He joins the rotation projected to include left-handed players. Garrett Crochet and right handed sonny gray, brian bello And johan oviedo.
Suarez, 30, has been a steady and underrated pitcher philadelphia phillies Since 2021, he has a 3.25 ERA over the past five seasons, relying on a six-pitch repertoire that allows him to overcome below-average fastball velocity.
The left-hander’s velocity has dropped from 93.4 mph to 92.0 to 91.2 over the past three seasons, but his ERA has gone from 4.18 to 3.46 to 3.20 and his WAR has gone from 2.4 to 3.4 to 4.0.
After an All-Star season in 2024, Suárez focused more on his changeup and cutter against righties and more on his slider against lefties in 2025 (along with reducing his arm slot) as he went 12–8 with a 3.20 ERA, while setting career highs with 151 strikeouts and 157 innings pitched as he battled back problems.
