In 2024 as a rookie, he logged 151 1/3 innings across 35 appearances, including 24 starts, posting a 4.58 ERA. While he was never a big strikeout arm, he consistently limited walks and generated ground balls, traits that appeal to a club emphasizing contact management and pitching efficiency. Last season, Spence shifted into more of a hybrid role. He made 32 appearances, primarily out of the bullpen, though he did briefly return to the rotation. His 5.10 ERA, along with home run issues, led to a midseason demotion.
