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.

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.

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.

Severino (6-11) earned the win Tuesday over the Nationals, allowing three runs on five hits and two walks while striking out five in six innings.

Severino reeled off his fourth straight win after he picked up just one win over eight starts from June 2 through July 11. He tossed three scoreless and was already staked a nine-run lead in the fourth by the time the Nationals finally pushed a run across. Severino has reached six innings in two of his past three starts after doing so only one time in nine starts prior. He lines up to complete a strong two-start week on the road this weekend against the Orioles.

Ohl will start Wednesday's contest in Detroit, Evan Woodbery of MLive.com reports.

Ohl will be pitching on three days' rest after making a three-inning relief appearance Saturday in Cleveland. The 25-year-old also hasn't thrown more than four innings at the major- or minor-league level in 2025, so he's unlikely to pitch deep into Wednesday's game. Ohl has permitted five runs with a 6:2 K:BB over six innings in two appearances (one start) with the Twins this season.

Allen came away with a no-decision in Tuesday's 3-2 win over the Mets, giving up two runs on four hits and four walks over five innings. He struck out six.

The lefty's control was a little wobbly, as he threw just 51 of 88 pitches for strikes and managed first-pitch strikes to only 12 of the 23 batters he faced, but despite dealing with traffic on the bases in all five of his innings, Allen was able to limit the damage. He's been a steady presence in the Guardians' rotation, lasting at least five innings in 11 straight starts since the beginning of June while posting a 3.90 ERA, 1.21 WHIP and 49:19 K:BB over 64.2 innings. Allen will look for his eighth win of the season in his next trip to the mound, which lines up to come at home early next week against the Marlins.

Crochet (13-4) picked up the win in Tuesday's 6-2 victory over the Royals, giving up two runs on four hits and a walk over seven innings. He struck out eight.

The southpaw racked up 34 called or swinging strikes among his 105 pitches (66 total strikes) as he delivered his fourth straight quality start and 15th of the season. Crochet leads the American League in wins and strikeouts (183) while sitting second behind Tarik Skubal in ERA (2.18 to 2.24), putting him firmly in the Cy Young conversation. The Red Sox ace is scheduled to make his next outing on the road early next week in Houston.

Kremer (8-8) took the loss Tuesday against the Phillies, allowing four runs on eight hits and a walk while striking out six in six innings.

Four of the eight hits allowed by Kremer went for extra bases, including a two-run homer in the second inning by Max Kepler. Still, Kremer was able to settle in thereafter, allowing one run over his final four innings. He's now pitched at least five frames in all but three of his 23 appearances this season and has become a reliable innings eater for the Orioles this season. Kremer owns a 4.35 ERA, 1.28 WHIP and 110:35 K:BB in 132.1 innings and lines up for a home meeting with the Mariners next week.

Bergert (1-1) took the loss Tuesday, giving up two runs on two hits and two walks over 5.2 innings as the Royals were downed 6-2 by the Red Sox.

Making his first appearance for Kansas City after being acquired from San Diego as part of the Freddy Fermin trade, Bergert battled Boston ace Garrett Crochet to a 1-1 tie through five frames before the home squad finally pulled ahead for good in the sixth. Bergert tossed 61 of 85 pitches for strikes, falling just short of his first career quality start, and the 25-year-old rookie staked a claim to potentially handle at least one more turn through the rotation while Michael Lorenzen (oblique) completes a rehab assignment. If Bergert does get another start with the Royals, it would likely come at home early next week against the Nationals.
