DENVER (AP) -- The Colorado Rockies have optioned struggling right-handed pitcher Jhoulys Chacin to Triple-A Colorado Springs.

The team will make another roster move before the game Friday against Atlanta.

Chacin was 0-3 with a 7.30 ERA this season. He was coming off a performance Tuesday night against the Los Angeles Dodgers in which he gave seven runs and 11 hits in just 4 2-3 innings. The 24-year-old hasn't won since Aug. 28.

Before the game Wednesday, manager Jim Tracy hinted a move could be made with Chacin so he could work on ironing out his mechanics.

Said Tracy: "We have to move forward and keep investigating. We need this guy."
