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.

Bowman exercised the opt-out clause in his minor-league deal with the Twins on Sunday and elected to become a free agent, Jon Heyman of the New York Post reports.

Bowman had been scheduled to pitch Sunday, but he'll instead hit the open market. The veteran right-hander shouldn't have much trouble finding a suitor after an excellent spring between his stops with the Twins and Team Israel. In addition to allowing just one unearned run over 5.1 innings in the Grapefruit League, Bowman tossed three scoreless frames over two World Baseball Classic appearances.

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.

Akin suffered an adductor injury while warming up in the bullpen during Baltimore's Grapefruit League game against the Phillies on Saturday, Jake Rill of MLB.com reports.

Manager Craig Albernaz said after the game that he doesn't know how severe Akin's injury is, but the skipper kept him out of the game as a precaution. More information on the 30-year-old's status for Opening Day should be available in the next couple days.

The Blue Jays granted Seabold his release Saturday.

Seabold tallied an impressive 13 strikeouts in just 6.2 innings this spring, but he did so while allowing five earned runs to score. Now a free agent, he'll likely have to settle for a minor-league contract after posting a 6.07 ERA and 1.42 WHIP over 69.2 Triple-A frames in 2025.

The Blue Jays optioned Estrada to Triple-A Buffalo on Saturday.

Estrada will finish the Grapefruit League with a 4.76 ERA and 1.32 WHIP through 11.1 innings. Those numbers are improvements from the 5.73 ERA and 1.45 WHIP he posted in 97.1 Triple-A frames last year, but the Blue Jays will send him back to the minors to continue developing.

The Rangers granted Brasier his release Saturday.

Brasier struggled to establish himself this spring, allowing six earned runs over 7.1 innings in the Cactus League. Because his chances of starting the season in Texas' bullpen were looking poor, he'll exercise his right to opt out of his contract and seek another opportunity on the free-agent market.
