Zach McCambley

4:47PM: The Phillies also re-assigned right-hander Lou Trivino to Triple-A.  Like Mayza, Trivino is an Article XX(B) player with an opt-out in his minors contract this weekend.  It isn’t yet clear if Trivino will trigger his clause and enter free agency, or if he’ll bide his time at Triple-A until his next opt-out date on May 1.

9:21AM: The Phillies announced this morning that left-hander Tim Mayza was re-signed to a major league contract after the lefty exercised his opt-out clause in his minor league deal and was granted his release by the organization yesterday. To make room for Mayza on the 40-man roster, right-handed Rule 5 selection Zach McCambley was returned to the Marlins. McCambley was evidently place on (and successfully cleared) waivers at some point prior to the move to return him to Miami.

Mayza, 34, is entering his ninth major league season. He’s spent the majority of his career to this point as a member of the Blue Jays, and after an uneven start to his career when he made his major league debut in 2017 through the end of the 2019 season, he emerged from a 2020 campaign lost to injury to become one of Toronto’s more steady relief arms. From 2021 through 2023, Mayza turned in high quality results for the Jays with a 2.67 ERA and a 3.20 FIP in 155 innings of work. Of course, it should be noted that those strong numbers came with a major platoon split. While his ERA against southpaws was just 0.67, his numbers against right-handers were far more pedestrian: he sported a 4.19 ERA, a 3.96 FIP, and a 24.7% strikeout rate across those three seasons.

Even factoring in those lesser numbers against righties, however, Mayza’s fall from grace in 2024 was a shocking one. Across 50 appearances, the lefty’s ERA ballooned all the way up to 6.33, and while his 4.50 FIP suggests some of that was due to poor fortune on batted balls and sequencing he still struck out a paltry 14.4%. Ugly as those season long numbers are, however, Mayza did show some signs of returning to form after he was shipped to the Yankees midway through the season; in 18 innings of work with the Bombers, Mayza turned in a 4.00 ERA with a 3.94 FIP, though his strikeout rate still sat at a well-below average 16.2%.

That left Mayza in an uncertain place headed into 2025, and while he landed a big league deal with the Pirates he spent most of the season on the injured list due to a lat strain. He pitched just 15 total innings in the majors last year between Pittsburgh and Philadelphia (who claimed him off waivers from the Pirates midseason). In that time, he posted a 3.78 ERA and 4.16 FIP that’s more or less in line with his work as a member of the Yankees. His strikeout rate did tick back up to a more respectable 20.3%, however, and that was enough to convince the Phillies to give him another shot on a minor league pact entering camp. Mayza’s 5.40 ERA in 8 1/3 spring innings isn’t exactly inspiring, but the big news from camp is that the strikeouts appear to be back. He’s punched out 27.0% of his opponents this spring, and that was enough to convince the Phillies to put him back on their roster for the 2026 season.

As for McCambley, the righty was a third-round pick by the Marlins back in 2020. Initially drafted as a starter, McCambley converted to relief during the 2022 season and climbed the rest of the minor league ladder as a reliever. He split the 2025 season between Triple-A and Double-A, and in that time posted a combined 2.90 ERA with a 33.1% strikeout rate in 62 innings of work. That was enough to catch Philadephia’s attention in the Rule 5 draft, but he walked (six) more hitters than he struck out (four) in his 7 1/3 innings of work with the Phillies during Spring Training. That lack of control was enough for the Phillies to decide to move on from McCambley, who now returns to the Marlins as a non-roster piece who could nonetheless be called upon to contribute out of the bullpen at some point this year.
