The Marlins have designated pitcher Jacob Turner for assignment, the team announced Tuesday.
Turner, 23, was the No. 9 selection in the 2009 draft by the Detroit Tigers. He made his major league debut with Detroit in 2011 at age 20.
The Marlins acquired Turner in 2012 as part of the deal that sent Anibal Sanchez and Omar Infante to the Tigers.
Turner lost his spot in the Marlins rotation when the team acquired Jarred Cosart from the Houston Astros, but regained it when Henderson Alvarez went on the disabled list last week. Turner started Sunday's game against the Cincinnati Reds and lasted just four innings, allowing nine hits and five runs as the Marlins went on to lose 7-3.
In 12 starts and eight bullpen appearances this season, Turner has an ERA of 5.97 and a WHIP of 1.647.
