Pirates' Mitch Keller: Returning to majors

Keller was recalled from Triple-A Indianapolis on Friday, Jason Mackey of the Pittsburgh Post-Gazette reports.

The 25-year-old has been in the minors since mid-June and will rejoin the big-league roster ahead of this weekend's series versus the Phillies. Keller last pitched for Indianapolis on July 24, and he finished the stint at Triple-A with a 3.21 ERA, 1.43 WHIP and 39:13 K:BB over 28 innings. It's not clear when he'll take the mound, though he could slot into the rotation Sunday since Pittsburgh has yet to announce a starter for that day.
