The Athletics recalled Ferguson from Triple-A Las Vegas on Wednesday.

Ferguson was one of the club's better relievers last season, but he was sent down in June following a rough stretch in which he yielded 10 runs over four appearances. The 31-year-old seemed to get back on track at Las Vegas, permitting just one earned run with an 11:3 K:BB over 10 innings. Ferguson could pitch his way back into leveraged situations in an unsettled bullpen, though that probably won't happen right away.

The Athletics optioned Nunez to Triple-A Las Vegas on Wednesday.

Acquired from the Padres in the Mason Miller trade, Nunez was roughed up for five runs on six hits and four walks over 2.1 innings in his first two appearances with the Athletics. He will be replaced on the 26-man active roster by right-hander Tyler Ferguson, who was recalled from Las Vegas.

Hader walked one and struck out two across a scoreless ninth inning Tuesday against the Marlins.

Hader hadn't appeared in a game since Friday, so he made an appearance despite Houston holding a four-run lead. He walked the second batter he faced but ran into little trouble and has now turned in seven consecutive scoreless appearances since the All-Star break.

Smith worked a perfect ninth inning Tuesday to record his fourth save of the season in a 3-2 win over the Mets. He didn't walk or strike out a batter.

The right-hander fired 14 of 17 pitches for strikes and leaned on his defense to get the job done. This was Smith's first save since Emmanuel Clase was placed on non-disciplinary leave, with his other three coming back in late April, but he remains the favorite to handle closing duties for Cleveland for the rest of the season with Clase's future uncertain. Over his last 12 appearances, Smith has posted a 1.98 ERA, 0.95 WHIP and 13:5 K:BB over 13.2 innings.

Topa struck out one batter in a perfect ninth inning to earn a save against Detroit on Tuesday.

Topa threw 12 of his 15 pitches for strikes and quickly retired the Tigers' 8-9-1 batters to preserve the 6-3 win. He joined Erasmo Ramirez as the two bullpen arms to record saves for the Twins since the team traded Jhoan Duran at the deadline. Topa owns a 3.86 ERA and a 41:12 K:BB through 46.2 saves this season. It was his first save with Minnesota, and he entered Tuesday's contest with three in his career, all of which came during his final season with Seattle in 2023. Cole Sands allowed two runs in the eighth inning Tuesday, and it appears the Twins are still working out how the bullpen arms will be utilized moving forward.

Maton picked up the save Tuesday against the Yankees, allowing one hit and no walks in a scoreless ninth inning. He struck out one.

Maton notched his third save of the season and his first since joining the Rangers. The veteran right-hander's usage signals that he's already part of Texas' high-leverage mix, but it remains to be seen how many more save opportunities he'll see the rest of the way. Through 41.1 frames, Maton has a 2.18 ERA, 1.09 WHIP and 51:16 K:BB. It's also worth noting closer Robert Garcia had been dealing with a back issue recently, so it's possible the Rangers are easing him back into action.

Heasley signed a minor-league contract with the Royals on Tuesday.

Heasley has been a free agent since the White Sox released him at the end of March and hasn't pitched in a game at any level this season. The 28-year-old righty owns a 5.89 ERA and a 1.47 WHIP through 139 career innings in the majors and will likely serve as organizational depth while pitching for Triple-A Omaha.

Montero allowed two runs on two hits and a walk across an inning of relief in Tuesday's 6-3 loss to the Twins.

Montero, who was traded to Detroit from Atlanta before last Thursday's deadline, was making his first appearance in exactly a week. Perhaps as a result of some rust, the veteran righty wasn't particularly sharp in his team debut, and his season ERA climbed to 5.72. Montero can miss some bats, as he has 39 strikeouts in 39.1 innings this year, though he's too volatile at this point to see high-leverage work with the Tigers, which minimizes his fantasy appeal.

The White Sox recalled Hudson from Triple-A Charlotte on Tuesday.

Hudson was claimed off waivers from the Brewers on Sunday and will join the big-league roster before making an appearance with Charlotte. The big lefty was a standout in the Milwaukee bullpen in 2024, but he has a 4.35 ERA and 13:12 K:BB over 10.1 innings in the majors and a 6.84 ERA at the Triple-A level in 2025.

The White Sox Sox" data-type="SPORTS_OBJECT_TEAM" data-league-abbreviation="MLB" data-team-abbreviation="CHW">White Sox optioned White to Triple-A Charlotte on Tuesday.

He's clearing out to make room for Bryan Hudson, who will join the active roster after being claimed off waivers Sunday. White had been recalled over the weekend but did not make an appearance.
