The Pirates designated Darnell (hip) for assignment Thursday.

Thursday marks the second time in six days that Darnell has been DFA'd, as he joined the Pirates via waiver claim from Colorado last Friday. The 28-year-old righty posted a 3.19 ERA and 1.15 WHIP across 53.2 Triple-A innings during 2025 despite playing in the hitter-friendly Pacific Coast League, giving him a fair amount of appeal for bullpen-needy teams browsing the waiver wire.

The Pirates designated Darrell-Hicks for assignment Thursday, Alex Stumpf of MLB.com reports.

Darrell-Hicks struggled to find his footing on the mound in 2025, posting a 7.45 ERA and 1.45 WHIP through 9.2 MLB innings, as well as an 8.45 ERA and 1.93 WHIP through 38.1 innings in Triple-A. He'll lose his place on Pittsburgh's 40-man roster as a consequence of his struggles, and he'll likely have to turn things around dramatically before the club considers adding him back.

The Reds claimed Munoz off waivers from the Cardinals on Thursday.

Munoz gave up 10 earned runs in 11 innings with the Cardinals in 2025 but finished the minor-league season with a 3.28 ERA and 1.33 WHIP through 57.2 frames at Memphis. The Reds, evidently intrigued by his Triple-A statline, will now bring the 25-year-old in to add depth to their pitching staff, but because he has no more options remaining, Munoz will need to make the Opening Day roster in order to stay on the 40-man roster.

The Mets claimed Castillo off waivers from the Orioles on Thursday.

Castillo had stints with Arizona, Baltimore, Seattle and the Mets in 2025. He'll return to New York after being exposed to waivers. Castillo posted a 3.94 ERA across 32 innings of relief in the big leagues this year.

The Dodgers added Ortiz to the 40-man roster on Thursday

Ortiz jumped up from High-A to Triple-A this season, and the young southpaw, who turns 26 in January, is now a part of the 40-man roster. He logged a 2.76 ERA and a 1.24 WHIP in 16.1 innings at Triple-A Oklahoma City in 2025.

Benschoter cleared waivers Thursday and was sent outright to Triple-A Louisville.

Benschoter joined the Reds' active roster twice in 2025 but has yet to make his debut in the major leagues. He appeared in 38 games at Louisville, however, turning in a 4.12 ERA and 1.33 WHIP with a 68:22 K:BB over 78.2 innings. He's likely to report back to Triple-A to begin the 2026 campaign.

The Giants designated Black for assignment Thursday.

Black spent the majority of the 2025 campaign at Triple-A Sacramento, where he struggled to the tune of a 5.81 ERA and 1.48 WHIP alongside a 114:62 K:BB over 119.1 innings. His poor performance will now cause him to lose his place on San Francisco's 40-man roster in favor of Reiver Sanmartin, who was claimed off waivers from the Reds in a corresponding move.

The Giants claimed Sanmartin off waivers from the Reds on Thursday, Alex Pavlovic of NBC Sports Bay Area reports.

Sanmartin will get a fresh start out west after spending the last six seasons as part of the Reds organization. The left-hander, who turns 30 in April, appeared in one big-league game during the 2025 campaign. He tallied a 2.67 ERA, a 1.24 WHIP and a 55:18 K:BB across 67.1 innings for Triple-A Louisville.

Roa cleared waivers Thursday and was sent outright to Triple-A Jacksonville.

Roa pitched three scoreless innings for the Marlins this season but spent most of his time in Triple-A, where he posted a 2.83 ERA and 1.10 WHIP over 60.1 frames. Despite his strong performance, he'll now lose his place on Miami's 40-man roster and aim to earn it back during spring training.

The Marlins claimed Brzykcy off waivers Thursday from the Nationals.

Brzykcy appeared in 26 games with the Nationals in 2025, posting a 9.00 ERA and a 24:12 K:BB across 23 innings. He closed out the season at Triple-A Rochester and logged a 17.18 ERA across 11 innings after being optioned there Aug. 5.
