Rusty Filter, the longtime associate head coach at Stanford under the legendary Mark Marquess, is in his fourth season as Santa Clara's head baseball coach.

In the abbreviated 2020 campaign due to the COVID-19 pandemic, Filter led the Broncos to a 12-5 record including wins against nationally-ranked Stanford and Georgia.  Throughout the 2019-20 school year, the cumulative team GPA saw improvements and finished with a 3.289 GPA to continue the upward trend since taking over the program where his first team had a 2.894 cumulative team GPA in the fall of 2017.  Eleven student-athletes from the 2020 team were named West Coast Conference All-Academic, the highest total for the program since at least 2005.  

In 2018, Filter's first Broncos squad saw improvements across the board in pitching, hitting and defense while doubling their win total from the previous season (13 to 26) and nearly tripling the average home attendance (from 181 to 531).  The team ERA dropped by over 1.50 to 4.86, while the fielding percentage improved from .958 to .968 and scored 39 more runs.   

Filter, who was hired in June 2017, spent the previous eight years at Stanford where he was among the top pitching coaches in the nation.

He helped the Cardinal reach the NCAA Tournament five times, including three trips to the Super Regional, and developed 20 pitchers who were selected in the MLB Draft, including seven this year, for Marquess who retired this month as the fourth-winningest coach in NCAA Division I history.

Filter, a standout pitcher for San Diego State, has the distinction of mentoring two top overall picks in the MLB Draft.

While serving as the pitching coach for his alma mater, Stephen Strasburg was chosen first overall by the Washington Nationals in the 2009 MLB Draft. Four years later, Stanford's Mark Appel was taken No. 1 overall by the Houston Astros. Appel, a 2013 first-team All-American, finished his career atop the program's charts in career wins, strikeouts and innings pitched.

Filter also coached two other top 20 picks. Chris Reed (San Diego State) was selected No. 16 overall in 2011 by Los Angeles Dodgers and Cal Quantrill (Stanford) was picked eighth by San Diego Padres.

Before heading to Stanford for the 2010 season, Filter spent 21 years at San Diego State, the final 16 on the coaching staff. During his time as an assistant, the Aztecs had 58 pitchers drafted and signed to professional contracts under head coaches Jim Dietz and Hall of Famer Tony Gwynn.

Under Filter's guidance, San Diego State led the Mountain West Conference in ERA in six of the league's first 10 seasons, and ranking in the top three each of those years.

Filter began his SDSU playing career (1987-90) as a catcher, but thrived on the mound. As a senior in 1990, the four-year letterman helped lead the team to the NCAAs by appearing in 37 games (tied for second on SDSU single-season list) and notching a career-best six saves. Toronto selected him in the 1990 MLB Draft, but he embarked on his coaching career the following season as assistant and junior varsity coach for the Aztecs.

In 1993 and 1994, Filter served as the pitching coach for the Fairbanks Goldpanners of the Alaska Summer League.

Filter also coached at Mission Bay High School (Calif.) from 1992-93, claiming the CIF title in 1992.

Filter graduated from San Diego State in 1990 with a bachelor's degree in physical education.

Filter and his wife, Gina, are the parents of daughters, Reilly Nicole and Emily Claire, and son, Russell Dean II.
