Draft and minor leagues Kapler was the 57th-round draft pick (1,487th overall) of the
Detroit Tigers in the
1995 Major League Baseball draft. He was signed by scout Dennis Lieberthal, father of former Phillies catcher
Mike Lieberthal, after being offered a $10,000
signing bonus. He made the South Atlantic League All-Star team. He then played for the
West Oahu CaneFires in the
Hawaiian Winter League, leading the league in home runs with 7. In 1997, with the
Lakeland Flying Tigers, Kapler led the Class A+
Florida State League in doubles (40) and total bases (262), tied for first in extra-base hits (65), was 2nd in games, 3rd in hits (153), tied for 3rd in home runs (19) and RBIs (87), 4th in slugging percentage (.505), and tied for 4th in runs (87) and sacrifice flies (10), while batting .295. He was named a Florida State League mid-season and post-season All-Star. and was named Tigers Minor League Player of the Year and Detroit's No. 1 prospect by
Baseball America.
Detroit Tigers (1998–1999) Kapler made his Major League debut in 1998 at the age of 22. He became the first Tiger since the inception of the draft in 1969 to be selected as late as the 57th round, and reach the majors. For the season, Kapler wound up hitting a career-high 18 home runs in just over 400
at bats, third among AL rookies, and his 49 RBIs were ninth among AL rookies.
Texas Rangers (2000–2002) In November 1999, he was traded by the Tigers with Al Webb,
Frank Catalanotto,
Francisco Cordero,
Bill Haselman, and
Justin Thompson to the
Texas Rangers for
Juan González,
Danny Patterson, and
Gregg Zaun. Kapler hit two home runs on
Opening Day in the 2000 season for the Rangers, becoming the first player to homer in his first two at bats as a Ranger. In July he homered in four straight games, tying a club record. On July 30, he was named the
American League's
Player of the Week.
Colorado Rockies (2002–2003) In July 2002, the Rangers traded Kapler, with
Jason Romano and cash, to the
Colorado Rockies for
Dennys Reyes and
Todd Hollandsworth. Playing for the Rockies in 2002, he batted .311/.359/.445 in 119 at bats. Kapler played a career-high 136 games in 2004, hitting 6 home runs and driving in 33 runs in 290 at bats, as he primarily played
right field.
Yomiuri Giants (2005) Less than one month after the Red Sox dramatic 2004 World Series victory, Kapler departed to play for Japan's
Yomiuri Giants. He received a $2 million deal plus a $700,000
signing bonus, compared to the $750,000 salary he had received from the Red Sox. Driven by the memory of an elementary-school report that he had written about Japan, he felt it was time for a change. "I tend to make emotional decisions," he said. "I did it more for the life experience than anything else. And ever since I wrote that report, I've been fascinated by everything that an 8-year-old associates with a country far, far away." On September 14, 2005, Kapler ruptured his left
Achilles tendon while rounding second base after a home run by teammate
Tony Graffanino. Kapler was replaced by pinch runner
Alejandro Machado, who finished rounding the bases and scored the run in Kapler's place. Kapler had surgery, which ended his season.
Minor league managerial career (2007) He served the Boston Red Sox as manager of their Single-A affiliate, the
Greenville Drive, for one season in 2007. The team went 58–81, and finished in 7th place in the
South Atlantic League Southern Division.
Milwaukee Brewers (2008) On September 20, 2007, after one season as a manager, Kapler announced that he would like to return to play Major League Baseball in 2008. On the decision, Kapler said "I miss the battle. I still need to be on the field as a player." {{Quote box |width=77% | bgcolor= |align=center | quote="He knows he has to come in and win a job. I don't think this was about the money for him. It was about getting a chance to play again. He has great work ethic. People love the way he plays the game. He's a guy with Major League experience and can play all three outfield positions. And this guy is in better shape than our 25-year-old guys." The initial plan, before
Mike Cameron was acquired, was to have Kapler replace the non-tendered
Kevin Mench as a right-handed option to share time with
Tony Gwynn Jr.,
Gabe Gross, and
Joe Dillon, in
left field. With a focus on defense, Yost indicated in March that Gwynn and Kapler might have a leg up on Gross. "He's been very impressive so far," said Brewers manager
Ned Yost in March. "I would have never known he took a year off. He does not show any signs of it to me. While Cameron served a 25-game suspension to start the season for twice testing positive for a banned
stimulant in the fall of 2007, Kapler made the club, and began to see action in center field. On April 5, 2008, he hit the first
pinch-hit home run of his career for Milwaukee in the 7th inning of a game against the
San Francisco Giants. Kapler started the season as the Brewers' hottest hitter, going 11-for-26 with four home runs and 11 RBIs. Kapler gave fans a taste of his hard-nosed style against the
Dodgers on August 16. He ran full-speed after
Russell Martin's long fly in the seventh inning, snagging the ball to deprive Martin of a home run as he toppled head-first into the left-field seats. The outstanding catch helped the Brewers hold onto a one-run lead, and earned Kapler the Play of the Year Award, voted by over 12 million fans in MLB's
This Year in Baseball Awards. Similarly, three days later Kapler made a diving catch in left field to rob
Ty Wigginton of a hit, and on September 6 Kapler ran down a blooper to center and made an outstanding diving catch. Kapler missed the last two weeks of the season as well as the
NLDS after tearing his
latissimus dorsi muscle in his right shoulder on a throw to the plate in mid-September. For the year, in 96 games Kapler batted .301/.340/.498, and hit eight home runs, playing mostly in center field, and batting .386 with a .632 slugging percentage in tie games. On October 30, 2008, Kapler filed for
free agency.
Tampa Bay Rays (2009–2010) in 2009 On January 12, 2009, Kapler signed a one-year contract with the
Tampa Bay Rays for $1,000,018. The extra $18 was chosen because it represented the
symbol for "life" in Judaism. Kapler started the season
platooning in center field with
Matt Joyce, in place of Rays' center fielder
B. J. Upton, who had offseason surgery on his left shoulder and was not ready for Opening Day. Kapler then began to platoon in right field with Gabe Gross. In June, he tied a club record shared by
Jose Canseco and
Julio Lugo, with home runs in four straight games. In this role, he almost broke up
Mark Buehrle's perfect game on July 23, 2009. Leading off the ninth inning against the
White Sox, he was robbed of a home run by a leaping
DeWayne Wise, a ninth inning defensive replacement. Through July 10, despite a slow start, Kapler had the best slugging percentage of his career (.505) and was batting .320 with 4 home runs in 75 at-bats and a .680 slugging percentage against left-handers. As of July 10, 64% of his hits in 2009 had been for extra bases, which would be first in the major leagues for a player with at least 100 plate appearances (Kapler had 129). Kapler was re-signed by the Rays on October 27, 2009, to another one-year contract, this time for $1.05 million. Over 2008–09, Kapler hit .304 against left-handers with a .577 slugging percentage, 9th-best in the Major Leagues. In a December interview manager
Joe Maddon said: "I'm still a big Gabe Kapler fan. You look at his
OPS over the last couple of years versus left-handed pitching, it's among the best in all of baseball". Heading into
spring training in 2010, Kapler was likely to platoon in right field with Joyce. However, he appeared in only 59 games that season, hitting a career-worst .210 with only two home runs as he battled right
hip flexor and right ankle injuries, and became a
free agent after the season. He also received an invitation to spring training. Kapler was released on March 31, in the team's last cut of spring training. ==Post-playing career==
