔ innings before wriggling out of a bases-loaded jam in the fifth. He did not figure in the decision. Ditmar got a second start a week later in Yankee Stadium. In the meaningless season finale, Stengel fielded a unique lineup with center fielder Mickey Mantle at short and catcher Yogi Berra at third. The future Hall of Famers handled their posts flawlessly as the Yankees captured a slim 3-2 lead through four innings before the A’s offense – a generally ineffective lot throughout the season – opened for three runs in the fifth. Though lifted after 5⅔ innings, Ditmar earned his first major-league win while also collecting the last victory for the Athletics as a Philadelphia-based club.

Ditmar’s sparkling 1955 debut in Kansas City (four innings of two-hit relief against the White Sox on April 22) combined with less-than-promising April outings from righty Arnie Portocarrero prompted Ditmar’s slide into the Athletics rotation. In his first start, against the Senators on May 1, he gave up five runs in the first inning and was yanked before the Athletics took a commanding lead. He quickly rebounded and over the next 19 days began “to justify [his] prospective star rating”6 with strong back-to-back outings in Boston and Chicago. The latter performance was particularly rewarding as Ditmar held the White Sox to just one hit through 8⅔ innings and earned his first career shutout. Though he encountered difficulties throughout the season – a 9.62 ERA in his team-leading 12 losses7 — Ditmar won four of his last five decisions to finish with the club lead in wins (12), complete games (7), innings (175⅓), and strikeouts (79). “I can thank several people for this,” Ditmar said. “One in particular is [coach] George Susce, who helped me with the sinker ball. It has become my best pitch.”8 During the offseason the club spurned an aggressive attempt by the White Sox to acquire Ditmar in a multiplayer swap while Athletics manager Lou Boudreau expressed his opinion that Ditmar would “be a fixture for the next seven or eight years.”9 

Except for a strong performance against the Detroit Tigers on March 27 – a two-hit gem he shared with veteran righty Lou Kretlow – Ditmar struggled through much of Athletics’ 1956 spring training. Despite the setbacks he was tabbed in a poll of nationwide scribes as the most likely Kansas City hurler to win 20 games in 1956; as it turned out, they had the number in the wrong column. Initially Ditmar appeared poised to prove the scribes correct when he tossed a one-hitter against the White Sox on April 21 in a 15-1 blowout. (A decent hitter, Ditmar collected two hits, one of which came when the Athletics scored a then-major league record 13 runs in the second inning, all the runs scoring with two outs). Less than three weeks later he collected his second career shutout by scattering seven hits against the Orioles in Baltimore. Yankees assistant GM Bill DeWitt ranked Ditmar among the AL’s best flamethrowers and the interest from New York only intensified after the righty tossed another shutout on May 27 against the Tigers.

But Ditmar’s season turned on a 7-2 loss to the Orioles on June 17, the first of four consecutive defeats. A month later he began a dismal string by losing 11 straight starts including two heartbreaking losses to Washington and Cleveland during which he surrendered only two earned runs in 18⅓ innings. In nearly one-third of his season-long 34 starts, the Athletics’ anemic offense scored less than two runs. Ditmar posted a record of 6-17, 5.09 over his last 30 appearances en route to a major-league worst 22 losses. He led the AL with 125 earned runs yielded. Despite these homely numbers, Ditmar continued to draw considerable interest from major-league clubs throughout the offseason, including particularly aggressive pursuits from the Boston Red Sox and Cleveland Indians. On February 19, 1957, over the objections of Boudreau, he was sent to the Yankees with former AL MVP left-hander Bobby Shantz in a multiplayer swap. “Ditmar is the ace of the deal as far as we are concerned,” said Yankees GM George Weiss, who had a history of success turning around former 20-game losers Fred Sanford and Don Larsen.10 A dismayed Ted Williams predicted a 20-win season for Ditmar while Indians GM Hank Greenberg bitterly declared, “It must be nice to have a farm club in your own league.”11

But the Splendid Splinter’s 20-win prediction was not in store for Ditmar. In his first three starts in the 1957 season, Ditmar surrendered 27 hits and 9 runs over 15⅓ innings that prompted Joe King to write in The Sporting News, “[He’s] as easy to hit as a Class D rookie with a straight ball.”12 Far more success was found working from the bullpen, where Ditmar posted a 6-1, 1.75 ERA record in 35 relief appearances. He continued to earn occasional starts throughout the season, including a 4-3 win against the White Sox on June 13 in which a wild pitch sent Chicago’s Larry Doby sprawling and precipitated a 28-minute bench-clearing rhubarb. Ditmar was fined $100 for the errant throw. 

