However, the 23-year-old right-hander turned out to be such a bust that the Marlins designated him for assignment prior to Tuesday night’s game against the Pittsburgh Pirates at PNC Park.
Left-hander Brian Flynn was recalled from Triple A New Orleans.
“It just came to a point where he wasn’t getting any better, wasn’t showing any improvement and we felt we couldn’t do anything more to help him,” Marlins manager Mike Redmond said. “Things like this are always tough, but that’s part of the business.”
Turner was 4-7 with a 5.97 ERA in 20 games, including 12 starts, this season. During his time with the Marlins, he was 8-19 with a 4.41 ERA in 47 games.
The Marlins acquired Turner, then considered one of the top prospects in baseball, in a July 2012 trade with the Tigers that sent right-hander Anibal Sanchez and second baseman Omar Infante to Detroit.
Turner was the Tigers’ first-round draft pick in 2009, the ninth overall selection. He made his major-league debut two years later at 20.
Flynn will work out of the bullpen. He made one relief appearance for the Marlins on June 27 against the Oakland Athletics, allowing two runs in three innings, and was 7-8 with a 4.00 ERA in 21 starts with New Orleans.
PENNY MAY RETURN
Turner’s next turn in the rotation would have been Saturday, and Redmond said the Marlins had yet to decide who would pitch that night against the Reds at Cincinnati.
Veteran right-hander Brad Penny, who last pitched in the major leagues in 2012, is a strong possibility. He is 2-2 with a 2.28 ERA in five starts for New Orleans, including six shutout innings Monday against Nashville in a Pacific Coast League game.
Penny, 36, made his major-league debut with the Marlins in 2000 and spent five seasons with them. He pitched in relief 22 times for the San Francisco Giants in 2012 and made one start for the Softball Hawks of the Japanese Pacific League last year before deciding to return to the United States.
“It’s August, but there’s still plenty of opportunity for someone to come up here and win a job,” Redmond said.

returned to the starting lineup after sitting out the last two games of the weekend series against the Reds because of what Redmond described as back stiffness. Saltalamacchia, though, disputed the notion he wasn’t healthy enough to play.
