McFadden joined the Big Green coaching staff in the fall of 2018 to help with the pitchers and serve as the bullpen coach after spending two seasons at Missouri Western.

Isler led the team with 55.1 innings pitched while Albert posted the most strikeouts, 51, including his career high 11 in his start vs. the Cornell Big Red. Joseph Chambers made 16 appearances out of the bullpen, the most of the Big Green, leading the team with a 4.13 ERA.

The Big Green also snapped a losing streak against Princeton, winning their first game over the Tigers since 2022.
McFadden's pitching background shined through in his first season at the helm, as the Big Green's staff posted a league low 4.32 ERA.

Additionally, Nate Kugler's 3.35 ERA was the fourth best among Ancient Eight teams. Dartmouth took home four All-Ivy postseason honorees including their first First-Teamer since 2022.
