The Texas Rangers now believe the injury to outfielder Josh Hamilton, previously described as a strained groin, is actually a sports hernia, which could require surgery after the season. However, one thing has not changed: Hamilton intends to play the rest of the World Series.

“We’ve talked about me not being as aggressive [on the field], because it hurts when I’m aggressive,” Hamilton said prior to Saturday night’s Game 3. “But I just have to go and play my game.”

Hamilton was in the Rangers’ lineup in his customary No. 3 spot and playing center field for Game 3. However, the injury has obviously reduced his effectiveness. He entered Saturday night’s game hitting .250 this postseason with a .354 slugging percentage, and had been held homerless in 12 postseason games.

“He’s less than 100 percent,” General Manager Jon Daniels said. “But he’s good enough to go.”

Hamilton previously suffered from a sports hernia during the 2009 season, which ultimately required surgery and cost him more than a month of the season. It remains unknown whether Hamilton’s current injury will also require surgery, but Daniels said it would be addressed within a week of the end of the World Series.
