STATEN ISLAND, N.Y. — Tom Tierney, the decorated former Tottenville Pirates head coach who won five PSAL city titles and four Coach of the Year honors from 2000 to 2016, has joined the College of Staten Island baseball coaching staff following his retirement from the Huguenot school, the program announced.

Before taking over as Tottenville’s head coach, Tierney spent five years as an assistant under his father, Tom Sr., himself a legendary figure in Pirates history.

Tierney began his own college playing career at John Jay before transferring to CSI, where he posted an impressive .504 batting average and 1.580 OPS. He still ranks among the program’s single-season leaders in batting average, hits, RBI, home runs, and slugging — making this a true homecoming for the former Dolphins slugger.

But before leaving John Jay, Tierney had the opportunity to share the diamond with current Dolphins head coach Michael Mauro, who also went on to serve as one of Tierney’s assistants during the beginning of his tenure at Tottenville.

“Having Tom coach alongside me is both an exciting and emotional moment for me,” Mauro said.

“I learned how to coach from him throughout all those years. To have everything come full circle and have him next to me in the dugout is surreal,” he continued.

Tierney’s playing career didn’t end on Victory Boulevard, either — his standout numbers at CSI earned him a professional contract with the Atlanta Braves, where he spent two years in their minor league system.

With Tierney’s wealth of experience as both a player and coach, along with his strong bond with Mauro, the new hire will look to build on the Dolphins’ landmark 2025 campaign, highlighted by the program’s first-ever Division II playoff appearance.

CSI will take to the field again to begin its 2026 season in mid-February.
