The Astros selected Hernandez's contract from Triple-A Sugar Land on Wednesday, Matt Kawahara of the Houston Chronicle reports.

Hernandez was acquired via trade from the Padres on Tuesday and has now been added to the 40-man roster and 26-man active roster. The 29-year-old boasts a 1.90 ERA and 34:9 K:BB over 23.2 innings at the Triple-A level in 2024. He made two relief appearances with San Diego in 2023, allowing four frames in three frames.

The Astros optioned Mushinski to Triple-A Sugar Land on Wednesday.

Mushinski had pitched both of the previous two days, allowing a pair of runs while cover 1.2 innings. He'll make way for a fresh relief arm in Nick Hernandez, whose contract was selected Wednesday.

Long (0-1) allowed two unearned runs on one hit and one walk while striking out one over two-thirds of an inning to take the loss Tuesday versus the Guardians.

Long put two runners on base before giving way to Angel Zerpa in the seventh inning. A Bobby Witt error would allow three runs to score, including the two on Long's line that sent him to the loss. He still hasn't given up an earned run over 5.1 innings this season, and he's generally pitched well with a 5:1 K:BB in a low-leverage role since he was brought up to the majors May 20. Long has previous experience as a starter, but none of his six big-league appearances this year have exceeded one inning. He went longer than an inning in eight of his 15 outings for Triple-A Omaha prior to his call-up, so he could still be called on to provide length out of the bullpen.

Barlow pitched a perfect inning to earn a hold in Tuesday's 8-5 win over the Royals.

Barlow has given up six runs over his last seven innings, but he's also picked up seven holds over nine appearances in that span. He's been a little shaky all season, as evidenced by a middling 3.91 ERA to go with a 1.34 WHIP and 34:12 K:BB through 25.1 innings, but Barlow still leads the Guardians with 15 holds. He's maintained a setup role while adding one save and a 2-2 record, though Cade Smith and Hunter Gaddis have been more reliable parts of the bridge to closer Emmanuel Clase.

Smith (3-0) allowed one hit over 1.2 scoreless innings to earn the win over the Royals on Tuesday. He did not strike out or walk a batter.

Smith entered the game while the Guardians were down, 5-3, but they put together a rally in the seventh inning to put him in line for the win. During his 10.1-inning scoreless streak, Smith has two wins, one save, four holds and a 14:1 K:BB. That impressive stretch has helped him get into the high-leverage mix. He's been fantastic in his first big-league season with a 1.67 ERA, 0.89 WHIP and 38:7 K:BB over 27 innings, though he's unlikely to be anything more than a setup man with Emmanuel Clase entrenched as the closer.

Cabrera (2-2) took the loss Tuesday against the Orioles, getting charged with three runs on a hit and a walk over two-thirds of an inning.

Trevor Richards gave Toronto two perfect innings as the opener, but Cabrera hit Colton Cowser with a pitch to begin the third and things went downhill from there. Cabrera has been tagged for runs in three of his last six appearances, and on the season he carries a 5.48 ERA, 1.78 WHIP and 13:15 K:BB through 23 innings as he slips into a low-leverage role.

Erceg (forearm) has begun playing catch and could throw a bullpen session as early as Sunday, the Associated Press reports.

The talented setup man just went on the IL on Friday with a retroactive designation to May 26, and Erceg may possibly be tracking toward an on-time return if this latest news is any indication. Assuming the bullpen session unfolds on schedule and without setbacks, Erceg could potentially be activated Monday, the first day he'd be eligible.

Spence (4-3) took the loss Tuesday against the Mariners, allowing four runs on nine hits and a walk while striking out three over six innings.

Spence was able to toss two shutout frames before the Mariners doubled four times in the third, leading to three runs. Spence would allow an additional run in the fourth but was able to go six up and six down over the next two innings to end his outing. Spence was able to reach six innings for the first time this year, though he battled around plenty of hard contact and only punched out three batters against a Mariners team that has the highest strikeout rate in baseball against righties. The 26-year-old owns a 3.86 ERA, 1.22 WHIP and 37:13 K:BB in 44.1 innings and lines up for another start over the weekend against the Blue Jays.

The Rays optioned Sterner to Triple-A Durham on Wednesday.

During his first stint in the big leagues, Sterner made a pair of two-inning relief appearances for Tampa Bay and struck out four while giving up two runs (one earned) on five hits and one walk. The 27-year-old will cede his spot on the 26-man active roster to right-hander Zach Eflin (back), who was reinstated from the 15-day injured list ahead of his start Wednesday in Miami.

Saucedo earned the save in Tuesday's 4-3 win over the Athletics after coming in to get the final out of the game. He did walk a batter before ending things.

Saucedo was called upon to get the final out of the game after Andres Munoz was forced to depart with a lower-back injury that flared up after a collision at home plate. He was tasked with stranding a runner at second and walked JJ Bleday before handling a Brent Rooker ground ball to end the game. It was Saucedo's second save of the year, though he also has two blown saves to his name as well. The 31-year-old owns a 3.00 ERA, 1.27 WHIP and 15:7 K:BB in 15 innings.
