Gallen, 28, has established himself as an ace-level pitcher and is coming off a second consecutive excellent season. In 2023, he made 34 starts and tallied 210 innings with a 3.47 earned run average. He struck out 26% of batters that came to the plate against him, walked just 5.6% of them and kept 41.8% of balls in play on the ground.
The righty was then a key part of the Diamondbacks making a surprise charge to the World Series. Though his ERA ticked up to 4.54 in the postseason, he logged 33 2/3 innings over six starts, a notable workload for a club without much pitching depth.
He was a third-round pick of the Cardinals but he was twice traded to end up in the desert. He was one of four players that went to the Marlins in the Marcell Ozuna trade and later was flipped to the Snakes for Jazz Chisholm Jr. He first qualified for arbitration going into 2023 and played last year on a $5.6MM salary, now getting into eight-figure territory. He will be due one more raise in 2025 before he’s slated for free agency.
