Arrighetti will receive a second opinion on his injured right elbow this week, Chandler Rome of The Athletic reports.

Arrighetti told reporters last week that his UCL was intact and he would not require surgery. That's presumably still the case, but more should be known about his course of treatment after he receives a second opinion. Arrighetti has been out for all of September and is not expected back before the end of the regular season.

Walter will undergo surgery on his left elbow this week, Chandler Rome of The Athletic reports.

The specifics on the nature of the procedure aren't clear, but more should be known after the surgery takes place. Walter was terrific this season when healthy for the Astros, collecting a 3.35 ERA and 52:4 K:BB over 53.2 innings covering nine starts. If it's UCL surgery that the 29-year-old needs, he would likely be out until the 2027 season.

The Astros recalled France from Triple-A Sugar Land on Tuesday.

France allowed one run over five innings in his last start at Sugar Land. He had pitched in relief in his three appearances prior to that, and the Astros plan to deploy him as a multi-inning reliever.

Orioles interim manager Tony Mansolino said that Kremer (forearm) played catch Sunday and will do so again Tuesday, Jake Rill of MLB.com reports.

Kremer was removed from his start in Friday's 2-1 win over the Dodgers after three innings due to right forearm soreness. An MRI came back clean, and while he will miss his next turn in the rotation, the hope remains that Kremer could avoid a stint on the 15-day injured list.

Kolek is slated to start Thursday's game against the Guardians at Progressive Field.

With Seth Lugo (back) recently joining Cole Ragans (shoulder) on the injured list, Kolek will stick around with the Royals to make a second turn through the rotation following his call-up from Triple-A Omaha last Thursday. During his start in this past Saturday's 11-2 win over the Twins, Kolek went seven strong innings and struck four batters while permitting two earned runs on six hits and one walk. He now maintains a respectable 3.88 ERA over 92.2 innings between San Diego and Kansas City, though it's supported by a weak 9.3 K-BB%.

The Astros are expected to recall France from Triple-A Sugar Land during their series in Toronto that runs through Thursday, Chandler Rome of The Athletic reports.

France's last appearance with Sugar Land was a start, but his three outings prior to that came out of the bullpen, and he's expected to fill a multi-inning relief role with Houston. The right-hander missed the first half of this season while recovering from shoulder surgery and holds a 6.38 ERA and 23:20 K:BB over 24 innings during his time with Sugar Land.

Sugano said Tuesday that his right foot hasn't swelled up as much as anticipated, and he expects to be ready to make his next scheduled start, Roch Kubatko of MASNSports.com reports.

Sugano was lifted from Sunday's 5-2 loss to the Dodgers after being struck on the foot by a comebacker, but the injury doesn't look like it will cost him any additional time. The right-hander is tentatively schedule to start Sunday's game in Toronto.

Harrison is headed to Sacramento to join the Red Sox and could be recalled from Triple-A Worcester prior to Wednesday's game against the Athletics, Tommy Cassell of the Worcester Telegram & Gazette reports.

The Red Sox have not yet announced a starter for Wednesday's game, though manager Alex Cora said that lefty Payton Tolle is expected to be used in some capacity. Harrison could also be in the mix, perhaps in a tandem start with Tolle. The left-handed Harrison pitched one inning with Triple-A Worcester on Sunday after overcoming an ankle injury, so he would be pitching on two days' rest Wednesday. Harrison holds a 3.75 ERA and 50:27 K:BB over 50.1 innings with Worcester since the Red Sox acquired him from the Giants on June 15.

Urquidy (elbow) is set to make one more rehab appearance for Triple-A Toledo on Tuesday or Wednesday before being evaluated for a potential return, MLB.com reports.

Urquidy has already made a total of nine rehab appearances, including five with the Mud Hens. The veteran righty looked sharp in his last two outings, logging a total of six scoreless innings with six strikeouts. Urquidy, who is working his way back from June 2024 Tommy John surgery, last pitched in the majors in 2023, so the Tigers are likely to be very cautious with his return. He'll likely slot into a bullpen role to close out this season, though he figures to compete for a 2026 rotation spot next spring.

Oakie has 22 strikeouts over 9.1 scoreless innings in his last two starts for Single-A Lynchburg.

Oakie has raised his stock as much as any lower-level prospect over the past few weeks, as he has shown monster stuff at the end of an up-and-down season. His upper-90s fastball can be borderline unhittable when he's locating it, and he compliments it with a plus hard slider. He received a $2 million bonus after the Guardians selected him with the No. 84 overall pick last year. Oakie has a 14 percent walk rate and 1.53 WHIP on the year, so there is plenty of reliever risk to go with a sky-high ceiling if he can stay healthy and continue refining his craft. He doesn't turn 20 until May.
