The Phillies reinstated Keller (forearm) from the injured list Wednesday.
Keller had been on the shelf since June 16 with right forearm tendinitis, but after making two rehab appearances at Triple-A Lehigh Valley, he's officially been cleared to return to Philadelphia's bullpen. The 30-year-old owns a 4.15 ERA and 1.35 WHIP through 30.1 innings on the season and will likely slide back into a setup role now that he's fully healthy. Seth Johnson was optioned to Triple-A in a corresponding move.
