Second baseman Freddy Galvis is headed to the 15-day disabled list with a lower back strain. The injury occurred on a swing in the fifth inning of Wednesday night's 6-5 loss to the Dodgers.
A corresponding roster move is expected on Thursday. Pete Orr, who was optioned on Wednesday, could be headed right back to Philadelphia. Michael Martinez is another possibility.
Mike Fontenot took over for Galvis on Wednesday night. He's the leading candidate to see increased playing time with Galvis' injury.
"Another one of our guys going down," manager Charlie Manuel said. "What more can I say?"
After taking a swing, Galvis was briefly examined by head athletic trainer Scott Sheridan and Manuel. Galvis tried to stay in the game, but after taking a half-swing during the eighth pitch of the at-bat, Galvis signaled to the dugout and exited.
Galvis had already left the ballpark by the time the clubhouse was open to reporters after the game.
Galvis, who is filling in for the injured Chase Utley, was batting .226 with three home runs, 14 runs scored and is tied for fourth on the team with 24 RBIs. The 22-year-old Venezuelan has been very impressive in the field, even though his natural position is shortstop.
He had played in every game this season.
The Phillies can't seem to catch a break in terms of injuries this season. Already without Utley and Ryan Howard, the club is also missing ace Roy Halladay, outfielder Laynce Nix and four relievers in Jose Contreras -- out for the season -- Michael Stutes, David Herndon and Justin De Fratus. Cliff Lee, Vance Worley and Jim Thome have also all spent time on the DL this season.
"A lot of veteran players are in here that understand that injuries are a part of baseball and a part of sports in general," infielder Ty Wigginton said. "You've just got to roll with the punches, and we'll have somebody step in for him and hopefully catch fire for us."
