College of Marin freshman diver Ben Lentz won a pair of state championships this past weekend — 50 years since the last time the Mariners had a state champion in diving.

Lentz, a 19-year-old from Pleasanton, won gold in both the 1-meter and 3-meter springboard events at the 3C2A Championships. Lentz, who is coached by Steve Carrera and Denis Bondarenko, scored a 262.85 to win the 3-meter event then did even better in the 1-meter event, putting up a 310.65 score.

Lentz’s 1-meter score was just seven points shy of the 3C2A record. COM hadn’t won a state championship in diving since 1975, when David Cotton was victorious in both events.

Archie Williams standout Jackson Richardson has accepted an offer to continue his playing career at UC Davis next season.

Richardson, who played for an MLS Next team, decided to play for the Peregrine Falcons as a senior this past season. Richardson was a key part of Archie Williams’ attacking front four, helping the Peregrine Falcons to an MCAL regular-season title, a North Coast Section title, and the program’s first NorCal championship.

The Aggies featured three Marin-based players on their roster last season with Jason Hsu (Terra Linda), Ensio Sardans (Redwood), and Zack Lillington (Archie Williams). UC Davis won the Big West Championship last season and made it to the first round of the NCAA Tournament.
