The Red Sox optioned Criswell to Triple-A Worcester on Friday, Chris Cotillo of MassLive.com reports.

The right-hander was called up by Boston on Wednesday and will return to Triple-A without seeing game action. Criswell appeared in three games for the Red Sox at the start of the season and gave up five earned runs over 4.1 frames, though he's been dominant in Worcester's rotation with a 1.99 ERA in five outings.

The Red Sox selected Burdi's contract from Triple-A Worcester on Friday, Chris Cotillo of MassLive.com reports.

Burdi has dominated at Worcester this season, yielding just one run with a 25:5 K:BB across 16.2 relief innings. The 32-year-old got into 12 games with the Yankees last season, collecting a 1.86 ERA and 12:9 K:BB over 9.2 frames. Burdi is likely to work in middle relief.

The White Sox selected Castro's contract from Triple-A Charlotte on Friday.

Castro was acquired from the Astros for international signing bonus pool money and has immediately been added to the big-league roster. The veteran reliever has posted a 2.29 ERA and 20:8 K:BB over 19.2 innings at the Triple-A level this season.

The White Sox optioned Shuster to Triple-A Charlotte on Friday.

Shuster has managed just a 7.59 ERA over eight appearances out of Chicago's bullpen this season. He's fared much better at Charlotte, where he's allowed only two runs with a 15:3 K:BB over 11.1 innings.

Armstrong walked one in a scoreless and hitless inning to earn the save in Thursday's 1-0 win over the Astros.

This was a game played on narrow margins, and Armstrong got the job done after Jacob deGrom outdueled Hunter Brown over the first eight innings. This was Armstrong's second save in three days, and it appears he's the next man up while Luke Jackson (hand) and Chris Martin (elbow) are unavailable. Armstrong has done fairly well this year with a 2.89 ERA, 1.13 WHIP and 20:9 K:BB across 18.2 innings, earning two saves and two holds as well as one blown save in 17 appearances. He's just a temporary closer for now, and it's likely Armstrong will resume more of a middle-relief role once the Rangers' bullpen is healthier.

Boushley was optioned to Triple-A Round Rock on Thursday.

Boushley has split the season almost exactly evenly between the majors and Round Rock. He threw 2.1 shutout innings Wednesday and has allowed only one earned run across his last 8.1 frames in the majors. Cole Winn was called up in a corresponding move.

The Astros traded Castro to the White Sox on Thursday in exchange for cash, Robert Murray of FanSided.com reports.

Castro signed a minor-league deal with Houston during the offseason and has started the Triple-A season with a 2.29 ERA and 1.20 WHIP across 19.2 innings. The 30-year-old will now join a White Sox organization searching for answers in its bullpen, and his hot start in the minors figures to give him a decent chance at joining the South Siders relatively soon.

Wilson (0-2) took the loss Thursday against Cincinnati, allowing seven runs on 10 hits and one walk with three strikeouts over 5.1 innings.

Wilson made his fifth consecutive appearance at the back end of an injury-depleted White Sox rotation, and he allowed his most hits and runs in an outing this season, including three solo home runs. Since stepping into the rotation, Wilson has posted a 6.86 ERA across 21 innings. He's tentatively scheduled for a start next week against the Mariners.

Sands recorded his first save of the season in the second game of Wednesday's doubleheader against the Orioles, pitching a perfect ninth inning in an 8-6 win. He didn't walk or strike out a batter.

Jhoan Duran and Griffin Jax both worked the opening game of the twin bill, leaving Sands to handle the save chance in the nightcap. The 27-year-old righty has been effective in a high-leverage role this season, collecting two wins and five holds over 18 appearances in addition to Wednesday's save while delivering a 2.70 ERA, 1.14 WHIP and 12:6 K:BB through 16.2 innings.

Duran recorded his eighth save of the season in the first game of Wednesday's doubleheader against the Orioles, giving up a hit and striking out one in a scoreless ninth inning.

The Twins closer continues to dominate. Duran has yet to blow a save in 2025, and he's delivered 10 straight scoreless appearances, posting a 0.90 WHIP and 14:3 K:BB over 10 innings during that stretch. After some early-season usage which suggested manager Rocco Baldelli might be viewing him as more of a high-leverage fireman, Duran has maintained firm control of ninth-inning duties for Minnesota.
