The Phillies announced Tuesday that rookie third baseman Maikel Franco has been placed on the 15-day DL with a small fracture in his left wrist, an injury that General Manager Ruben Amaro Jr. said could put Franco out for the year.

In a corresponding move, the club called up outfielder Aaron Altherr from Triple-A Lehigh Valley.

Franco was injured last Tuesday when he was hit by a Jeremy Hellickson pitch in a game against the Diamondbacks. Initial X-rays that night were negative, but Franco showed no improvement after a few days and was sent for an MRI this week, which revealed the small fracture.

Phillies third baseman Maikel Franco was lifted from Tuesday night’s game against the Arizona Diamondbacks in the first inning after being hit in the left wrist by a pitch.

X-rays on the wrist were negative per The Philadelphia Daily News’ Ryan Lawrence, who also tweeted that Franco was diagnosed with a left wrist contusion.

Franco almost immediately dropped to the ground behind home pate after being hit by Jeremy Hellickson’s 90 MPH fastball, and looked to be in severe pain. The rookie was quickly attended to by a trainer and removed from the game.
