During his warm-ups Wednesday, Colorado Rockies’ German Marquez was helped off the field. After appearing to injure his left leg, the starter was hardly able to place any weight on it.

The injury came directly after a pitch in which Marquez torqued his knee and hobbled off the mound. An official diagnosis has yet to be announced, though General Manager Jeff Bridich said it was merely full body cramping.

The exit was in the midst of a six-inning start. To that point, he’d struck out a season-high 10 hitters and allowed a mere two hits against the Los Angeles Dodgers.

On the year, the hurler has a 4.68 earned run average across a team-high 24 starts.

The injury adds to an already-depleted rotation. Since the start of the year, Chad Bettis, Tyler Anderson and Kyle Freeland have all dealt with issues. Both Bettis and Freeland were booted from the rotation at one point, with the former currently serving as a long reliever in the club’s bullpen.

Pending the result of their series finale against the Dodgers, the Rockies are 50-58 and sit at the bottom of the National League West standings.

Anderson is currently out for the year after undergoing left knee surgery.
