The White Sox promoted Schultz from Double-A Birmingham to Triple-A Charlotte on Saturday, Kyle Williams of the Chicago Sun-Times reports.

Though Schultz has struggled with his control in the minors this season, posting a 14.4 percent walk rate and 1.57 WHIP over 61.2 innings, he's managed a 3.06 ERA and has struck out 63 batters in Double-A ball. That's good enough to earn him a promotion to the top level of the minors, moving him a step closer to making his major-league debut. Schultz is one of the league's top lefty pitching prospects and could reach the majors before the end of the current campaign if he fares well with Charlotte.

Rocker is with the Rangers in Texas and could be asked to start Sunday versus the White Sox if Tyler Mahle (shoulder) is unable to pitch, Kennedi Landry of MLB.com reports.

Though Rocker is with the team, no roster move has been made, so for now he is a contingency plan. Mahle felt some shoulder soreness during his most recent start Tuesday, but it's not yet clear if the issue is serious enough to prevent him from making his scheduled start Sunday. If Rocker is ultimately recalled to start, it would be his first appearance with the big club since he gave up five runs over 3.1 innings in a loss against Tampa Bay on June 4.

Mahle is dealing with a sore right shoulder ahead of his scheduled start against the White Sox on Sunday, per Kennedi Landry of MLB.com.

Rangers manager Bruce Bochy said Saturday that Mahle felt some soreness in his shoulder during his most recent start Tuesday against Minnesota, during which the right-hander gave up four runs over 5.2 innings. It's not yet clear if Mahle will miss Sunday's start versus Chicago due to the issue, but Kumar Rocker is with the Rangers in Texas and could be called upon if Mahle is unable to take the mound.

The White Sox added Civale to their active roster Saturday.

Civale was acquired by Chicago in a trade with Milwaukee on Friday. He's slated to make his White Sox debut as a starter Sunday versus Texas. To make room for Civale on the 26-man roster, lefty reliever Tyler Gilbert was optioned to Triple-A Charlotte.

Houston transferred Arrighetti to the 60-day injured list Saturday, Brian McTaggart of MLB.com reports.

Arrighetti broke his right thumb after being hit by a ball during batting practice in early April and had been on the 15-day IL since. The move to the 60-day IL doesn't affect the hurler's timeline to return -- early July remains a best-case scenario -- but it does open a spot on the team's 40-man roster. Arrighetti will likely need a minor-league rehab stint before he's ready to rejoin Houston's rotation.

Scherzer (thumb) tossed 4.1 innings in a rehab start with Triple-A Buffalo on Friday, allowing two runs on four hits and no walks while striking out four batters.

This was Scherzer's first time pitching in a game since March 29. The veteran hurler landed on the IL due to a right thumb injury shortly after that contest -- his lone regular-season appearance this year -- and had his recovery temporarily stalled by a back injury, but he's now seemingly past the latter issue. Scherzer threw 56 pitches (39 strikes) in Friday's rehab start and sat at 91.9 mph with his fastball, per Shi Davidi of Sportsnet.ca. He'll likely need at least one more rehab appearance before he's ready to make his return to Toronto's rotation.

Bieber (elbow) received good news Friday from the doctor that performed his Tommy John elbow surgery, Josh Kirshenbaum of MLB.com reports. Dr. Keith Meister told Bieber his discomfort was normal and not structural.

Bieber had his rehab assignment paused after feeling discomfort in his elbow, All the tests the right-hander went through came back with good news, and the next step is to resume throwing. The Guardians have not yet established a program, but Bieber will likely throw at least one bullpen session before resuming his rehab assignment.

Dobbins will start Saturday's game against the Yankees at Fenway Park, Gabrielle Starr of the Boston Herald reports.

Dobbins will receive his second straight start after he was moved from the bullpen last week to join the rotation as a replacement for Richard Fitts, who was optioned to Triple-A Worcester. Though he failed to record a strikeout in his latest outing Sunday at Yankee Stadium, Dobbins picked up a win while holding a tough New York lineup to three earned runs on four hits and no walks over five innings. Dobbins will head into Saturday's rematch with the Yankees with a 4.20 ERA, 1.28 WHIP and 37:10 K:BB in 49.1 innings over his 10 appearances (eight starts) with the Red Sox this season.

Vasil is slated to start Saturday's game against the Rangers in Arlington.

Vasil will make his second straight start and his third turn in a row through the rotation after making a bulk-relief appearance June 4, but he could soon be headed back to the bullpen. With the acquisition of Aaron Civale on Friday, the White Sox now have six starters, and the rotation will become more crowded once Jonathan Cannon (back) returns from the injured list. Vasil has yet to work more than four innings in an appearance this season, but he's recorded between nine and 11 outs in each of his last four outings.

Wacha (3-6) took the loss Friday, giving up five runs on nine hits and two walks over 5.1 innings as the Royals fell 6-4 to the A's. He struck out five.

The right-hander kept things close through five innings despite serving up solo shots to Austin Wynns and Luis Urias amid a barrage of singles, but Wacha gave up two more knocks with one out in the sixth and watched both runners come around to score after he'd gotten the hook. Wacha has gone five straight starts without getting into the win column, but his 4.13 ERA, 1.27 WHIP and 23:5 K:BB through 28.1 innings during that stretch suggest the issue has more to do with the Royals' offense than his own performance. He'll look to end that drought in his next outing, which is scheduled to come on the road next week against the Rangers.
