LaRoche was lost in the second inning when he suffered a separated shoulder in a collision with Phillies catcher Mike Liberthal. Jones was hit on the left knee with a Randy Wolf pitch in the first inning.
“This is just the way things are going for us right now,” Andruw Jones said. “When guys go on the disabled list, guys are going to just have to step up and do the job.”
Reserve infielder Perez did just that for the Phillies in Friday’s win, as he tied the game with an RBI double in the eighth inning and won it with his homer in the 10th.
Perez, starting in place of injured slugger Jim Thome, wasn’t the only Phillie to produce in another’s absence.
Chase Utley, starting for injured second baseman Placido Polanco, singled off Chris Reitsma with one out in the eighth to extend his hitting streak to 11 games. Perez followed with a double down the right-field line, scoring Utley and tying the game at 2.
“They know what their role is and they work hard,” Philadelphia manager Larry Bowa said of his reserves. “To see them get rewarded is nice.”
The Phillies have won three of their last five games, and remain one game behind Florida for the NL East lead.