Beginning at the season’s one-quarter mark, the Yankees initiated a 75-38 run to easily capture their 23rd AL flag, providing Ditmar with his first postseason experience. On October 3 he entered the fourth inning of Game Two of the World Series against the Milwaukee Braves trailing 4-2 with no outs and a runner on third and induced two infield popups and a grounder to short to stem the bleeding. Before being lifted in the seventh for a pinch-hitter, he surrendered just a bunt single over four innings to keep the Yankees close in an eventual 4-2 loss. A week later Ditmar added to his scoreless string with two innings of one-hit pitching in Game Seven. When the Series ended in seven-game defeat, he was the only Yankees pitcher to go unscored upon (more than one inning) in the fall classic.

In 1958 Ditmar extended his World Series scoreless string another 3⅔ innings after narrowly dodging a return to Kansas City. Having started the season in the bullpen, Ditmar was initially packaged alongside veteran outfielder Harry Simpson in a June 15 trade for A’s pitchers Duke Maas and Virgil Trucks until, at the last minute, the parties agreed upon righty Bob Grim instead. (This was after Ditmar chipped in with teammates Mickey Mantle, Don Larsen, Tom Sturdivant, and Jerry Lumpe to purchase an eight-year-old sedan to carpool from their New Jersey homes to Yankee Stadium.) Ditmar was moved into the Yankees rotation to spell injury-plagued righty Tom Sturdivant. On July 23 he carried a three-hit shutout into the ninth against the Tigers before a string of singles forced him to settle for a 16-4 win. Two complete game wins in August lifted Ditmar’s record to 8-2, 2.50 before he was moved back to the bullpen following a 1-5 slide. On September 14 Ditmar secured the final out in the pennant-clinching 5-3 win over the Athletics. He finished with a record of 9-8, 3.42 in 139⅔ innings.

On October 8 Ditmar appeared in Game Six of the 1958 World Series in relief of a struggling Whitey Ford. Entering the second against Milwaukee trailing 2-1 with one out and the bases loaded, Ditmar induced perennial All-Star shortstop Johnny Logan to fly out to left on the first pitch. When Andy Pafko attempted to tag up, left fielder Elston Howard threw a strike to catcher Yogi Berra to end the inning. Ditmar held the Braves to two hits over the next three innings before being lifted for a pinch-hitter in an eventual 4-3 Yankees win. The next day he earned his only championship ring when New York outlasted Milwaukee in Game Seven.

During the offseason the Yankees turned away numerous offers for Ditmar. This decision proved prescient when the righty, in the wake of reigning Cy Young Award winner Bob Turley’s 1959 struggles, became one of the staples in the Yankees rotation. “[The sportswriters] don’t say much about this Ditmar,” Stengel said. “[B]ut he is one pitcher who never says my arm is no good. … he is a manager’s kind of ball player.”13 With the exception of a fifth-inning homer by Rocky Colavito on May 1, Ditmar threw seven innings of perfect baseball in an eventual 4-2 loss to the Indians.14 Six weeks later he surrendered a first-inning run before shutting down the White Sox on two hits in a 5-1 complete-game win. But his finest performance of the season came on August 28 when Ditmar delivered a two-hit shutout against the Senators while helping his own cause by driving in three runs and connecting on his second (and last) career homer, a solo blast off righty Camilo Pascual. By season’s end Ditmar had posted a major-league-best 1.030 WHIP over a career-high 202 innings. A respectable 13-9 record might easily have been better but too often Ditmar received little or no support from his Yankees teammates – he compiled a 1.94 ERA in nine of his 25 starts but had four losses and five no-decisions to show for it.   

In 1960 the emergence of 1959 International League pitcher of the year Bill Short, combined with unexpected challenges Ditmar encountered in spring training, relegated the veteran right-hander to the bullpen at the beginning of the season. Despite not making his first start until May 8, Ditmar became the workhorse of the Yankees staff, leading the club with 200 innings and 15 wins. Though he surrendered a club-record 25 homers, he also placed among the league leaders in ERA (3.06), winning percentage (.625), and WHIP (1.255). “He is a pitcher you can start against anybody,” Stengel exclaimed as the season drew to a close.15

This was perhaps the Old Perfessor’s mindset when he selected Ditmar to start Game One of the 1960 World Series against the Pittsburgh Pirates. (Future HOF lefty Whitey Ford might have gotten the start, but he was winless in four consecutive postseason starts dating back to 1957, and had struggled with arm problems throughout the season.) On October 5 Ditmar took the mound in Pittsburgh’s Forbes Field and absorbed a 6-4 loss after retiring just one batter while yielding a leadoff walk, a double, and two groundball singles to center. “The Pittsburgh infield was like pavement,” said the sinkerball artist. “[E]verything that was hit on the ground went through the infield like a shot.”16

Despite this difficult outing, Ditmar was the starter for Game Five at Yankee Stadium, where he had a superb 10-2, 2.29 record during the season.17 Unfortunately for the Yankees, the results were approximately the same when Ditmar yielded three runs (one earned) on three hits in 1⅓ innings. Meanwhile, two shutouts delivered by Whitey Ford in the club’s losing cause contributed to accusations that Stengel had mismanaged the staff, accusations that led to the skipper’s dismissal five days after the Series ended.

