The Nationals recalled Cavalli from Triple-A Rochester ahead of his scheduled start Wednesday against the Athletics in Washington.

Cavalli will return to an MLB mound for the first time since Aug. 26, 2022, after he underwent Tommy John surgery the following spring and then struggled to regain form in the minors upon completing his recovery from the procedure. The right-hander looked sharper over his last four starts with Rochester -- he produced a 5.75 ERA and 1.52 WHIP but a sparkling 25:6 K:BB in 20.1 innings -- and could now get the chance to stake a permanent claim to a spot in the big-league rotation after the Nationals shipped Michael Soroka to the Cubs last week. Cavalli gets a tough draw Wednesday, taking on an Athletics squad that has produced a 107 wRC+ versus righties this season while also pitching at one of the more favorable MLB venues for hitters in Nationals Park.

Astros manager Joe Espada said Wednesday that Javier (elbow) is in position to make his season debut with the major-league club during its homestand next week, Chandler Rome of The Athletic reports.

Javier made his fifth and likely final rehab start Tuesday with Triple-A Sugar Land, allowing one run one two hits and four walks while striking out six over 3.2 innings. The right-hander holds a 5.14 ERA and 15:15 K:BB over 14 frames during his rehab assignment and reached 77 pitches Tuesday. Javier could rejoin the Astros' rotation as soon as Monday against the Red Sox. While he makes for a viable stash in fantasy leagues, it might be wise to leave him on your bench initially.

Weathers (lat) threw a bullpen session Wednesday, Christina De Nicola of MLB.com reports.

The workout appeared to mark Weathers' first time throwing off a mound since he landed on the 60-day injured list in early June with a left lat strain. After being sidelined for a lengthy period of time, Weathers will need time to be built back up. A return before the end of August seems unlikely, but manager Clayton McCullough said Wednesday that he's "cautiously optimistic" that Weathers will pitch again for the big club this season, per Alex Krutchik of FishOnFirst.com.

The Astros optioned Blubaugh to Triple-A Sugar Land on Wednesday.

The transaction comes one day after Blubaugh picked up his first major-league victory, allowing two runs over five frames against the Marlins in a bulk-relief appearance. Blubaugh will rejoin the rotation at Sugar Land and could get another opportunity in the big leagues later this season if the Astros need a starter.

The Astros activated Arrighetti (thumb) from the 60-day injured list ahead of his scheduled start Wednesday in Miami.

The right-hander wound up missing almost exactly four months after suffering a fractured right thumb back in early April. Prior to being activated, Arrighetti held a 5.73 ERA and 11:5 K:BB in 11 innings over three rehab starts between Double-A Corpus Christi and Triple-A Sugar Land. He threw 79 pitches in his final rehab outing with Sugar Land last Thursday, so he'll be in line for a somewhat limited workload Wednesday.

Reds manager Terry Francona said Wednesday that Miley (forearm) will face hitters Friday, Casey Drottar of MLB.com reports.

It will be the first time Miley has faced live hitters since he went down with a left flexor strain in late June. Miley will be eligible for activation from the 60-day injured list Aug. 16, and he could be ready to return then or shortly thereafter. That said, there's no guarantee the Reds will have a role available for Miley at that time.

Tong struck out eight while allowing three hits and two walks over five scoreless innings for Double-A Binghamton on Tuesday.

The 22-year-old right-hander has absolutely nothing left to prove in the Eastern League. Tong hasn't served up a home run since late May, and over 53 innings since the beginning of June he sports a 1.02 ERA, 0.83 WHIP and 82:20 K:BB. The minor-league strikeout leader with 154 punchouts in 97 innings on the season, Tong should be getting a promotion to Triple-A any day now, especially with the trade of Blade Tidwell to the Giants having opened up a spot in the Syracuse rotation.

Lorenzen (oblique) allowed four runs on four hits and three walks over three innings Tuesday with Double-A Northwest Arkansas. He struck out five.

Lorenzen struggled in his first rehab outing Tuesday, surrendering two home runs -- including one to top prospect Walker Jenkins -- as he works his way back from a left oblique strain. Prior to the injury, the veteran had been serviceable but unspectacular, compiling a 4.61 ERA and 1.30 WHIP across 99.2 innings in 18 starts. The Royals' rotation remains unsettled with Kris Bubic (shoulder) out for the year and Cole Ragans (shoulder) also sidelined, leading to the recent additions of Bailey Falter and Ryan Bergert, both of whom have already made their team debuts. Lorenzen's role once he's fully healthy will be an interesting storyline to track.

Phillies manager Rob Thomson said that Wheeler's next start will be pushed back from Friday to Sunday in Texas while the right-hander manages shoulder stiffness, Matt Gelb of The Athletic reports.

Wheeler felt some stiffness following his most recent start in Saturday's 7-5 loss to the Tigers. He was sent for an MRI -- which came back negative -- and the hurler was able to play catch Wednesday. The Phillies don't appear concerned that the shoulder could be a lingering issue for Wheeler, but fantasy managers should nonetheless keep a eye on news pertaining to the 35-year-old leading up to Sunday. Assuming he makes it through his between-starts bullpen session without issue, Wheeler isn't expected to face any restrictions Sunday.

Double-A Chesapeake reinstated Pham (forearm) from the 7-day injured list Tuesday.

Pham will likely slot back into the Chesapeake rotation in the coming days after he completed a two-start rehab assignment and most recently tossed 3.1 scoreless innings for High-A Aberdeen on Saturday. The right-hander previously turned in a 3.42 ERA, 1.18 WHIP and 35:9 K:BB across 23.2 innings in five appearances for Chesapeake before landing on the shelf in early May due to forearm inflammation.
