The Orioles selected Weston's contract from Triple-A Norfolk on Thursday, Andy Kostka of TheBanner.com reports.

Weston has excelled at collecting strikeouts in the minors this season, fanning 40 batters in just 27.1 innings, but he's struggled to limit runs while posting a 6.26 ERA and 1.70 WHIP. Despite his poor effectiveness, the Orioles will add him to their big-league roster and likely deploy him as a multi-inning reliever. Trey Gibson was optioned to Norfolk in a corresponding move.

The Orioles optioned Gibson to Triple-A Norfolk on Thursday, Andy Kostka of TheBanner.com reports.

Gibson gave the Orioles 5.2 innings of one-run ball during his season debut in Wednesday's win. Now that his duties as a spot starter are complete, he'll head back to Triple-A in favor of Cameron Weston. Gibson owns a 3.65 ERA and 1.62 WHIP across 12.1 innings through his first three MLB appearances and figures to remain a candidate for additional spot starts throughout the season.

Pirates manager Don Kelly said Thursday that Mlodzinski has been moved to the bullpen, Jason Mackey of MLB.com reports.

Mlodzinski has held his own as a member of the Pirates rotation this season, collecting a 3.76 ERA, 1.42 WHIP and 46:20 K:BB over 55 innings. However, with the right-hander having significant relief experience and the Pirates needing bullpen help from the right side, it makes sense to shift Mlodzinski to a relief role to accommodate the return of Jared Jones (elbow), who will be activated from the 60-day injured list to start Friday's game against the Twins.

Pirates manager Don Kelly said Thursday that Jones (elbow) will return from the 60-day injured list and start Friday's game against the Twins at PNC Park, Jason Mackey of MLB.com reports.

Jones will be making his first appearance at the big-league level since he underwent UCL surgery last May. The right-hander looked sharp in five rehab starts, logging a 2.89 ERA, 1.02 WHIP and 24:6 K:BB across 18.2 innings. He went 4.1 frames and threw 76 pitches in his most recent outing with Triple-A Indianapolis last weekend, so while Jones should be able to reach five innings Friday if he pitches efficiently, he shouldn't be expected to work much longer than that. Expect the Pirates to manage Jones' workload after he missed all of the 2025 campaign.

Castillo is slated to work out of the bullpen and will piggyback starter Bryce Miller during Sunday's game against the Diamondbacks in Seattle, Adam Jude of The Seattle Times reports.

Though both Castillo and Miller have expressed a reluctance to being used in a piggyback arrangement, the two pitchers will nonetheless operate in a tandem for a third consecutive turn through the rotation. The setup worked well the last time out Monday in Sacramento, with Castillo starting the game and delivering one of his better efforts of the season, as he struck out six and allowed just two hits and two walks over four scoreless frames. Miller followed with five innings of two-run ball and was credited with the win, but Castillo should have better odds of factoring into the decision Sunday while he and Miller are used in the opposite order. The Mariners will reassess their rotation plans after Sunday's contest, and Castillo may need another strong showing against Arizona to ensure that he avoids moving into a full-time relief role.

Miller is scheduled to start Sunday's game against the Diamondbacks in Seattle and will be used in tandem with Luis Castillo, Adam Jude of The Seattle Times reports.

Though both Miller and Castillo have expressed displeasure with being deployed in a piggyback arrangement, the two pitchers will nonetheless operate in a tandem for a third consecutive turn through the rotation. The setup worked well the last time out Monday in Sacramento, with Castillo delivering four shutout frames to open the game before Miller followed with four strikeouts over five innings of two-run ball en route to picking up his first win of the season. The two will pitch in the opposite order Sunday, and while being piggybacked by Castillo will likely suppress MIller's workload, the latter should still be able to reach the five innings he would need to hit to qualify for a win in a starting role. Since being activated from the injured list May 13, Miller has covered between five and 5.2 innings and 72 and 83 pitches over his three appearances while posting a 2.55 ERA and 1.00 WHIP.

Woods Richardson will start Thursday's game versus the White Sox in place of the injured Kendry Rojas (elbow), Betsy Helfand of the St. Paul Pioneer Press reports.

Rojas had to be scratched because of a sore pitching elbow. Woods Richardson's last two appearances both came in relief, and he will be starting on just two days' rest after throwing 35 pitches over two frames Monday against Chicago. The right-hander's last start came more than two weeks ago, and he will be facing a restricted workload versus the White Sox.

Bubic (elbow) is still dealing with general left arm fatigue, MLB.com reports.

Bubic began a throwing program this past weekend and continues to play catch despite not yet feeling 100 percent. The southpaw will not be allowed to ramp things up until he's no longer feeling fatigue in his pitching arm, so there remains no timetable for Bubic's return to the Royals' rotation. He posted a 4.11 ERA, 1.23 WHIP and 51:26 K:BB across 50.1 innings before landing on the 15-day injured list with left elbow discomfort in mid-May.

Skubal (elbow) will throw another simulated game Monday at Tropicana Field, Evan Woodbery of MLive.com reports.

Skubal tossed 39 pitches over 2.2 innings in a simulated game Tuesday and will build up further Monday. Tigers manager A.J. Hinch said Thursday that Skubal's next throwing session after Monday's will occur June 7. Woodbery speculates that it could line Skubal up to make a rehab start June 12 before rejoining the Tigers' rotation June 17 in Houston, though nothing is official on that front at this point.

Priester (shoulder) recorded two outs and was charged with three earned runs on two hits and three walks Wednesday in his rehab start with Triple-A Nashville. He struck out one batter.

Per Adam McCalvy of MLB.com, Milwaukee was aiming for Priester to cover five innings and around 80-to-85 pitches Wednesday in his third start since resuming his rehab assignment, but the right-hander fell well short of both benchmarks. He needed 38 pitches just to record his two outs, with Priester's erratic control prompting his removal from the game before the first inning concluded. Priester hasn't looked sharp at any point over the course of his two separate rehab assignments spanning six starts, accruing a 21.60 ERA, 3.60 WHIP and 10:17 K:BB in 10 innings over one outing with High-A Wisconsin and five with Nashville. In addition to lacking control, Priester has struggled to regain velocity as he works his way back from right neurogenic thoracic outlet syndrome. Priester averaged 93.9 mph with his sinker during the 2025 season, but he reached a max velocity of just 93.3 mph during Wednesday's start.
