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.

Blue Jays manager John Schneider said Friday that Bieber (elbow) will likely make another rehab start with Triple-A Buffalo before rejoining Toronto, Ben Nicholson-Smith of Sportsnet.ca reports.

Bieber looked sharp in his second rehab start Thursday, tossing six scoreless innings while allowing five hits and a walk with five strikeouts. If the veteran right-hander needs another turn in Triple-A and all goes well, then he could be available to return for the Blue Jays' series opener against the Astros on Monday, June 22. Bieber's return would likely result in Patrick Corbin being removed from the Blue Jays' rotation.

The Royals placed Lugo on the 7-day concussion list Friday.

Lugo was struck in the forehead by a line drive during Wednesday's game against the Rangers. The good news for Lugo was that a subsequent CT scan came back negative, but he's now in the league's concussion protocol and will need to hit multiple checkpoints before being cleared to return to the majors. In a corresponding move, the Royals recalled Eli Morgan from Triple-A Omaha.

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.

Tigers manager A.J. Hinch confirmed Friday that Mize (adductor) will rejoin the rotation with a start Sunday in Cleveland, Evan Woodbery of MLive.com reports.

Mize has been out since late May with right adductor inflammation, but he's ready to roll after tossing five frames of one-run ball with five strikeouts in his lone rehab start with Single-A Lakeland on Tuesday. He threw 55 pitches Tuesday and hasn't had a full workload in three weeks, so Mize might not pitch deep into Sunday's contest.

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 Guardians recalled Espino from Triple-A Columbus on Friday, Tim Stebbins of MLB.com reports.

Espino was one of the top pitching prospects in all of baseball a few years ago, but his career has been sidetracked by injuries, including a pair of shoulder surgeries. He's moved to the bullpen this season and has finally earned a call-up after collecting a 5.30 ERA and 29:15 K:BB over 18.2 innings with Columbus.

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.
