Coach Doug WilliamsDoug Williams - Head Coach, 22nd Year

Doug Williams, whose Bulldogs have averaged 32 wins per season since 1995, enters his twenty-second season as head coach. In 2015, Williams guided the Bulldogs to a 30-13 record, a 20th trip to the Northern California State Playoffs. Under Coach Williams the Bulldogs have won 12 Coast Conference Championships in the past 21 years, most recently guiding the Bulldogs to the Coast Conference Golden Gate Championship in 2015. One of his most memorable experiences was when his first team at CSM claimed the 1995 Coast Conference National Division Championship. The Bulldogs posted a 38-11 record in Williams' first season, setting a school single-season record for victories. His twenty-one year record at CSM is 649-274 and he is a eight-time recipient of the Coast Conference Coach of the Year Award, most recently winning the award in 2015. During his tenure, 248 out of 255 players have transferred to four-year schools or signed professionally, an outstanding rate of 97%!!

Williams played NCAA Division I baseball at UC Santa Barbara during the 1987-88 seasons.  A native of nearby Belmont, Williams played the infield and pitched for Carlmont High School, from which he graduated in 1983. He began his Bulldog career as a player for the legendary John Noce during the 1984-86 seasons, including a redshirt year. In his last season at CSM, the Bulldogs won the championship of the former Golden Gate Conference, which was the school's last title until Williams guided the Bulldogs to the 1995 crown.

Williams began his coaching career in 1990 at CSM as an assistant to Coach Noce, a position he held during the last three seasons of Noce's 31-year tenure at the College. Williams also gained summer coaching experience in in a professional league in Perugia, Italy.

In 1993 Williams' alma mater, Carlmont High School, sent out an emergency call for a varsity baseball coach to lead its defending section champion and Williams answered the call. He not only coached Carlmont to its second consecutive Central Coast Section Division II Championship, but he called the pitches as his staff hurled four consecutive shutouts during the playoffs- a feat never before or since accomplished since the tournament began in 1967.

Williams was hired as assistant coach and pitching coach at the University of San Francisco in 1994. He helped that team achieve its best season in many years. When the CSM job opened in the summer of 1994, Williams returned to the Bulldogs.

Williams holds a master's degree from St. Mary's College, having written a thesis entitled "A Three-Dimensional Biomechanical Analysis of Fastball and Fork-ball pitchers." He was featured on the front page of an issue of Collegiate Baseball Magazine as a result of his ground-breaking thesis, which included a video and computer analysis of former Oakland A's pitching star Dave Stewart.

Williams, his wife, Liliana, and son Lucca, reside in Belmont.
