Bill Barrale enters his 21st season as the head coach of the Williams College baseball team in the 2026-27 academic year with a 318-300-1 record (.515) at the helm of the program. His teams have won at least 22 games seven times — most recently in 2025 — during his tenure as head coach. 

Hired prior to the 2005 season as an assistant coach, he was promoted to head coach two years later. And in his first season, he led the Ephs to a NESCAC Championship while winning 27 games, the fourth most in a single season in program history. Williams won a pair of games in the NCAA Regional before bowing out.

During the 2025 season, the Ephs were the runner-up in the NESCAC Championship, going 22-15 overall and 7-5 in the NESCAC. Williams swept Bowdoin during a best-two-of-three NESCAC Quarterfinal series on May 3-4 in Brunswick, Maine. During a 7-5 win at Wesleyan on April 27, Barrale earned his 350th career victory, and then during an 11-3 victory over MCLA on April 29, he collected his 300th triumph at Williams.

At the conclusion of the 2024 season, Henry Juan was named to the D3baseball.com All-Region I Third Team and to the NESCAC All-Conference Second Team for the second consecutive season. During the 2022 season, Eric Pappas garnered All-NESCAC honors for the third time under Barrale's leadership. 

In 2019, Williams won the NESCAC West Division title for the first time since 2010. The 2019 Ephs went on to make it to the NESCAC Semifinals with an overall record of 24-11. Senior first baseman Doug Schaffer was named to the Google Cloud Academic All-American First Team and was also the NESCAC Player of the Year.

In his second year in 2008, Barrale guided the Ephs to a record of 24-12 and a second straight NESCAC West title. Barrale captured his third consecutive NESCAC West title in 2009 when his Ephs posted a record of 25-12 and a NESCAC West mark of 9-3.

The deciding game in the NESCAC West 2009 season came on May 3 in Pittsfield, Massachusetts, when the Ephs and Amherst squared off in a game celebrating the 150th anniversary of the oldest college game in America. Williams prevailed, 8-5, in a game seen live on ESPN360.com and later on ESPNU. 

In April 2009, Barrale's Ephs defeated the third oldest and winningest college team in America when they ventured into Bronx, New York, and defeated NCAA Division I Fordham Unviersity, 5-2.

Prior to joining the Williams baseball and football staffs, Barrale served as the head coach of baseball at Norwich University for five years (2000-04) and as an assistant football coach for six years. With the baseball program at Norwich, Barrale went 52-74 overall and 44-35 in the Great Northeast Athletic Conference (GNAC). His cumulative record as a Division III baseball coach is 370-375-1.

In the summer of 2002, Barrale served as an assistant coach of the Bourne Braves in the Cape Cod League.

Barrale is a 1994 graduate of Northeastern University and was a standout in football and baseball. In his senior year, he led the 1994 Huskies to a 35-16 record and the North Atlantic Conference (NAC) championship, plus was named NAC Tournament MVP and earned NAC All-Star honors.

Barrale received his masters’ degree in student personnel services from Rowan University in 2004.

Barrale resides in Williamstown with his wife, Alix (Williams’ field hockey head coach), and four children.
