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.

The Rockies optioned Molina to Triple-A Albuquerque on Thursday.

Molina made just one appearance during his brief stint with the big club, tossing a perfect inning. The Rockies will announce a corresponding move prior to Friday's game in Arizona.

The Diamondbacks plan to call up Montes De Oca from Triple-A Reno on Friday, MLB reporter Mike Rodriguez reports.

The Diamondbacks optioned Joe Mantiply to Reno on Thursday, and Montes De Oca looks as though he'll replace him in the bullpen ahead of Friday's game against the Rockies. The 25-year-old right-hander has shown improved control at Reno this season, walking just four in 19 innings while turning in a 2.37 ERA and 1.00 WHIP in 12 appearances so far. While he hasn't displayed a great strikeout punch at the upper levels of the minors, he has the potential to stick around in the Arizona bullpen.

Sauer allowed two runs on two hits and two walks while striking out two over four innings in a no-decision versus the Athletics on Thursday.

Sauer was fine in his first big-league start, but he didn't pitch long enough to qualify for the win in a 19-2 blowout. He gave up a run in each of the first two innings before settling in. Over 15.2 innings this season, Sauer has a 2.30 ERA, 0.89 WHIP and 10:3 K:BB. He's got some starting experience in the minors, but he's been utilized as a middle reliever for the bulk of his time in the majors. Clayton Kershaw (toe) is poised to make his season debut this weekend, with Landon Knack a likelier bet to stick in the rotation than Sauer.

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.

Herget was designated for assignment by the Mets on Thursday, Manny Gomez of NJ.com reports.

Herget has spent nearly the entire 2025 season with Triple-A Syracuse, so the move won't affect where he is pitching, assuming he passes through waivers unclaimed. Jose Castillo was added to the roster in the corresponding move.

Iglesias picked up the save Thursday against Washington, allowing one hit with no strikeouts over a scoreless ninth inning.

It was a much-needed clean outing for Iglesias, who had surrendered a run in each of his last three appearances and had blown two of his previous four save chances. The 35-year-old has been uncharacteristically bad in 2025, posting a 5.71 ERA in 17.1 innings after notching a sub-3.00 ERA in his last five seasons, including a 1.95 ERA across 69.1 regular-season innings in 2024.

Castillo was traded from the Diamondbacks to the Mets in exchange for cash Thursday, Manny Gomez of NJ.com reports.

Castillo was cast off Arizona's 40-man roster Monday but found a new home quickly. He has only 46.2 innings in the majors since debuting in 2018, so he'll likely fill a depth role in his new organization.
