Marlins, catcher Buck agree to three-year deal

Veteran hit 20 homers during first All-Star season in 2010

The Marlins have agreed to a three-year contract with free-agent catcher John Buck, the club announced on Wednesday.

Terms were undisclosed, but FOXSports.com reported the deal to be worth $18 million.

Buck is coming off a breakout year in his first season with the Blue Jays, one that saw him make the American League All-Star team for the first time and set career highs in batting average (.281), on-base percentage (.314), homers (20) and RBIs (66). While starting 104 games behind the plate, the 30-year-old threw out 28 percent of would-be basestealers.

Buck, a right-handed hitter who spent his previous six seasons with the Royals and made $2 million in 2010, sports a career .243 batting average and a .301 on-base percentage.

The Marlins went into this offseason actively pursuing catching help, with John Baker coming off Tommy John surgery and Ronny Paulino being suspended 50 games for performance-enhancing substances late last season.
