Batting Utley two and Michael Young three makes sense. It puts the Phillies' two highest OBP guys at the moment in position to get on base for Ryan Howard, who at some point has to drive in a run or two. Utley has a .350 OBP and Young is at .400. Phillies second batters this season have an unimpressive .286 on-base percentage.
Of course, Young batting third might result in another double play or six. He leads the majors with six GIDPs.
The Phillies need some sort of jolt to a stagnant offense, and hopefully this mini shakeup is it. Rodriguez has been tough against all hitters in 2013, but this batting order at least forces him to change up his pitch selection on a batter-to-batter basis. By batting Utley two, the Phillies go righty-lefty-righty-lefty-righty-lefty-lefty-righty. Might not matter, but Rodriguez does use his curveball far more against lefties, so this may keep him from getting into a groove with the pitch.
John Mayberry, who has just 11 plate appearances vs. lefties this season, bats in the five-hole previously occupied by Young. Mayberry hit a triple off lefty Jeff Locke last night and owns an .878 career OPS against lefties, so this needs to be a big game for him.