In 1961 Ditmar reported to spring training early “to avoid the weak arm which handicapped [him] at the outset in 1960.”18 This strategy paid immediate dividends in April with two wins in two starts but yielded far less success in May – 0-2, 5.14 over six starts. In June Ditmar and fellow veteran Bob Turley, who was suffering a similar fate, were removed from the rotation in favor of Bill Stafford and rookie Rollie Sheldon. On June 14, in a move to add another left-hander to the rotation, the Yankees traded Ditmar and rookie corner infielder Deron Johnson to the Athletics for Bud Daley. (At the time of the trade Ditmar was serving as the club’s interim player representative; he was replaced by Ford.)

Exemplified by the addition of 18-year-old high school grad Lew Krausse to the rotation in June, Kansas City was in the throes of a youth movement; in 1961 the A’s had little incentive to use Ditmar as anything more than a spot starter. Over 16 appearances (four starts) beginning July 4 he struggled through a 6.56 ERA and finished the season with a record of 2-8 in 108⅓ innings (his fewest innings pitched since his 1954 debut in Philadelphia).

Throughout the season sportswriters trying to understand Ditmar’s precipitous drop in 1961 frequently chalked it up to a sore arm – something the veteran righty vigorously denied. He would not be as fortunate in 1962. In spring training Ditmar hurt his arm but was able to persevere sufficiently to grab a spot in the Athletics rotation. He made four starts through May 12 but struggled with his control. On May 19 Ditmar took the mound in Washington’s D.C. Stadium and surrendered three runs and six hits in 2⅔innings. It proved to be his last major-league appearance. Six days later he was released. In June, Stengel, who was managing the expansion New York Mets, arranged a tryout for Ditmar but nothing came of this. He secured a stint with the Yankees’ Richmond affiliate in the International League but was released on July 5 after just two weeks. Determined to make his way back to the majors, Ditmar got permission to work out with the Yankees through the fall and joined the club as a nonroster invitee the following spring. But when he did not make the club in 1963, he retired.

On October 1, 1956, Ditmar married Missouri native Mary Jane Creel, a Trans World Airlines hostess four years his junior. The union produced four children (three boys and one girl) before dissolving in divorce in 1970. During these years Ditmar attended American International College in Springfield, Massachusetts, in the offseason and earned a bachelor’s degree in 1962. He remained at AIC in pursuit of his master’s degree while coaching the college’s basketball and baseball teams. (Major-league catcher Fran Healy was one of his players.) Around 1971 Ditmar married Dianne Meara, a professor at AIC, and moved to Cleveland suburb of Brook Park, Ohio, where he became the city’s director of parks and recreation. In 1986 he retired to a life of golf, tennis, and leisure in Myrtle Beach, South Carolina.

During the 1980s the Anheuser-Busch Brewing Company spun a Budweiser television commercial that incorporated the famous Bill Mazeroski homer in the 1960 World Series. The original NBC radio broadcast had incorrectly identified Ditmar as the pitcher who surrendered the Series-ending blow. (One report suggests he was warming up in the bullpen when the drive was struck.) When the audio was replayed more than 20 years after the fact, Ditmar sued the brewing company for $500,000, claiming “the commercial held him up to ‘undeserved ridicule, humiliation and contempt.’”19 A U.S. district judge threw out the case.

Throughout his playing career Ditmar was a frequent speaker at Chamber of Commerce and sports jamboree functions and, in 1960 at the annual Sportswriters Alliance Gold Key dinner in Hartford, Connecticut. In at least two years he also spent the offseason barnstorming in New England and Canada. In retirement he was a frequent participant at autograph shows and Old Timer’s Games and in 2015 he was inducted alongside West Springfield native Vic Raschi into the Western Massachusetts Baseball Hall of Fame.

Ditmar concluded a nine-year major-league career with a record of 72-77, 3.98 in 1,268 innings, a far cry from the expectations of the Athletics coaches in 1954. But with the exception of two fine seasons in the Bronx, his pedestrian record can be attributed in part to the second-division clubs for whom he played. 

He died at the age of 92 on June 11, 2021.
