September 8, 1957: Toronto Maple Leafs clinch International League pennant on Humberto Robinson’s six-hitter

The Toronto Maple Leafs’ magic number was one heading into the final day of the International League’s 1957 regular season. To clinch the pennant, they needed to beat the Rochester Red Wings or have the Buffalo Bisons lose to the Montreal Royals. Toronto manager Dixie Walker handed the ball to his top starting pitcher, 27-year-old righty Humberto Robinson.

Robinson went the distance while limiting Rochester to six hits in a thrilling 4-3 Toronto victory. It was the Maple Leafs’ third regular-season title in four seasons and their 10th since joining the Eastern League in 1896, which became the IL in 1912.

The Maple Leafs had been owned by flamboyant businessman Jack Kent Cooke since July 1951. Less than two weeks after becoming owner, Cooke integrated the Maple Leafs by signing Negro Leagues legend Leon Day and third baseman Charlie White from the Winnipeg Buffaloes of the independent ManDak League.1 Cooke’s flair for promotions helped increase attendance by more than 50 percent in 1952, kicking off a five-year period in which the Maple Leafs drew the most fans in the league.2

Toronto’s affiliation with the St. Louis Browns was not renewed for 1953, and the team began operating as one of the league’s few independent teams.3 Cooke’s willingness to spend money on veterans with major-league experience, coupled with his openness to signing Black and Latino players, led to Toronto’s first-place finish in 1954, ending an 11-year pennant drought.

Robinson had made his big-league debut with the Milwaukee Braves on April 20, 1955, becoming the first Panamanian to play in the National or American League.4 He spent most of 1955 and ’56 in Triple A, where he compiled a combined 2.89 ERA in the American Association and a 2.93 ERA in 14 big-league appearances with the Braves.

Robinson was expected to make Milwaukee’s roster in 1957, and on April 1 manager Fred Haney indicated that he might be one of two relievers used in high-leverage situations.5 But the next day Robinson, who could be sent to the minors without being placed on waivers, was optioned to Toronto by the pitching-rich Braves. “Robinson can admittedly pitch better than some of those still on the roster,” wrote the Milwaukee Journal, “but under the circumstances there simply is no room for him.”6

The lanky hurler joined a Toronto team that was easily the oldest in the IL.7 Veterans included a spry 40-year-old former Negro Leagues star, Sam Jethroe; 38-year-old Cuban shortstop Héctor Rodríguez, 36-year-old southpaw Johnny Schmitz, and 35-year-old slugger Mike Goliat.8 Of the 28 players used by the Maple Leafs in 1957, only three never appeared in the major leagues.9

Toronto was in first place at the end of June, but all four Maple Leafs outfielders were injured in July,10 knocking the team 4½ games out of first by July 30. The next day Cooke opened his checkbook and purchased the contract of 33-year-old center fielder Cal Abrams from the IL’s Miami Marlins.11 Abrams quickly became an effective leadoff hitter and offensive sparkplug for Toronto.12 In mid-August Cooke also bought the contract of 33-year-old slugging outfielder Archie Wilson from an American Association team.13 For the remainder of the season, Wilson was Toronto’s best hitter.14

Toronto began the final day of the regular season in first place, a half-game ahead of Buffalo thanks to a six-game winning streak that raised its record to 87-65.15 The previous day, Toronto had eliminated the fifth-place Red Wings, leaving Rochester out of the Shaughnessy playoffs for the first time since 1947.

Robinson, boasting a 17-7 record and a 2.94 ERA, was opposed by 23-year-old Kelton Russell. The Rochester southpaw began the year in Omaha − the Cardinals’ other Triple-A affiliate − before being transferred to the Red Wings on June 11 to make room for 21-year-old Bob Gibson.16 Russell came into the season finale with a 5-4 record and a 3.57 ERA with Rochester.

