As I've said elsewhere, I think there was actually a plan in the works here. Kepler becomes a full-time RF when Sano gets hurt, Plouffe starts getting playing time at other positions while Sano is playing third at AAA. When Sano is called up, Park goes down. Room to rotate Plouffe at 1st, 3rd and DH. Next would be sending Grossman down and bringing up Eddie Rosario. A youth movement sneaking up on us!
