Jhoulys Chacin SP COL 17 Days

Jhoulys Chacin (shoulder) won't need surgery, but will be shut down for 4-6 weeks.

Chacin was diagnosed last week with a strained right rotator cuff and fraying in the front of his labrum. While he'll avoid surgery, he has a long way to go before pitching with the Rockies again.

Rockies transferred RHP Jhoulys Chacin from the 15-day disabled list to the 60-day disabled list.

The move clears a spot on the 40-man roster for Jair Jurrjens. Chacin is dealing with a strained right rotator cuff and fraying in the front of his labrum and is out indefinitely.

An MRI has revealed that Jhoulys Chacin has a strained right rotator cuff and fraying in the front of his labrum.

He'll receive a second opinion before the next course of action is determined, but obviously the right-hander will be sidelined for a while. It's not clear at this point if surgery might be a possibility. Chacin was placed on the disabled list Monday after admitting over the weekend that he's had shoulder strength issues.

Rockies placed RHP Jhoulys Chacin on the 15-day disabled list with right shoulder inflammation.

Chacin acknowledged to reporters Saturday that he's been having issues with arm strength throughout the 2014 season. And it's shown in his stat lines. The 26-year-old hits the disabled list having posted a 1-7 record, 5.40 ERA, and 1.44 WHIP across 11 starts. He missed all of April with a similar shoulder issue.

Jhoulys Chacin admitted after Saturday's start to being concerned with his lack of arm strength so far this season.

Chacin is averaging a career-low 88 mph with his fastball this year and was sitting mostly at 86 mph on Saturday, when he was roughed up for seven earned runs in 5 2/3 innings by the Brewers. "I really don't know what's wrong with my arm. I can't get strong," Chacin said. "Even if I throw extra hard, I can get one (pitch), but then I can't throw the next one hard." Chacin missed the first month of the season with a shoulder issue but insists that he doesn't feel any pain. He'll hope to eventually regain some pep to his fastball, but fantasy owners should obviously steer clear of him for now.

Jhoulys Chacin fell to 1-7 after yielding seven earned runs in 5 2/3 innings Saturday to the Brewers.

Chacin also got roughed up Monday by the Cardinals and now holds an ugly 5.40 ERA on the season. Milwaukee got to him for 11 hits on Saturday -- including two doubles, a tripe, and a Carlos Gomez home run.

Jhoulys Chacin dropped to 1-6 after giving up five runs in six innings Monday against the Cardinals.

Chacin was coming off three straight quality starts, but only one of those (7 scoreless against the Braves on June 12) was all that strong of an outing. His velocity isn't what it was, and it doesn't look like he's going to return to being the guy who was among the NL's 10 best pitchers last year.

Jhoulys Chacin yielded three runs and seven hits in six innings Tuesday in a loss to the Dodgers.

Chacin was coming off his best start of the season, blanking the Braves for seven innings on Thursday. This time around, he struck out five, walked three and gave up a pair of homers (to Hanley Ramirez and Matt Kemp). Chacin entered the game 0-2 with a 5.32 ERA in four road starts. With Coors Field as the alternative, you can see why it's a little hard to trust Chacin (4.53 ERA) in fantasy right now. The right-hander hosts St. Louis on Monday.

Jhoulys Chacin finally won for the first time this season by blanking the Braves for seven innings on Thursday.

Chacin had been 0-4 with a 5.35 ERA in seven starts since returning from a shoulder injury. Today's game was easily the most run support he's gotten (eight runs while he was in the game, 10 overall), on the one occasion that he didn't really need it. Chacin is still merely a fringe play in NL-only leagues right now.

Making his second start since coming off the DL, Jhoulys Chacin yielded two runs and four hits in six innings Friday in a no-decision against the Reds.

Chacin gave up a long, long, long home run to Todd Frazier, but he shook that off and turned in a pretty nice outing, albeit one against a struggling, banged-up offense. We still wouldn't use him in mixed leagues yet.
