Kittredge (knee) tossed one scoreless inning, allowing two hits while striking out a batter in Triple-A Norfolk's loss against Nashville on Sunday, Roch Kubatko of MASNSports.com reports.

Kittredge threw all nine of his pitches for strikes in the inning, completing his second appearance out of the bullpen with Norfolk on his rehab assignment. The relief pitcher has missed the entirety of the 2025 campaign while on the 15-day injured list after he underwent arthroscopic knee surgery in early March. Kittredge appears to be on the cusp of an activation and may require just one more outing in Triple-A before potentially joining the Orioles' roster.

The Orioles optioned Selby to Triple-A Norfolk on Sunday.

Selby was recalled by Baltimore on Thursday and will return to Norfolk to make roster space for Zach Eflin (lat) to come off the injured list. Selby has made three appearances in the big leagues this season and has given up two earned runs with a 5:1 K:BB over 3.2 innings.

The Astros optioned VanWey to Triple-A Sugar Land on Sunday.

The right-hander was called up by Houston on Friday and will return to Triple-A after giving up five runs over two innings Saturday versus the Reds. VanWey is being sent down to create roster space for Shawn Dubin (shoulder), who was reinstated from the injured list.

The Astros reinstated Dubin (shoulder) from the 15-day injured list Sunday.

Houston optioned fellow righty reliever Logan VanWey to Triple-A Sugar Land to open up a spot in the bullpen for Dubin, who had been on the shelf all season due to right shoulder inflammation. After giving up just one earned run while striking out nine over five innings during his rehab assignment with Sugar Land and Double-A Corpus Christi, Dubin looks poised to handle a middle-relief role.

Gusto will start Monday's game against the Royals in Houston, Brian McTaggart of MLB.com reports.

Gusto made his latest appearance in relief May 4 against the White Sox, giving up three unearned runs while recording two outs. Prior to that outing, Gusto had made four consecutive starts and was generally impressive, going 2-1 with a 3.79 ERA, 1.26 WHIP and 20:4 K:BB in 19 innings. The Astros will reopen a starting role for Gusto as a result of Hayden Wesneski (elbow) landing on the injured list Friday.

Yarbrough is starting Sunday's game against the Athletics, Chris Kirschner of The Athletic reports.

The left-hander will make another spot start after Carlos Carrasco was DFA'd on Tuesday. Yarbrough has pitched well as a swingman with a 3.72 ERA, 1.24 WHIP and 18:9 K:BB across 19.1 innings. He set season highs with 64 pitches across four frames in his previous outing May 3 and is likely to have a similar workload Sunday in Sacramento.

The White Sox optioned Freeman to Triple-A Charlotte on Sunday.

He'll give up his spot on the 26-man roster to right-hander Yoendrys Gomez, whom the White Sox claimed off waivers Saturday from the Dodgers. Freeman made four relief appearances in his first look at big-league hitters and was charged with two earned runs on four hits and one walk over 2.1 innings.

Cantillo allowed five runs on seven hits and one walk while striking out three over 1.1 innings in Saturday's 7-1 loss to the Phillies.

Cantillo entered with a runner on base and one out in the eighth inning, turning a 1-0 deficit into a 7-0 game after the left-hander allowed the first seven batters he faced to reach base. Cantillo had been effective out of the bullpen prior to this disaster and entered Saturday with a 1.96 ERA over 18.1 innings.

Tonkin (shoulder) suffered a setback during his rehab assignment, the St. Paul Pioneer Press reports. He's made six rehab outings between Low-A Fort Myers and Triple-A St. Paul, allowing eight earned runs with a 10:4 K:BB ratio in 7.2 innings.

Details on his setback are not clear, but his timetable to return is now uncertain. Tonkin suffered a right shoulder strain early in spring training and began the season on the injured list.

Duran earned a save against the Giants on Saturday, allowing one hit and striking out one batter in a scoreless ninth inning.

Duran got the call with Minnesota clinging to a one-run lead in the ninth and got the job done on just 10 pitches. He gave up a bunt single to the first batter he faced, but the runner was quickly wiped out on a double-play groundout. Duran has enjoyed a stellar month of May so far, picking up five saves in six appearances while pitching six scoreless frames and posting a 10:2 K:BB.
