"We're still working on that," Marlins manager Mike Redmond said. "We haven't decided yet. [Pitching coach Chuck Hernandez] and I started to talk a little bit [Sunday] about exactly what was going to be best for our young pitchers."
Miami recently replaced struggling left-hander Brad Hand -- who made two starts against the Nationals in Turner's spot -- in the rotation with the right-handed Slowey, who gave up two runs in five innings against the Mariners on Sunday.
In two starts this season, Hand gave up eight earned runs on 12 hits, walked three and struck out six in 6 1/3 combined innings. He owns a 6.35 ERA in four outings.
