Lathrop annexed its first boys basketball championship in school history on Thursday, defeating Los Banos on the road, 63-60.

The Spartans (12-2, 15-11 overall) are guaranteed to have at least a share of the Western Athletic Conference championship. They can win it outright if Mountain House drops either of its final two contests against Pacheco and Grace Davis.

“I’m honored to be in the position I am at Lathrop High, to work with such high character and hard-working, young student-athletes and to have the support of the athletic director and principal,” Lathrop coach Charles Roth said. “These find young men deserve this, and I’m proud to be their coach.”

Izaias White led Lathrop with 20 points, and Napolean Reeves had 13. They sparked the Spartans’ strong start, helping the team build a 23-11 by scoring six points apiece in the first quarter. Seven other Lathrop players contributed to the scoring.

Los Banos (5-8, 14-11) was led by Anthony Blancarte’s 20 points. Camron Lockett contributed 15.
