STOCKTON — Jack Thomson became the 35th member of California’s 500-win club back on March 23 when his Sierra High baseball team routed Del Campo 13-3 in a nonleague contest.

With other coaches reaching career milestones this season, Mark Tennis of ESPN Rise and Cal-Hi Sports updated the state’s high school record book this past weekend.

As of games played through last Friday, Thomson is ranked 33rd along with former Selma coach Allen Crospey (1958-1990) with 502 career wins. Thomson first coached at Manteca High from 1981-1995 before taking over Sierra’s fledgling program in 1996.

John Stevenson of El Segundo (1960-2009) tops the list with a 1,059-419 record. Second with an 879-336-20 career mark is Cordova’s Guy Anderson, who leads coaches hailing from the Sac-Joaquin Section.

Jeff Stout of Yucaipa hit No. 700 earlier this season. Sam Blalock of San Diego’s Rancho Bernardo High is closing in on 800, and Fresno High’s Ken Papi is flirting with 600.

There are some familiar names from the southern half of the SJS on the list, like Escalon’s Bob Louriero (1963-2004) with 604 victories and Ceres’ Art McCrae (1960-1996) with 550.

“That’s pretty impressive company,” Thomson said after Sierra’s Valley Oak League game at Weston Ranch Monday. “I don’t know if I belong in it, but it’s some pretty impressive company.”
