Astros manager Joe Espada said they are still waiting on Arrighetti's (elbow) MRI results Thursday, but that a return during the regular season is unlikely, Matt Kawahara of the Houston Chronicle reports.

Arrighetti was placed on the 15-day injured list Wednesday due to right elbow inflammation. He's without a clear timeline for his return but isn't likely to be back with the Astros in the final weeks of the regular season.

The Royals placed Lugo on the 15-day injured list Thursday with a lower-back strain, Anne Rogers of MLB.com reports.

The Royals originally planned to push Lugo's next start back to Saturday after he reported tightness in his lower back. However, he didn't feel any improvement while playing catch Thursday and will now spend the next couple of weeks on the shelf in order to get back to 100 percent. Stephen Kolek was recalled from Triple-A Omaha in a corresponding move and is expected to start Saturday's game against the Twins.

The White Sox recalled Cannon from Triple-A Charlotte on Thursday.

Cannon is scheduled to serve as the bulk reliever in Thursday's game against the Twins. The right-hander has made 17 starts and two relief appearances for Chicago this season, posting a 5.34 ERA and 76:35 K:BB over 96 innings.

Ragans (shoulder) threw a 30-pitch live batting practice session Wednesday, MLB.com reports.

Ragans' recovery from a torn left rotator cuff has been slow and deliberate, with Wednesday marking his first time facing live hitters since he was placed on the injured list June 11. While no firm timeline has been set for Ragans' return, the next step for the 27-year-old would likely be heading out on a rehab assignment to build up his pitch count with the hope of rejoining the big club in the second half of September.

Hess has a 3.16 ERA, 0.97 WHIP and 32:10 K:BB in 25.2 innings across five starts for Double-A Somerset.

The Yankees selected Hess with the 26th pick in the 2024 First-Year Player Draft and he has logged 20 starts and 92.1 innings thus far in his first pro season. Hess, who was promoted from High-A Hudson Valley to Double-A on Aug. 5, has a strong 33.2 percent strikeout rate on the year, but his 11.3 percent walk rate is a tad high. Hess has a couple plus pitches in his mid-90s fastball and mid-70s curveball while his slider and changeup lag behind. He should spend the bulk of 2026 at Triple-A, but a summer promotion to the big leagues is in play if Hess picks up where he left off this season.

Warren allowed two runs on five hits and no walks while striking out four batters over five-plus innings in a no-decision against Houston on Wednesday.

Warren had a 4-1 lead heading into the sixth, but he was pulled after giving up a leadoff homer to Jeremy Pena in that frame. New York's bullpen went on to allow the Astros to eventually take the lead, preventing Warren from earning his second straight win. Still, this was a promising result for the right-hander, who has given up two or fewer runs in seven of his past eight starts. He has a 2.79 ERA during that span, lowering his overall mark to 4.28 on the season.

Alexander allowed three runs on six hits and two walks while striking out six batters over five innings in a no-decision against the Yankees on Wednesday.

Alexander wasn't dominant Wednesday, and all three runs he allowed scored on a pair of Yankees homers. Nonetheless, he kept Houston within arm's length, which proved critical when the Astros mounted a comeback over the sixth through eighth frames. Alexander has now given up three or fewer runs in seven straight outings, posting a 2.79 ERA and 1.11 WHIP with a 38:10 K:BB across 38.2 innings during that span. That's earned him a spot in the rotation for now, while Lance McCullers has been moved to the bullpen.

Springs (10-10) took the loss against St. Louis on Wednesday, allowing two runs on five hits and one walk while striking out four batters over six innings.

Springs pitched well Wednesday, giving up just a single run in each of the third and seventh innings, However, the Athletics' offense wasn't able to put its only run on the board until the eighth frame. Despite the defeat, Springs managed his first quality start since Aug. 6 and notched a healthy 10 whiffs. He's slated for a home matchup against Boston his next time out.

Bergert didn't factor into the decision against the Angels on Wednesday, allowing one run on one hit and three walks while striking out six over five innings.

The right-hander was in control for most of the outing, allowing just three baserunners through five frames before exiting after issuing a walk to Zach Neto to lead off the sixth. That runner later came around to score on a Jo Adell homer, leaving Bergert with his lone earned run. Since joining the Royals, Bergert has been remarkably steady, not allowing more than two runs in any of his starts while completing at least five innings in each. Over that stretch, the 25-year-old has posted a 2.43 ERA with a 31:11 K:BB through 33.1 innings, and his next turn against Cleveland presents another favorable matchup given the Guardians' offensive struggles.

Gomez didn't factor into the decision Wednesday against Minnesota, allowing one run on seven hits and one walk in five innings. He struck out five.

Gomez has done some quality work since joining Chicago's rotation, as Wednesday's showing was his third start where he's surrendered one run or no runs. The 25-year-old right-hander tossed a season-high 94 pitches in what was his fifth start of the year, so he's certainly built up to handle a traditional starter's workload to wrap up the campaign. Gomez has a 3.42 ERA, 1.31 WHIP and 27:12 K:BB over 23.2 innings as a starter for the White Sox, and he's next scheduled to take the mound at home against the Rays.
