VIDEO: Astros' Ryan Pressly Pulls up With Apparent Knee Injury While Fielding Ball in Game 6

Ryan Pressly was one of the best relievers in baseball this season, at least until his knee issues started to flare up in the middle of the year. He spent a chunk of time on the IL but ultimately was able to return for the end of the season and make the Astros' postseason roster. Well, when appearing for Houston in Game 6, Pressly went to field a ground ball from Didi Gregorius, and while trying to make a play at first base, he pulled up lame, clearly having re-aggravated the knock.

Pressly was removed from the game after recording the final out of the inning.

It's unclear what the extent of the injury is, but losing Pressly for any amount of time in October is a serious blow for the Astros.

Pressly was sidelined from Aug. 20 until Sept. 20 with a knee injury, and it showed its ugly head again in Game 6, knocking him out for the remainder of the night and possibly the rest of the postseason.

It certainly didn't look good, and he was visibly frustrated after he re-aggravated the injury, well aware that he wouldn't be able to continue in the game.

On the year, Pressly logged a 2.32 ERA with 72 strikeouts in 54.1 innings.
