After allowing seven runs (six earned) Monday against the Dodgers the Phillies finally pulled the plug on pitcher Sean O'Sullivan, outrighting the right-hander to Triple-A Lehigh Valley.

The 27-year-old has been miserable this season for the Phillies posting an 6.08 ERA with a 1.61 WHIP over 71 innings. across 13 starts this season.

To replace him on the roster for tonight game in Los Angeles, the Phillies recalled reliever Hector Neris, but the big question will be who will take his place in the rotation when his turn comes back up this weekend against the Giants.

Could we see Aaron Nola?

The Phillies top pitching prospect is 10-3 with a 1.97 and a 0.97 WHIP in 16 games this season between Double and Triple-A and is clearly the best option to come up and replace O'Sullivan.
