The Rockies optioned Peralta to Triple-A Albuquerque on Friday.

Peralta was promoted from Triple-A on Sunday and gave up a solo homer while striking out three batters across two innings during his lone outing with the big club. He'll now end up as the roster casualty necessary to make room for Sean Sullivan, who was called up to start Friday's contest.

The Rockies selected Sullivan's contract from Triple-A Albuquerque ahead of his start Friday against the Athletics.

Sullivan will be making his MLB debut Friday, though he will be doing so in a very hitter-friendly environment at Las Vegas Ballpark after posting a 5.76 ERA and 1.57 WHIP in 54.2 innings at Triple-A, making him a less-than-desirable fantasy option. Sammy Peralta was optioned to Albuquerque to make room for Sullivan on the active roster, and Chase Dollander (elbow) was moved to the 60-day IL to free up a 40-man spot.

Mets manager Carlos Mendoza said Friday that Senga (spine/arm) will require at least one more minor-league rehab start before the organization considers activating him from the 15-day injured list, Anthony DiComo of MLB.com reports.

The right-hander had his rehab outing pushed back early this week due to ulnar nerve irritation in his right arm, but he was able to take the mound with Double-A Binghamton on Thursday and gave up just one run across six innings. Senga built up to 75 pitches in that start, so he's already most of the way to a full starting workload and could re-enter the Mets' rotation with another solid showing in the minor leagues.

The Cardinals optioned Dobbins to Triple-A Memphis on Friday, Derrick Goold of the St. Louis Post-Dispatch reports.

Dobbins made a couple long-relief appearances and one start for the Cardinals during his stint in the majors. The club had left open the possibility of sticking with Dobbins as part of a six-man rotation for at least another turn, but ultimately it opted to revert back to a five-man setup. Dobbins holds a 3.63 ERA, 1.38 WHIP and 19:7 K:BB across 17.1 innings in the majors this season.

Atlanta activated Waldrep (elbow) from the 60-day injured list Friday and subsequently optioned him to Triple-A Gwinnett.

The right-hander has been working his way back from offseason elbow surgery and made his third minor-league rehab start Thursday -- surrendering four runs across 3.2 innings with Double-A Columbus -- so it's an interesting decision by Atlanta to activate him now rather than simply continuing his rehab assignment in the minors. Waldrep posted a 2.88 ERA, 1.19 WHIP and 55:22 K:BB across 56.1 regular-season frames in the big leagues last year and should get another look with Atlanta at some point this summer.

Painter will be used in a bulk-relief role Friday in Milwaukee, Adam McCalvy of MLB.com reports.

Painter had one other bulk-relief appearance this season and fared well, striking out seven while holding the Diamondbacks to one run over five innings. He will be preceded by opener Tanner Banks.

The Rockies will call up Sullivan from Triple-A Albuquerque to make his major-league debut with a start Friday versus the Athletics, Kevin Henry of The Denver Gazette reports.

It's a difficult environment for Sullivan to be making his big-league debut, as Friday's contest will be played at the very hitter-friendly Las Vegas Ballpark. The 23-year-old southpaw holds a 5.60 ERA and 50:19 K:BB over 54.2 innings covering 11 starts this season with Albuquerque. Sullivan could earn additional starts if he pitches well, but he's not a recommended fantasy option Friday.

Crow permitted one hit and one walk over two scoreless innings of relief Tuesday in the Brewers' 7-5 loss to the Athletics.

After he had made his first four big-league appearances as a starter, Crow shifted to the bullpen this week while Milwaukee elected to move forward with Robert Gasser and Shane Drohan as the back-end members of the five-man rotation. Though Crow fared well in his first relief outing, the Brewers aren't likely to pull the plug on developing him as a starter just yet. With that in mind, Crow could sent back to Triple-A Nashville in the near future so that he can continue working out of the rotation.

The Pirates recalled Kelly from Triple-A Indianapolis on Friday, Colin Beazley of the Pittsburgh Post-Gazette reports.

Kelly has logged a 4.50 ERA, 1.48 WHIP and 47:24 K:BB across 54 innings with Indianapolis this season. He's been used mostly as a starting pitcher with Indianapolis, but the Pirates will break him in at the major-league level as a reliever.

Dobbins did not factor into the decision in Thursday's 5-4 loss to the Mets, allowing three runs on seven hits over 4.1 innings. He struck out five without walking a batter.

The Mets got to Dobbins early, scoring three runs on a pair of first-inning homers by Bo Bichette and Jared Young, but the right-hander would manage to settle in and hold New York scoreless over his final 3.1 frames. Dobbins has made two starts and four appearances overall for St. Louis this season, posting a 3.63 ERA with a 1.38 WHIP and 19:7 K:BB across 17.1 innings. He would currently line up to face the Padres at home in his next outing, assuming the Cardinals stick with a six-man rotation.
