A journeyman in the best sense of the word, Kent Mercker made his name over the course of an 18-season career as a young, hard-throwing left-hander in the Atlanta Braves’ bullpen before moving to the back end of the Braves’ dream rotation in the mid-1990s that featured future Hall of Famers Greg Maddux, Tom Glavine, and John Smoltz as well as Steve Avery. Mercker’s tenure with the Braves was highlighted by both team and individual accomplishments. He was a member of the Braves’ 1991 and 1992 pennant-winning teams as well as the 1995 world championship team.
On September 11, 1991, Mercker pitched six hitless innings and got the win in a combined 1-0 no-hitter against the San Diego Padres with Mark Wohlers and Alejandro Pena. On April 8, 1994, Mercker pitched a no-hitter against the Los Angeles Dodgers.1 His career was in turmoil through the late 1990s, as he bounced from club to club, unable to sustain the promise of his early career. Around the turn of the century, Mercker transitioned back to the bullpen, reinventing himself into a crafty set-up man who relied on his control, changeups, and breaking pitches to get hitters out instead of his heat. A steady presence in unsteady “steroid-era” bullpens, Mercker enjoyed some of his greatest success when he was well into his 30s.2
In the midst of his transition to the bullpen, Mercker suffered a life-threatening cerebral hemorrhage while on the mound for the Angels. On May 11, 2000, he was pitching at home against the Texas Rangers in a rare appearance as a starter. In the second inning Mercker began to feel dizzy on the mound before dropping to one knee. Angels medical staffers took him to the University of California-Irvine Hospital, where tests revealed that he had suffered a cerebral hemorrhage. Mercker spent days in the intensive-care unit. Hospital staff members prevented the bleeding on his brain from developing into an aneurysm, which likely would have killed him. Mercker spent three months back home in Athens, Ohio, recovering before returning to the Angels bullpen in mid-August.3
For his courage and determination in a life-threatening situation, the Boston Chapter of the Baseball Writers Association of America named Mercker a co-recipient of the 2000 Tony Conigliaro Award, along with Tampa Bay’s Tony Saunders, who recovered from a career-threatening broken arm the same season. Mercker and Saunders shared the award, which is given annually to the player who “best overcomes an obstacle and adversity through the attributes of spirit, determination, and courage that were the trademarks of Conigliaro.”4
Kent Franklin Mercker was born on February 1, 1968, in Dublin, Ohio, a suburb of Columbus. The son of Franklin and Norma Mercker, he moved with his family several times during his childhood due to his father’s job as a salesman. The family settled back in Dublin in 1980. Mercker was one of Ohio’s finest high-school baseball players of the 1980s. Over four seasons he posted a 32-3 record pitching for the Dublin-Coffman High School Shamrocks. As a senior, the left-handed Mercker was clocked pitching as fast as 93 miles per hour. In 1983 he led the nearby Worthington American Legion baseball team to a third-place finish in the American Legion World Series.5
The Atlanta Braves selected the 6-foot-1, 175-pound pitcher Mercker in the first round of the June 1986 amateur draft. He proceeded quickly through the Braves organization, reaching Triple-A Richmond soon after his 21st birthday. The youngest player on the Richmond roster, Mercker went 9-12 for the 1989 International League champions, posting a 3.20 ERA in 27 starts. He received a September call-up with the sad-sack, 63-win 1989 Atlanta Braves. Mercker pitched in two games for the Braves that September. He was shelled in both outings, one of them a start, surrendering six earned runs and eight hits in 4⅓ innings.
Mercker began the 1990 season in Richmond and in late June was promoted to Atlanta. Aside from rehab assignments, he never again pitched in the minor leagues. He became a fixture in the Braves bullpen in the second half of the 1990 season, picking up seven saves in 36 appearances for yet another cellar-dwelling Braves team.
Mercker went 5-3 with a 2.58 ERA in the Braves’ 1991 dream season, working primarily as a middle reliever and occasionally as a closer (six saves). He made four starts, including one on September 11 when he pitched the first six innings of a combined no-hitter against San Diego. Mercker made three appearances for the Braves in the postseason. He took the loss at home in Game Four of the NLCS, which tied the series with Pittsburgh at two games apiece. Mercker surrendered a 10th-inning walk to the Pirates’ Andy Van Slyke, who wound up scoring the winning run when Mike Lavalliere singled him home off Mercker’s replacement, Mark Wohlers. He made two brief appearances in the seven-game 1991 World Series, holding the Minnesota Twins scoreless both times.
Mercker remained a steady presence in his 53 appearances out of the Braves bullpen in 1992. He pitched well in the NLCS, a rematch between the Braves and Pirates. Mercker held the Pirates scoreless in three innings over two outings, one of which was a blowout victory for Pittsburgh (Game Five) and the other a decisive victory for Atlanta (Game Six). He suffered a rib injury during the Braves' victory celebration after Game Seven, and was not on the World Series roster.6
Mercker returned to top form in 1993, posting a 3-1 record and 2.86 ERA in 43 appearances. He started six games from late July through September, pitching effectively but never lasting more than six innings. Mercker made a career-high five postseason appearances in 1993, all in the Braves’ defeat by the Philadelphia Phillies in six-games in the NLCS. In five innings of work, Mercker gave up just one run. He did not figure in any decisions.
In 1994 Braves manager Bobby Cox decided to make Mercker his fifth starter. The decision paid immediate dividends, as the 26-year-old lefty pitched a no-hitter and struck out 10 Los Angeles Dodgers on April 8, his first start of the season. In his first season as a regular starter, Mercker won nine of his 13 decisions and posted a 3.45 ERA during the strike-shortened season.7 His record was second best among Braves starters, next to Greg Maddux, who posted a 16-6 record with a 1.56 ERA for the second-place Braves.
