Mark DeLuca, the Berkeley High boys basketball coach who guided the Yellowjackets to their first state championship game since 1924, has resigned.

In an e-mail sent to this newspaper, DeLuca wrote that the past season was an amazing one but that “I’ve had my fill of the Berkeley thing.”

When asked in a phone interview what he meant by the “Berkeley thing,” DeLuca declined to give specifics. “Berkeley can be really, really good with the on-court stuff. The off-court stuff can be … particularly nutty.

“I’m just saying the current system, the way Berkeley operates, they go out of their way to be fair to everybody and they end up being fair to nobody,” he said. “The vast majority of parents and the vast majority of players I worked with in Berkeley were fabulous, and I will miss them … I’ve met some of the best parents I’ve every met at that school.”

DeLuca, 48, wrote in the e-mail that he chose to resign now so the school would have “time to find a quality coach because the team coming back is loaded.”

DeLuca, who said he will coach again, perhaps even next season, did make it a point to write in his e-mail that he wants to coach at a school where he can be on campus.

He is the Director of Student Life for El Sobrante Christian School.

DeLuca coached Berkeley for three seasons and led the Yellowjackets to an overall record of 67-25.

Before taking the job at Berkeley, DeLuca was at De Anza High in Richmond for two seasons and at Pinole Valley for nine seasons.

DeLuca’s team had quite a run in this year’s postseason.

In the North Coast Section Division 1 playoffs, No. 7 seed Berkeley beat No. 2 seed Dougherty Valley in the quarterfinals before losing to No. 6 seed Monte Vista in the semifinals. In the CIF Division 1 Northern regionals, No. 7 seed Berkeley upset No. 2 seed Jesuit-Carmichael, No. 3 seed Monte Vista and No. 5 seed Menlo-Atherton to win the Northern regional title. In the Division I state championship game, Berkeley fell to Crespi-Encino 68-53.

Berkeley also reached the Division 1 Northern regional semifinals in 2015, and made the NCS Division 1 playoffs in 2014.
