The Rockies recalled Justice from Triple-A Albuquerque ahead of Sunday's 6-1 loss to the Orioles. He faced two batters in relief, striking out one and walking the other.

Justice's brief relief appearance was his first in the big leagues in 2024, as he had been added to the 40-man roster last August but hadn't received a call-up from Triple-A this season after being optioned to the minors coming out of spring training. The lefty reliever submitted a 9.90 ERA, 2.50 WHIP and 21:29 K:BB in 20 innings at Albuquerque this season, but he had given up just one earned run in his last seven outings prior to getting called up.

Diaz earned the save in Sunday's 2-0 win over the White Sox, striking out the side in a perfect ninth inning.

Diaz picked up his second save in his last three appearances. In those outings, he's racked up seven strikeouts while not allowing a run. Diaz also has at least one strikeout in 18 of his last 19 appearances. For the year, he's compiled 16 saves to compliment a 3.98 ERA, 1.03 WHIP and 61:15 K:BB in 40.2 innings.

The Nationals optioned Ribalta to Triple-A Rochester on Sunday.

Four days after being recalled from Triple-A, Ribalta will now head back to the minors after giving up two earned runs on four hits and a walk over one-third of an inning during Sunday's loss to the Cubs. While the 26-year-old has yet to find his footing in the big leagues, he's been effective at Rochester with a 3.64 ERA and 1.27 WHIP across 29.2 frames.

The Giants reinstated Beck (arm) from the 60-day injured list Sunday.

Beck will join the big club for the first time all season after completing his recovery from surgery to address an upper right arm aneurysm, which cropped up during spring training. The right-hander got stretched out to 56 pitches and three innings over his five minor-league rehab outings, so he be an option for the rotation if the Giants elect to expand to six men at some point in September. For the time being, however, Beck will likely serve as a multi-inning reliever.

The Marlins recalled McCaughan from Triple-A Jacksonville on Sunday. He'll start in the Marlins' series finale in San Francisco against the Giants.

McCaughan will take over the rotation spot that previously belonged to Roddery Munoz, who was optioned to Jacksonville on Wednesday. The 28-year-old right-hander has previously made five appearances at the big-league level this season between Cleveland and Miami, logging an 8.62 ERA and 2.11 WHIP over 15.2 innings. He performed much better over his 11 starts with Jacksonville (4.53 ERA, 1.26 WHIP and 59:18 K:BB in 53.2 innings), but McCaughan doesn't make for a reliable streaming option in the majority of fantasy leagues.

The Padres recalled Cosgrove from Triple-A El Paso on Sunday.

Cosgrove will likely operate as a low-leverage reliever for the Padres as he returns to the big leagues for the third time this season. Over his previous two stints with the big club, Cosgrove gave up 19 earned runs on 23 hits and six walks over 14.2 innings.

The Padres transferred Kolek (forearm) from the 15-day injured list to the 60-day IL on Sunday.

The right-hander landed on the shelf in late July due to forearm tendinitis, and he now won't be eligible to be reinstated until after the regular season. Kolek recently resumed playing catch but has yet to throw off a mound, so he still has significant work to do in his rehab program.

The Padres reinstated Peralta (thigh) from the 15-day injured list Sunday.

The left-hander has been sidelined since mid-July due to a left adductor strain, but he's ready to rejoin the Friars after three scoreless rehab appearances. Peralta has 11 holds this season but has struggled at times with a 4.50 ERA, 1.29 WHIP and 20:12 K:BB over 34 innings.

The Padres designated Bachar for assignment Sunday.

The right-hander was optioned to Triple-A El Paso on Monday and has now lost his place on the 40-man roster. Bachar received his first big-league call-up in August but has yet to make his MLB debut.

The Pirates reinstated Borucki (wrist) from the 60-day injured list Sunday.

Borucki is active for the big club for the first time since early April. He was initially placed on the IL with triceps inflammation before he was later diagnosed with carpal tunnel syndrome in his wrist. He began a rehab assignment in late June, only to be pulled off of it shortly before the 30-day window ended when he experienced a setback. Borucki resumed the minor-league assignment Aug. 17 and looked sharp during his latest stint at Triple-A Indianapolis, covering five innings and allowing one earned run on one hit and two walks while striking out eight. Given his long layoff, Borucki is likely to be eased back into the Pittsburgh bullpen in lower-leverage situations initially.
