Garrido compiled a collegiate record of 1,975–951–9 and retired in 2016 as the coach with, at the time, the most wins in college baseball history.

[2][5] During his graduate studies, Garrido coached baseball at Sierra High School in Tollhouse, California in 1967 and 1968.

In 21 seasons with Cal State Fullerton, Garrido accumulated a 929–391–6 record with seven College World Series including three championships (1979, 1984, and 1995) and a runner-up finish in 1992.

[6] Garrido led Texas to the College World Series four straight years from 2002 to 2005 winning the tournament in 2002 and 2005 and finishing runner-up to his former team, Cal State Fullerton, in 2004.

3 in the nation at the end of the regular season, Texas was defeated at home in an NCAA regional by Stanford.

On April 29, 2011, Garrido became the first NCAA Division I coach to reach 1,800 victories as the seventh-ranked Longhorns defeated No.

[13] On May 30, 2016, the University of Texas announced that Garrido had resigned and accepted a position as a special assistant to the athletic director, Mike Perrin.

He earned more wins than any other coach in NCAA baseball history, across all levels, prior to being surpassed by Florida State University's Mike Martin in 2018.

American storyteller and adventurer Woodrow Landfair was a player of Garrido's at the University of Texas from 2003 to 2005, serving as the team's bullpen catcher and winning back-to-back Teammate of the Year awards in 2004 and 2005.

In a 2007 article in the Austin American-Statesman, Landfair was quoted praising Garrido as both a baseball and a life coach.

[18] Police reported that Garrido was driving a Porsche Cayenne west on 6th Street at about 1:00 a.m., when a DWI enforcement officer pulled the coach over since he did not have his headlights on.

After taking a sobriety test, Garrido admitted to the officer that he consumed five glasses of wine and was intoxicated.
