Turner, 23, was originally selected by the Detroit Tigers in the first round (ninth overall) of the 2009 Draft and was the centerpiece of the July 23, 2012 five-player trade that sent pitcher Anibal Sanchez to Detroit. After starting 2013 at Triple-A New Orleans, Turner joined the Marlins at the end of May and went 3-8 despite a 3.74 ERA (49 ER/118.0 IP) in 20 major league starts. Turner has split the 2014 campaign between Miami's rotation and bullpen, going 4-7 with a 5.97 ERA (52 ER/78.1 IP) in 20 appearances, 12 as a starter.
After making his big league debut for Detroit with a brief three-start stint as a 20-year-old in 2011, Turner entered 2012 ranked as Detroit's number one prospect by Baseball America. Upon joining the Marlins organization in July, Turner made two starts for Triple-A New Orleans before earning a promotion to the Marlins, for whom he went 1-4 despite a 3.38 ERA (16 ER/42.2 IP) in seven starts.
The 6-foot-5, 215-pound Turner is a native of St. Charles, Mo. and was drafted by the Tigers out of Westminster Christian Academy after being named the 2009 Gatorade Player of the Year in Missouri. He made his professional debut in 2010, pitched in the Futures Game in 2011 and made his big league debut a couple of weeks later on July 30, 2011 at 20 years, two months and nine days, the youngest Tigers pitcher in more than 30 years.
Turner is 9-21 with a 4.77 ERA (140 ER/264.0 IP) in 53 major league appearances (45 starts) covering the last four seasons with Detroit (2011-12) and Miami (2012-14).
