Mayor Dunlap presented a proclamation celebrating Fullerton Union High School’s remarkable contribution to Major League Baseball history. Fullerton Union High School has produced four pitchers who have thrown no-hitters in Major League Baseball.

The first no-hitter was thrown on July 1, 1920, by Walter Johnson, pitching for the Washington Senators against the Boston Red Sox at Fenway Park. Johnson attended Fullerton High School from 1904 /05.

The second no-hitter was thrown on April 27, 1973, by Steve Busby, pitching for the Kansas City Royals against the Detroit Tigers at Tiger Stadium. Busby graduated from Fullerton Union High School as a member of the class of 1967. The third no-hitter was also thrown by Busby on June 19, 1974, pitching for the Royals against the Milwaukee Brewers.

Fun fact: The Brewers were managed, at the time, by Del Crandall, a 1947 Fullerton Union High School graduate. During his MLB playing career, Crandall was among the few catchers in baseball history to catch three no-hitters.

The 4th no-hitter was thrown on September 29, 1983, by Mike Warren, pitching for the Oakland Athletics against the Chicago White Sox at Oakland Alameda Coliseum. He graduated from Fullerton Union High School class of 1979 and became only the 3rd rookie in Major League Baseball history to throw a no-hitter.

Mike Lorenzen threw the 5th no-hitter on August 9, 2023, pitching for the Philadelphia Phillies against the Washington Nationals at Citizens Bank Park in Philadelphia. He graduated from Fullerton Union High School in 2010 before attending Cal State Fullerton and playing for the Titans.

The Fullerton City Council, on behalf of the City of Fullerton, recognized Fullerton Union High School and the Fullerton Union High School Baseball Program for their exceptional contributions to the game of baseball and for their five no-hitters in the Major Leagues.
