Christopher Riley Martin (born June 2, 1986) is an American professional baseball pitcher for the Texas Rangers of Major League Baseball (MLB). He has previously played in MLB for the Colorado Rockies, New York Yankees, Atlanta Braves, Chicago Cubs, Los Angeles Dodgers, Boston Red Sox, and in Nippon Professional Baseball (NPB) for the Hokkaido Nippon-Ham Fighters.
Martin played baseball at Arlington High School and McLennan Community College, but gave up on baseball after he suffered a shoulder injury. After working in a warehouse for three years, Martin began playing catch, and felt strong enough to try out for independent league baseball. After he pitched for the Grand Prairie AirHogs in 2010, the Boston Red Sox of MLB signed Martin in 2011. He pitched in Minor League Baseball for the Red Sox organization, until they traded him to the Rockies after the 2013 season.
Martin made his MLB debut for the Rockies in 2014, and was traded to the Yankees after the season. He signed with the Fighters after the 2015 season, and won the 2016 Japan Series with the Fighters. He signed with the Rangers after the 2017 season. The Rangers traded Martin to the Braves during the 2019 season, and he was a part of the 2021 World Series championship team.
