In 2024, Marymount baseball set a program record with 10 All-Conference performers as Cassidy and his staff received the Atlantic East Coaching Staff of the Year award. The Saints were ranked for the first time in program history, reaching as high as No. 22 in the national polls. Marymount won a program-record 31 games to earn the No. 1 seed in the Atlantic East Tournament before being eliminated by Cabrini. Five Saints were named to an All-Region team by the ABCA or D3baseball.com with two more Saints being named All-State by VaSID. 

Marymount finished with a 22-19 mark in 2023 and earned six All-Conference selections. In his first season at the helm of the Marymount baseball program in 2022, Cassidy helped the team make history with a then-program record 29 wins. The Saints made a run for their second-straight Atlantic East title, but fell short in a tough battle with Immaculata in the championship round. He coached a consenus All-Region player in Alex Lemery and three All-Conference selections. 

In his final year as an assistant, Cassidy helped lead the Saints to their first-ever Atlantic East Conference title and trip to the NCAA Division III Championships in 2021. He oversaw the growth of infielder Alex Lemery and Ryan Bergenhagen, who earned Co-Player of the Year and Pitcher of the Year honors from the Atlantic East, respectively.
