After being activated off the disabled list with a supposedly healed left-foot fracture, Pedroia was only able to play in two games before sitting out Thursday's game and going on the disabled list Friday. According to MLB.com's Ian Browne, Pedroia said there has been no further damage, but it's clear the foot isn't healed enough yet.
Managing only a 1-for-7 showing at second, Pedroia cannot return until at least September 1. When he does so, he will have a .288/.367/.493 line in 351 plate appearances.
With Pedroia out of action, Jed Lowrie and Bill Hall will receive the bulk of playing time at second. That means additional time in left for Daniel Nava, as Hall would have grabbed a few starts in left field. Instead, Nava and Darnell McDonald will assume the bulk of time in left.
The Red Sox previously placed Eric Patterson on the disabled list, so he is unavailable to replace Pedroia on the roster and grab a few starts of his own and second and left. As a result, 22-year-old Yamaico Navarro leapfrogs Niuman Romero to get the call.
Navarro was recently promoted to Triple-A Pawtucket from Double-A Portland and has only 53 at-bats to his name at the higher level. He hit .283/.339/.528 with three dingers, so is clearly on a good streak. For Portland, he was working on a .274/.358/.422 line in 329 trips to the plate. He has a reputation for being a good defender, albeit on the flashy side. He is a shortstop but has played third base a significant amount of the time due to Jose Iglesias' entrance into the farm system in the offseason. He'll provide a solid glove as a backup player.
Navarro is not on the 40-man roster, but there is space available so there will not need to be a corresponding move.
