Hartlieb signed a major-league contract with the Yankees and was selected to the active roster Sunday.

The right-hander elected free agency after being designated for assignment by the Yankees a few days ago, and he's quickly back on the MLB roster. Hartlieb allowed three earned runs over one inning during his lone appearance with New York and should fill a low-leverage relief role.

Dominguez (back) picked up his second save of the season in Sunday's 2-1 win over Atlanta, striking out two while allowing one earned run on two hits over one inning.

Dominguez wasn't available for either of the Orioles' previous two games due to a sore back, but interim manager Tony Mansolino was comfortable turning to the right-hander to protect a two-run lead in the ninth inning Sunday with normal closer Felix Bautista being rested following appearances on both of the past two days. The save didn't come easily for Dominguez, who gave up a one-out solo home run to Sean Murphy before Ozzie Albies singled to put the tying run on base. However, Dominguez settled in thereafter, striking out Drake Baldwin and then inducing a weak grounder from Michael Harris to close out the contest. The 30-year-old Dominguez has posted a 3.31 ERA, 1.25 WHIP and 47:20 K:BB across 35.1 innings this season while working primarily in a setup role.

The Blue Jays optioned Estrada to Triple-A Buffalo on Sunday.

Estrada was sent back to the minors to clear room on the 26-man roster for Ryan Burr (shoulder), who was reinstated from the 60-day injured list. After getting his first big-league call-up Friday, Estrada impressed in Saturday's 11-inning win over the Angels, giving up one earned run on two hits and no walks while striking out four over four frames of long relief.

The Blue Jays activated Burr (shoulder) from the 60-day injured list Sunday.

The right-hander has been on the shelf all season due to shoulder issues but is now ready for his 2025 MLB debut after a five-outing rehab assignment, during which he had a 6:3 K:BB over 5.1 scoreless frames. Burr made 34 appearances for Toronto last season and had three holds with a 4.13 ERA, 1.26 WHIP and 47:12 K:BB across 32.2 innings.

Jax threw a scoreless eighth inning with a walk in Saturday's 6-5 win over the Rays. He has a 3.86 ERA with 18 holds in 37.1 innings this season.

It was a rare appearance for Jax without a strikeout, as he has an eye-popping 61:9 K:BB and 39.1 percent strikeout rate. After early struggles (10 earned runs in his first eight innings) that saw him briefly demoted to lower-leverage work, Jax has a 1.84 ERA since April 22 and has been the primary set-up man to closer Jhoan Duran. Unlike previous seasons, manager Rocco Baldelli has mostly kept Duran in the ninth inning instead of deploying him in higher-leverage spots earlier in the game, limiting Jax's save opportunities.

Interim manager Tony Mansolino said Dominguez hasn't been available out of the bullpen for the Orioles' last two games due to a sore back, Jake Rill of MLB.com reports.

Per Brendan Mortensen of MASNSports.com, Mansolino said Dominguez reported the injury after he "slept funny," but the skipper is hoping the reliever will be available Sunday. Dominguez has been a key bridge to closer Felix Bautista this season, collecting 13 holds, one save and two wins while pitching to a 3.15 ERA over 34.1 innings.

Adams allowed five runs on nine hits and no walks while striking out one over four innings Saturday against Tampa Bay.

Adams was used as a bulk reliever in a bullpen game for the Twins. He gave up plenty of loud contact in his MLB debut as he allowed a 47.4 percent hard-hit rate, according to Baseball Savant. With Bailey Ober (hip) likely to return after the All-Star break, it's not clear if Adams will be used in a similar role again Friday when the Twins have an opening in their rotation.

The Rays optioned Rock to Triple-A Durham on Sunday.

He'll be replaced on the 26-man roster by Joe Boyle, who had been starting for Durham and could serve as a swingman during the upcoming week. Rock made his MLB debut June 28, covering two innings while allowing two earned runs on four hits and striking out four. The lefty reliever went unused in the Rays' ensuing six games.

Hurter tossed a scoreless inning of relief to record a hold in Saturday's 1-0 win over the Guardians.

After starter Casey Mize dazzled over seven scoreless innings, Hurter worked the eighth for his third hold of the year before Tommy Kahnle closed things out in the ninth. Hurter has been a bit rocky recently, allowing 12 runs (six earned) across seven innings in his last eight appearances. However, the lefty's numbers on the season are still strong, as he's sitting with a 2.72 ERA and 45 strikeouts through 43 innings out of Detroit's bullpen.

Munoz struck out two in a perfect ninth inning to earn the save Saturday against the Pirates.

The right-hander was called upon to close out a 1-0 game and did so with ease, inducing five whiffs and retiring the side in order on just 10 pitches. Munoz continues to be one of the most reliable closers in MLB and hasn't given up an earned run in his past eight outings. Overall in 2025 he's gone 20-for-25 in save chances with a 1.09 ERA, 0.85 WHIP and 44:13 K:BB across 33 innings.
