It sounds like a very minor issue, and Walker said he expects to be fine for his next start. However, the Phillies do have Ranger Suárez almost ready to replace him in the rotation. Walker has been a great surprise in allowing just five earned runs over 19 2/3 innings to date, but he’s still the only candidate for a demotion in the Phillies rotation.

We’re guessing some sort of ailment was involved here, but the Phillies didn’t say anything about it during the game. Walker had walked three batters, but he was at just 56 pitches when he was replaced by Matt Strahm.

All of the runs came in the second, and Walker made things a whole lot worse then by throwing a potential double-play ball into center field with one out and only one run in. Walker did well afterwards, allowing just one hit over his final three innings of work, but the damage was done. He’ll get the Marlins next.

Walker also walked three and struck out five, but needed 94 pitches to get 14 outs. He posted a 21 percent whiff rate and 23 percent CSW and only had his sinker perform as a consistently solid offering on the night. We know that Walker hasn’t allowed a run yet this season, but he doesn’t look that inspiring on the mound and is a risky bet against the Giants next week.
