PHILADELPHIA — Pittsburgh Pirates second baseman Josh Harrison will likely miss the rest of the season with a strained right groin.

Harrison was injured Saturday after legging out a two-run double in the sixth inning. Harrison began limping after rounding first base on the ball hit into the right-center-field gap. He was able to slide safety into second base and then pounded the bag with his left fist in frustration before walking gingerly off the field.

In 131 games this season, Harrison is hitting .283 with four home runs and 19 stolen bases.

Harrison was expected to miss four to six weeks, which would cost him the rest of the season. But he hoped he could return if the sub.-500 Pirates made the postseason.

Sean Rodriguez was in the lineup at second base Monday night against the Philadelphia Phillies.
