After losing to Jeff Tarango in three sets in last year's final, Motevassel beat him 6-4, 6-3 Sunday to win the men's singles title of the USTA National 40 Hard Court Championships in La Jolla.
Tarango, a former Stanford All-American from Manhattan Beach, was seeded first and Motevassel of Sunnyvale second. Both are left-handed former touring professionals.
"After last year, I was kind of upset," Motevassel admitted in a news release. "I had the match. I was up a set, and I was up a break. I just lost a little focus. I was playing too defensive from the back and allowed him to dictate. I played too tentative last year.
"I was focused today. I had a good game plan, and it worked fine. I took the ball a little earlier. I put him on the defense more. Getting the ball more on the rise helped me a lot today."
In father-son doubles, top seeds and eight-time defending champions Brian and Brett Joelson of Beaverton, Ore., lost to fourth-seeded Peter and Tanner Smith of Los Alamitos 6-7 (9), 7-6 (5), 7-5 in the semifinals.
