Friedrich's fall came on the final out of the seventh when he stepped to his right on Joe Panik's popup to short. With two right-handed starters on the mound, Friedrich believes he planted on the divot left by their cleats, rolling his ankle in the process.
The X-rays taken came back negative, but Weiss wouldn't specify if Friedrich would be available for Friday's game. Having pitched in the Rockies' most recent game, Friedrich would have been unlikely to be called upon, especially with expanded rosters.
Friedrich has tossed a total of 19 innings with the Rockies this season, allowing 20 runs (15 earned) while striking out 20. He started three games for Colorado earlier this year, but he's been operating out of the bullpen since his September callup.
