Freddy Tarnok Injury: Nursing ankle sprain

The Marlins placed Tarnok on the 15-day injured list Saturday, retroactive to Wednesday, with a sprained left ankle.

Tarnok has given up two earned runs in 5.1 innings since coming up from Triple-A Jacksonville, but he's now due to remain sidelined until at least Sept. 18. Christian Roa was selected from Triple-A to fill the open spot in Miami's bullpen.
