Vaughn was named head coach of the Aggies in August 2011. Vaughn completed his third season at the helm of his alma mater and 22nd overall with the program in 2014. The former pitching coach proved he could work just as well with hitters and the Aggies boasted the third best batting average in the Big West, hitting .283 over 56 games. UC Davis also had the third best on-base percentage (.359) and the third most doubles (95) in the conference and ranked No. 4 in runs scored (297). Despite all the firepower at the plate, Vaughn also instilled a great sense of patience in his hitters, as the Aggies struck out just 271 times, the fewest in the league. After graduating seven pitchers, including all three weekend starters, following the 2012 season, Vaughn gave innings to five freshman arms in 2013. Redshirt freshman Max Cordy recorded six saves as the teams' closer while Spencer Henderson, Jordan Lazor, Dan Gallagher and Zach Williams also saw time out of the bullpen. While the Aggies didn't advance to the postseason in 2013, Vaughn's tenure on the coaching staff has included two trips to the Division II College World Series (1995 and 2003) and one to the Division I postseason (2008). In his time on the coaching staff at UC Davis, Vaughn has mentored 37 players who have gone on to sign professional contracts, including 15 pitchers.

In Vaughn's tenure as pitching coach, five of his ptichers have been selected as conference pitcher of the year. Vaughn has coached some of the best pitchers in UC Davis history. Under his guidance, two-time All-American Justin Reid posted a 1.82 ERA as a sophomore - the program's lowest in 26 years - then struck out a school record 125 batters his junior year. Reid was inducted into the Cal Aggie Athletics Hall of Fame in June of 2010. Reid joins Dave McKae, Justin Fitzgerald, and Andy Suiter as one of several Vaughn protegés whose names are scattered throughout the UC Davis record books.