Both starting pitchers breezed through the first five innings, and Rochester drew first blood in the sixth. After walking left fielder Tom Burgess, Robinson surrendered a two-run homer to former Maple Leafs star Ed Stevens.17

Toronto responded with a single run in the bottom of the sixth on a double by Wilson and a solid single by Rocky Nelson that rocketed through the legs of Stevens at first base.18 Nelson’s single extended his hitting streak to 20 games, gave him 102 RBIs for the season, and cut Rochester’s lead to 2-1.19

Toronto threatened again in the seventh. With a runner on first, Rochester center fielder Gary Geiger robbed third baseman Stan Jok of a potential triple with a spectacular running catch about 400 feet from home plate, drawing comparisons in newspaper coverage to Willie Mays’s catch of Vic Wertz’s drive in Game One of the 1954 World Series.20 Although Geiger prevented Toronto from tying the game, fans at Maple Leaf Stadium gave him “one of the day’s bigger rounds of applause.”21

When the Maple Leafs came to bat in the eighth, they were aware that Buffalo was winning in Montreal and a late rally was needed to lock up the pennant.22 Russell had surrendered just six hits in the first seven innings,23 but things quickly unraveled for him in the eighth.

Rodríguez opened the inning by tripling to the scoreboard in left-center field, and Wilson followed with his fourth homer since joining Toronto three weeks earlier.24 Suddenly, Toronto had a 3-2 lead. One out later, Goliat added an insurance run with his 28th homer, tying him with Nelson for the team lead. That ended Russell’s outing, and righty Mel Wright came on to get the last two outs.25

Goliat’s insurance run proved crucial, as Rochester scored a run in the ninth on a single by Gene Green, a wild pitch, and a two-out pinch-hit single by Dave Ricketts.26 With Ricketts representing the potential tying run on first, player-manager Cot Deal batted for Wright. After Deal took a mighty cut and came up empty, Robinson ended the game by retiring him on a routine groundout.27 The Leafs’ dugout emptied, with the players swarming Robinson in celebration.28

Robinson had limited the Red Wings to three runs on six hits with two walks and three strikeouts. He earned his 18th victory of the season, tying him with Buffalo’s Walt Craddock for the most in the IL. Robinson also tied for the league lead in starts (30) and innings pitched (226), and his five shutouts were the second most by an IL hurler.29

In the best-of-seven semifinals, Robinson started Game Three in Miami against the Marlins’ 51-year-old future Hall of Famer Satchel Paige.30 Both starters took a no-decision in a 7-4 Toronto loss. Miami won the series in six games, preventing an expected Robinson-Paige rematch in Game Seven in Toronto.31 In contrast to the Maple Leafs’ regular-season success, they had not won a playoff championship since 1934.

Robinson made the Milwaukee roster out of spring training in 1958 as a reliever. He appeared in just two of the team’s first 33 games,32 and despite finishing with the best ERA (3.02) and WHIP (1.032) in the Braves’ bullpen, he made just 19 relief appearances all season. Robinson did not appear in the World Series, which the Braves lost in seven games to the New York Yankees.

Milwaukee traded Robinson to the Cleveland Indians in April 1959 for the soon-to-be-41-year-old Mickey Vernon. A month later Cleveland dealt him to the woeful Philadelphia Phillies, where he made 31 appearances and led their bullpen in ERA (3.33) and WHIP (1.288).

In late July 1960, Robinson had the second-best ERA in the Philadelphia bullpen. But the rebuilding Phillies sent the 30-year-old hurler down to Triple-A Buffalo to make room for a hot pitching prospect, Art Mahaffey. Robinson never pitched in the big leagues again. In parts of five major-league seasons, he compiled an 8-13 record and a creditable 3.25 ERA (120 ERA+).

Toronto won the IL pennant in 1960 and finally broke its playoff jinx by winning the Governors’ Cup.33 The Hamilton, Ontario-born Cooke sold the Maple Leafs in January 1964, and while he never succeeded in bringing a major-league team to Toronto, he went on to own U.S.-based teams in the NFL, NBA, and NHL.34

After winning back-to-back Governors’ Cups in 1965-66, Toronto played just one more season in the IL.35 Poor attendance in an aging and poorly maintained ballpark doomed the franchise, which was relocated to Louisville, Kentucky.36 Almost 10 years later, professional baseball returned to the provincial capital when the expansion Toronto Blue Jays began play in the AL.

