Thomas Kevin Layne (born November 2, 1984) is an American former professional baseballpitcher. He previously pitched for the San Diego Padres, Boston Red Sox, and New York Yankees of Major League Baseball.
Layne attended Fort Zumwalt South High School in St. Peters, Missouri, where he played baseball and soccer. He then enrolled at Southwestern Illinois College where he played college baseball for two years. He then played at the University of Central Missouri for one year before transferring to Mount Olive College in Mount Olive, North Carolina, where he played for the Mount Olive Trojans. In 2007, Layne was named an All-American and Carolinas-Virginia Athletic Conference Baseball Pitcher of the Year.
The Arizona Diamondbacks drafted Layne in the 26th round of the 2007 MLB Draft. Layne progressed steadily up the minor league ladder over five seasons in the Diamondbacks’ system and was promoted to the Triple-A Reno Aces in early 2011. Over three seasons, Layne had posted a 3.82 earned run average (ERA) working exclusively as a starter in Double-A for the Diamondbacks, but struggled in his time at Triple-A, accumulating a 6.21 ERA in 15 games started and 17 relief appearances in 2011.
The San Diego Padres acquired Layne from the Diamondbacks on May 3, 2012, for cash considerations. Layne made 5 starts and notched a 7.77 ERA for the Triple-A Tucson Padres before he was demoted to the Double-A San Antonio Missions and began working out of the bullpen. Layne was noted as having a “rubber arm” and he enjoyed having the chance to pitch every day, so he welcomed the transition to a reliever role. Layne had more success at Double-A, posting a 3.28 ERA and 36 strikeouts in 35
The Padres promoted Layne to the major leagues on August 14. Layne made his Major League debut the same night against the Atlanta Braves, striking out the side in his one inning. Layne remained with the Padres for the rest of 2012, working out of the bullpen. He didn’t allow a run in his first 11 appearances. Layne earned his first win as a Major Leaguer on September 4 when he struck out Adrián González, Matt Kemp, and Hanley Ramírez in order in the 10th inning. Layne finished the season with a 3.24 ERA and 25 strike-outs versus 3 walks in 162⁄3 innings over 26 appearances. Layne was designated for assignment on October 25, 2013.
