Eduardo Salazar RP | MIN
Eduardo Salazar: Cut loose by Minnesota
The Twins released Salazar on Thursday.
Salazar made 30 appearances out of the Washington bullpen in 2025 but has spent the entire 2026 season in the minors after signing a minor-league deal with the Twins in February. He pitched effectively for Triple-A St. Paul with a 2.05 ERA, 1.14 WHIP and 18:10 K:BB in 22 innings, so Salazar shouldn't have much difficulty securing another minor-league contract.

Kodai Senga RP | NYM
Mets' Kodai Senga: Locks down third save
Senga secured the save against the Nationals on Sunday, striking out two in a clean ninth inning.
Senga continues to experience a seamless transition into New York's closer role while Devin Williams (shoulder) is on the injured list. The right-hander has now successfully converted each of his first three save chances, and he's also submitted five consecutive scoreless outings as a reliever. Given Senga's 9.66 ERA and 1.80 WHIP over 31.2 innings as a starter, it's hard to envision the Mets moving the hurler back into the rotation again this year even after Williams returns.

Kyle Hurt RP | LAD
Dodgers' Kyle Hurt: Elevated to active roster
The Dodgers recalled Hurt from Triple-A Oklahoma on Sunday.
Hurt was demoted to Triple-A on Monday, but he'll be eligible to return less than a week later after the Dodgers placed left-hander Justin Wrobleski (forearm) on the 15-day injured list in a corresponding move. The Dodgers will plug Hurt back into their bullpen, where he's produced a 4.46 ERA, 1.38 WHIP and 46:21 K:BB across 38.1 innings on the season.

Miguel Ullola RP | HOU
Astros' Miguel Ullola: Back with Houston
The Astros recalled Ullola from Triple-A Sugar Land on Sunday.
Ullola will be up with the Astros for the third time this season after giving up three earned runs on four hits and one walk while striking out seven batters across five innings over three relief appearances between his first two stints in the big leagues. He'll join the Houston bullpen as a replacement for Ronel Blanco, who was optioned to Triple-A.

Beck Way RP | KC
Royals' Beck Way: Nearing rehab assignment
Way (back) is expected to start a rehab assignment with Double-A Northwest Arkansas next week, per MLB.com.
After landing on the injured list July 28 due to low-back spasms and tightness, Way has worked through a throwing progression with no issues and is closing in on a rehab assignment. The 27-year-old has made 19 appearances with the Royals this season, posting a 3.86 ERA, 1.59 WHIP and 21:10 K:BB across 23.1 innings.

Nick Mears RP | KC
Royals' Nick Mears: Progressing in rehab
Mears (shoulder) is scheduled to throw another bullpen early this week as he continues his mound progression, MLB.com reports.
Mears has been shelved since May 29 due to a right shoulder impingement and has dealt with multiple setbacks, but the 29-year-old could finally be nearing a rehab assignment. Before hitting the injured list, the right-hander posted a 5.12 ERA, 1.50 WHIP and 15:11 K:BB across 19.1 innings.

Joe Rock RP | ATH
Athletics' Joe Rock: Claimed by A's, sent to Vegas
The Athletics claimed Rock off waivers from the White Sox on Sunday and optioned him to Triple-A Las Vegas.
Rock will join his third organization this season after spending time with both the Rays and the White Sox in 2026. All four of Rock's appearances in the big leagues came with the White Sox, with theleft-hander compiling a 3.48 ERA, 2.13 WHIP and 12:11 K:BB over 10.1 innings. The Athletics transferred Justin Sterner (knee) from the 15-day injured list to the 60-day IL to clear room on the 40-man roster for Rock.

Justin Sterner RP | ATH
Athletics' Justin Sterner: Shifts to 60-day IL
The Athletics transferred Sterner (knee) from the 15-day injured list to the 60-day IL on Sunday.
After undergoing right knee surgery Friday, Sterner had already been ruled out for the rest of the season. His move to the 60-day injured list is merely procedural, as it opens up a spot on the 40-man roster for waiver pickup Joe Rock. The 29-year-old Sterner logged a 6.12 ERA, 1.38 WHIP and 40:13 K:BB over 42.2 innings out of the bullpen before hitting the shelf July 18.

Carlos Estevez RP | KC
Royals' Carlos Estevez: Slated to throw bullpen Sunday
Estevez (shoulder) is scheduled to throw a bullpen Sunday before being re-evaluated, per MLB.com.
Estevez has been on the injured list since April 1, initially due to a left foot contusion before he suffered a right rotator cuff strain during a rehab outing May 6. The veteran right-hander began a mound progression Aug. 7 and has yet to experience any hiccups. The Royals have struggled mightily to fill the closer role in Estevez's absence this season, with Steven Cruz currently serving as the top option in the ninth inning.

Javier Assad RP | CHC
Cubs' Javier Assad: Dispatched to Triple-A
The Cubs optioned Assad to Triple-A Iowa on Sunday, Jesse Rogers of ESPN.com reports.
Assad lost his spot in the rotation in the aftermath of the Aug. 3 trade deadline and shifted to the bullpen, and he'll now end up losing his spot on the roster entirely after the Cubs reinstated Edward Cabrera (hamstring) from the 15-day injured list Sunday. Assad is expected to get stretched back out at Triple-A to offer insurance in case injuries test the big club's starting depth down the stretch.
