The Phillies optioned Shugart to Triple-A Lehigh Valley on Sunday.

Shugart was acquired from the Pirates in January but has missed out on the Opening Day roster after posting a 3.72 ERA and 7:7 K:BB over 9.2 Grapefruit League innings. The right-hander had a 3.40 ERA and 1.11 WHIP across 35 appearances with Pittsburgh last year and should be up with Philadelphia at some point this season when bullpen depth is needed.

The Phillies released Mayza on Sunday and re-signed him to a major-league contract.

The 34-year-old lefty joined Philadelphia as a non-roster invitee in January and was able to earn a roster spot after giving up five earned runs with a 10:2 K:BB over 8.1 innings during spring training. Mayza made just 15 regular-season appearances last year due to a shoulder injury but was a reliable high-leverage arm as recently as 2023, when he recorded a save and 22 holds with a 1.52 ERA for the Blue Jays over 69 outings.

The Diamondbacks informed Loaisiga on Saturday that he's secured a spot on the Opening Day roster, Jorge Castillo of ESPN.com reports.

Arizona will officially add Loaisiga to the 26-man roster shortly before Thursday's season opener in Los Angeles. The right-hander posted a 7:2 K:BB while allowing three earned runs on eight hits over seven innings during the Cactus League. While Loaisiga is likely to begin the season in middle relief, he could earn higher-leverage opportunities quickly in an unsettled bullpen.

San Diego optioned Jacob to Triple-A El Paso on Saturday.

Jacob tossed a career-high 33.1 regular-season innings with the Padres in 2025, posting a 5.13 ERA, 1.50 WHIP and 23:14 K:BB over 33.1 innings across 29 appearances. The righty reliever has a 6:2 K:BB through 3.2 frames this spring but has also given up a pair of runs. Jacob will start the campaign with El Paso, though he could be an option to fill a big-league bullpen spot at some point this year.

San Francisco signed Borucki to a one-year contract Saturday, Robert Murray of FanSided.com reports.

Borucki spent time in White Sox camp this spring but was released Friday. He looked good in Grapefruit League action, however, pitching six scoreless innings with an 8:1 K:BB over six appearances, and the Giants were quick to snap him up. Borucki gives San Francisco another lefty in the bullpen and has plenty of experience with 187 career MLB appearances under his belt.

The Reds optioned Maxwell to Triple-A Louisville on Saturday.

Maxwell struggled to limit traffic on the basepaths during spring training, posting a 5.40 ERA and 2.04 WHIP over 8.1 innings, though he managed to collect 13 strikeouts in that span. If the 25-year-old can right the ship at Louisville, the Reds may consider recalling him to join the big-league bullpen as a depth piece.

Adam (quadriceps) pitched a perfect inning with one strikeout against Colorado in a Cactus League appearance Friday.

Adam entered in the sixth inning and retired the Rockies in order on 12 pitches. It was the first time the righty reliever has appeared in a game this spring, as he's still working to get fully ramped up following the surgery he underwent early last September to repair a ruptured left quadriceps tendon. According to AJ Cassavell of MLB.com, Adam will aim to make another exhibition appearance Monday, and if that goes well, there's still a chance he could make the Padres' Opening Day roster.

Manaea will not begin the season in the Mets' starting rotation, although manager Carlos Mendoza indicated Saturday that the veteran southpaw would be used in a piggyback role, Will Sammon of The Athletic reports.

Mendoza didn't specify which starter would get an abbreviated workload to accommodate Manaea, however. Manaea's velocity has been down this spring, and getting used in a long-relief role could buy him more time to round into form. His actual Grapefruit League results have been solid as he has a 3.72 ERA and 9:2 K:BB in 9.2 innings. Freddy Peralta, David Peterson, Nolan McLean, Clay Holmes and Kodai Senga will open the season in the rotation.

The Phillies reassigned Richards to minor-league camp Saturday.

Richards inked a minor-league contract with the Phillies in December but wasn't able to crack the Opening Day roster after posting a 3.38 ERA and 1.25 WHIP across eight innings in eight Grapefruit League games. He'll likely open the season in Triple-A but would be a candidate for a major-league call-up if the Phillies need an extra arm out of the bullpen.

Manager Craig Stammen said Friday that Matsui (groin) will begin the season on the injured list, AJ Cassavell of MLB.com reports.

Matsui hasn't appeared in a game this spring after suffering a groin injury during a live BP session in February. He resumed throwing off a mound in early March, and Stammen added that the 30-year-old southpaw is slated to resume facing live hitters within the next several days. Assuming his rehab continues to progress smoothly, he may not need to spend more than the 15-day minimum on the IL.
