Estevez (oblique) will be placed on the disabled list to start the regular season, Thomas Harding of MLB.com reports.

EDGE Analysis

The young right-hander was already prepared to miss the first few games, but this move will ultimately allow the team to keep a fresh arm on the roster in his stead. No word has come forth as to how soon he'll be back in action. This will open the door for Scott Oberg and Antonio Senzatela to start the season in the major-league bullpen.

Estevez (oblique) will not be ready for Opening Day after experiencing a setback in his rehab program, Thomas Harding of MLB.com reports.

EDGE Analysis

The young reliever tweaked his oblique back in February, but he still hasn't been able to ramp up his throwing enough to return to game action. He still doesn't expect to be out for an extended period of time, but no firm timetable for his return has emerged at this point. Scott Oberg, Jairo Diaz and Zac Rosscup could see more innings out of the bullpen while Estevez is sidelined.

Manager Bud Black said that Estevez (oblique) is progressing well and could get into a Cactus League game soon, Thomas Harding of MLB.com reports.

EDGE Analysis

The reliever has been sidelined in late February despite originally having a return timetable of just 5-to-7 days. Oblique injuries can prove to linger longer than expected though, so it's not too surprising to see the Rockies taking things slowly with him. Estevez should be back relatively soon, but it's unclear if he'll build up enough innings to be ready for Opening Day. The 25-year-old made just one spring appearance prior to getting injured.

Estevez tweaked his left oblique and will be sidelined for 5-to-7 days, Patrick Saunders of The Denver Post reports.

EDGE Analysis

Estevez sustained the injury over the weekend, and though he noted it wasn't anything major, he's still expected to miss some time in order to allow the issue to fully recover. The 25-year-old, who posted a 5.57 ERA and 1.64 WHIP across 32.1 innings of work last season, is looking to lock down a low-leverage bullpen job during spring training.

Estevez is unavailable to pitch due to muscle soreness on his left side, Thomas Harding of MLB.com reports.

EDGE Analysis

It appears that Estevez tweaked a muscle in his side during Friday's game, during which he pitched one scoreless inning. The injury isn't seen as anything major, but the Rockies are going to be cautious with Estevez and plan to rest him for a few days. More information about his eventual return should be available in the near future.

Estevez finished the regular season with a 5.57 ERA, a 1.64 WHIP and an 8.6 K/9 in 32.1 innings pitched.

EDGE Analysis

The young right-hander performed well after his September callup, producing a 9.3 K/9 in 11.2 innings of work and throwing eight straight scoreless appearances to close out the campaign. At just 24 years old, Estevez has the stuff to be a future closer for the Rockies, but he needs to control his offerings better before the Rockies let him go anywhere near high-leverage innings again.

Estevez was promoted by the Rockies on Friday.

EDGE Analysis

Estevez joins the wave of September call-ups for Colorado, and will join the team ahead of this weekend's series with the Diamondbacks. During 21 appearances with the big-league club this season, Estevez has posted a 6.53 ERA and 1.69 WHIP, and is unlikely to be deployed in any high-leverage situations out of the bullpen.

Estevez was optioned to Triple-A Albuquerque prior to Monday's game against the Braves.

EDGE Analysis

The Rockies needed to clear room on the roster for Monday's starter, Chad Bettis, and Estevez was the resulting roster casualty. He pitched solid in his most recent stint with the big club, registering four scoreless innings to help lower his ERA to 6.53 on the season. He'll continue to provide organizational relief depth now that he's back in Triple-A.

Estevez was recalled from Triple-A Albuquerque on Saturday.

EDGE Analysis

He has been up and down from Triple-A to the big leagues this season, and despite owning an 8.10 ERA in 16.2 innings in the majors this season, his 3.03 FIP and 18 strikeouts suggest he could be much more reliable going forward. Look for him to work primarily in low-leverage spots.

Estevez was returned to Triple-A Albuquerque following Sunday's doubleheader with the Nationals.

EDGE Analysis

The Rockies brought Estevez in from the minor-league ranks to serve as their 26th man in the twin bill, but the right-hander ended up going unused out of the bullpen in both contests. He'll head back to Albuquerque to continue serving as organizational relief depth. He's been one of the better arms out of the Triple-A bullpen this season, turning in a 1.78 ERA and 23 strikeouts in 25.1 innings.
