The 20-year-old Trimble, who stunned the field with a 5-under-par 67 at the end of the day yesterday (when the winds were strongest), played the Shore Course today and ended with 67-74--141 for two rounds, good for a five-shot margin over Brett Kanda of La Crescenta, who shot even-par 72 today on the Dunes Course for a two-day total of 146.

Eddie Olson of Aptos finished third at 147; Kanda and Olson were teammates of Trimble at UNLV (Trimble is transferring to the University of San Diego) this fall.

The low 32 scorers advanced to match play beginning tomorrow, with the final five spots being determined by a three-hole playoff involving 10 people. The second round of match play is Wednesday, quarterfinals and semifinals are Friday and the 36-hole championship match is Saturday. All matches will be played on the Shore Course.