After the promise of 1994, Mercker’s 1995 season proved disappointing. Though his performance was competitive with that of most fifth starters, Mercker did not develop into an ace. He went 7-8 with a 4.15 ERA. Mercker made two postseason appearances during the Braves’ run to the 1995 World Series. In Game Three of the NLDS, he got Colorado Rockies catcher Joe Girardi to fly out to end the 10th inning in a 7-5 defeat. In Game Three of the World Series, he surrendered an earned run in two innings of relief work against the Cleveland Indians in a 7-6 defeat at Jacobs Field that narrowed the Braves’ Series lead to two games to one.
In December 1995 the Braves traded Mercker to the Baltimore Orioles for right-handed reliever Joe Borowski and minor-league pitcher Chaad Stewart. Mercker struggled in Baltimore to a 3-6 record with a 7.76 ERA in 14 appearances, 12 of which were starts. In late July the Orioles sent Mercker to Cleveland for 39-year-old future Hall of Fame first baseman and designated hitter Eddie Murray. Mercker returned to a familiar role in Cleveland, posting a 3.09 ERA in 10 relief appearances, but the Indians left him off their playoff roster. (The Indians ended up losing the ALDS in four games to the wild-card Orioles. Eddie Murray, the man for whom Mercker was traded, batted .400 in the series and reached based in 9 of 18 plate appearances.)
On December 10, 1996, Mercker signed a one-year free-agent contract with the Cincinnati Reds. He was a hard-luck 8-11 as a starter for the 1997 Reds. His 3.92 ERA was well under the league-wide ERA of 4.24. His performance in Cincinnati impressed the St. Louis Cardinals enough for them to sign him to a two-year deal that ended up being worth $3.8 million. Mercker worked a career-high 161⅔ innings and won a career-high 11 games against 11 losses in 1998. His ERA ballooned to 5.07, but that mirrored a league-wide uptick in ERA to 4.31. Mercker’s teammate Mark McGwire contributed significantly to the National League’s skyrocketing ERAs with his record-breaking 70 home runs. Mercker posted a 6-5 record for the Cardinals in 1999, but his ERA remained over 5.00.
On August 24, 1999, the Cardinals dealt Mercker to the Red Sox for left-handed pitcher Mike Matthews and minor-league catcher Dave Benham. Mercker returned to form during his brief stint in Boston, going 2-0 in five starts with a 3.51 ERA for the wild-card-bound Red Sox. He made three postseason appearances for the Red Sox, who defeated the Indians in five games in the Division Series before losing to the Yankees in five games in the ALCS. Mercker started Game Four of the ALDS, lasting 1⅔ innings and surrendering two earned runs before being replaced by Rich Garces. Garces ended up with the win in Boston’s wild 23-7 victory. Mercker started Game One of the ALCS and received a no-decision in a 4-3 loss at Yankee Stadium. He lasted four innings and gave up two earned runs. Mercker took the loss in Game Five of the ALCS, the victory that clinched the pennant for the Yankees. He surrendered two runs in 3⅔ innings in the 6-1 defeat.
In January 2000 the free-agent Mercker signed a one-year, $850,000 deal with Anaheim. In a season shortened by his life-threatening cerebral hemorrhage, he made 21 appearances, 14 as a reliever and 7 as a starter. The Angels declined to offer him a new contract after the season. His 6.52 ERA and 1-3 record in 2000, as well as his medical problems, tightened the market for his services. Mercker signed a free-agent deal with the Red Sox in January 2001, but Boston released him near the end of spring training.
Mercker signed a one-year, $500,000 deal with the Colorado Rockies on February 7, 2002. Playing his first full season since 1999, he went 3-1 with a 6.14 ERA for the Rockies in 58 appearances. Mercker signed with the Reds in January 2003 and turned his career around, becoming the set-up man he had been evolving into over the previous few seasons. In 49 appearances, Mercker posted a 2.35 ERA. The Braves re-acquired Mercker down the stretch of their 2003 playoff run, and Mercker shined, surrendering just two earned runs in 17 innings of work for a 1.06 ERA. Mercker made one playoff appearance for the 2003 Braves, who lost in the Division Series to the Chicago Cubs. He pitched a scoreless eighth inning in the Braves’ 4-2 home loss in Game One.
Mercker joined the Cubs in the offseason. At age 36, he made 71 relief appearances in 2004. After the season he signed a two-year, $2.75 million deal with the Reds. The seemingly ageless Mercker made a career-high 78 appearances for the 2005 Reds. Before season-ending elbow surgery in mid-August, he pitched in 37 games in 2006 and was released after the season. Mercker sat out the 2007 season to allow his elbow to heal. In 2008 Mercker, now 40, signed a one-year free-agent contract with the Reds. Forty-year-old Kent Mercker went 1-0 in 15 appearances, missing significant action with back trouble. He pitched his last game of the season on May 31, and he got a walk-off victory over his original team, the Braves. After the season, the Reds released him and he retired.
Mercker retired with a 74-67 career mark and a 4.16 ERA, strong considering that he spent much of his 18-year career pitching in one of the most explosive offensive eras in major-league history. The left-handed hitting Mercker had a career .113 batting average with 18 RBIs. Four of them came on Mercker’s only home run, a fourth-inning grand-slam off the Florida Marlins’ Jesus Sanchez on September 2, 1998.
As of 2015, Mercker resided in his hometown of Dublin with his wife, Julia, and three daughters. In 2009 he became an occasional broadcaster on Reds radio and television broadcasts. He also worked as a professional development adviser for athletes with Excel Sports Management, based in New York City.8
