Gore began the day one shot back of Grob, but everything changed on the third hole Sunday. Grob made a bogey 5, while Gore carded a birdie 3. That gave Gore the solo-lead at 11-under-par; a lead he would never relinquish.
Gore's birdie at the 3rd was the first of three in a row. He added a fourth birdie of the day at the 8th to move to 14-under, four shots clear of Grob. After making the turn in 4-under-par 31, Gore parred all nine holes on the inward half for a bogey-free round of 66.
Gore, who won the 1997 California State Amateur Championship and the California State Open, was a member of the '97 NCAA Championship team, Pepperdine University.
Gore collects $76,500 for his maiden triumph, and moves from 76th to 28th on the 2000 money list.
Next week's Inland Empire Classic is the final event before the season-ending Tour Championship, which includes only the top-50 on the money list. The top 15 in earnings after the Tour Championship will secure their 2001 PGA Tour cards.
