Since joining the Dolphins as a sophomore, Ruth has been a staple at the top of CSI's pitching staff. She led the team with a 3.77 ERA across 122.2 innings pitched while recording 58 strikeouts. In 2025, Ruth elevated her performance, posting a career-best 3.41 ERA over 86.1 innings with a 7-8 record and 70 strikeouts. She ranked among the top five pitchers in the ECC in ERA, lowest opposing batting average (.260), and fewest runs allowed (53). Additionally, she finished the season ranked in the top 10 in the conference in strikeouts, batters struck out looking, and wins.

At the conclusion of last season, the Dolphins fell just one win shy of their first-ever ECC postseason appearance after a doubleheader split with D'Youville. Ruth earned the start in game one and delivered a complete-game performance, allowing just one run while striking out five in a 2-1 victory. Game two featured a high-scoring battle, as CSI erupted for five runs in the bottom of the second inning to take a 5-3 lead. The Saints responded with two runs in the fourth, and after the Dolphins regained a two-run advantage with a three-run inning to go up 8-6, D'Youville answered with four runs in the seventh while holding CSI scoreless to deny the Dolphins a postseason berth.

In the 2026 ECC Coaches Poll, the Dolphins were picked seventh, earning seven points.