Notes

1 The 34-year-old Day pitched only one season in Toronto. He recorded a 1.58 ERA in 40 innings pitched. White played for Toronto in 1951 and ’52. Neil MacCarl, “Leafs Sign Two Negroes, Give Orchids, Beat Bisons,” Toronto Daily Star, July 14, 1951: 14.

2 Toronto’s attendance went from 296,847 in 1951 to 446,040 in 1952. The NL’s Boston Braves drew only 281,278 fans in 1952. The Maple Leafs led the IL in attendance for five consecutive seasons (1952-56) before they were surpassed by the Buffalo Bisons in 1957.

3 The Maple Leafs were operated as an independent team from 1953 until the end of the 1959 season. The IL had two independent teams from 1953 to 1956. Toronto was the league’s only independent team from 1957 to 1959.

4 Several Panamanians had played in the Negro Leagues later regarded as major leagues, including Frank Austin, the Negro National League batting champion in 1945, and Pat Scantlebury, who helped pitch the New York Cubans to the Negro League World Series title in 1947.

7 Toronto batters were on average 32.9 years old in 1957; the average pitcher was 30.7 years old. IL players were on average 28.1 years old.

8 The ages listed are as of September 8, 1957.

9 The three Toronto players who never reached the big leagues were outfielders Lew Morton (129 games played in 1957) and Russ Rac (100 games), along with pitcher Larry Donovan (4 games).

10 The Maple Leafs were forced to use infielders and pitchers in the outfield, and they lost eight of 10 games from July 23-30. Sam Jethroe was injured on July 19 and returned to action on July 30. Russ Rac was struck in the head with a thrown ball while running the bases in the same game Jethroe was injured. Rac missed three games and complained of concussion-like symptoms when he returned. Jack Daniels was placed on the disabled list on July 28 and was limited to pinch-hitting duties for the rest of the season. Lew Morton also played with a pulled rib muscle.

12 Abrams had led the IL with 119 walks in 1956. In 1957 he walked 76 times in 467 at-bats.

13 Cooke announced that Wilson’s contract had been purchased from the Charleston (West Virginia) Senators on August 16. Wilson played for the Maple Leafs from 1954 to 1960. Neil MacCarl, “Archie Wilson Back in Fold,” Toronto Daily Star, August 17, 1957: 27.

14 Wilson hit .329 with four homers and 16 RBIs in 23 games with Toronto. His on-base plus slugging percentage (OPS) was .957.

15 Toronto played one fewer game than Buffalo because it was unable to replay a tie game against the Miami Marlins. The game on April 17 was stopped in the 16th inning because of a curfew and the two teams were rained out the next day.

16 Russell was also sent to Rochester because the Red Wings were in need of left-handers. “Russell Leaves,” Omaha Evening World-Herald, June 12, 1957: 33; George Beahon, “Verdi, Lovenguth Star in Wings’ 5-4 Victory,” Rochester Democrat and Chronicle, June 13, 1957: 45.

17 After appearing in parts of six big-league seasons, Stevens played for Toronto from 1952 to 1956. He led the IL with 113 RBIs in 1952 and 1954.

19 The Globe and Mail incorrectly reported that it was Nelson’s 101st RBI. Baseball Reference credits him with 102 RBIs in 1957 and this was the final game of the regular season. He finished second in the league in RBIs behind 42-year-old Luke Easter of the Bisons. Easter had a career-high 128 RBIs. Nelson won the Triple Crown with the Maple Leafs in 1958 – his age 33 season. He hit .326 with 43 homers and 120 RBIs, earning him a three-year stint with the Pittsburgh Pirates. He had previously spent parts of six seasons in the big leagues.

29 Jim Coates of the Richmond Virginians led the league with six shutouts. Coates also pitched 226.0 innings. Four players other than Robinson started 30 games.

30 Four years after he last pitched for the St. Louis Browns, Paige led the IL with a 0.916 WHIP in 119 innings on the mound. His 2.42 ERA was third best in the league among pitchers with at least 50 innings pitched.

They won the Governors’ Cup four times: 1934, 1960, 1965, and 1966. Toronto defeated the American Association champions in the Little World Series in 1907 and 1926. The Little World Series was renamed the Junior World Series in 1932. The Maple Leafs appeared in the Junior World Series twice (1934 and 1960), losing both times.
