As a high school sophomore from Cypress in neighboring Orange County, Woods played his very first PGA Tour event, on a sponsor's exemption (as an amateur) at Riviera in 1992; he shot 72–75 and missed the cut by six strokes. His best finish at L.A. was in 1998, when the Nissan Open was held at the Valencia Country Club (Riviera was being prepared for the U.S. Senior Open). Woods shot 65–66 on the weekend, but lost in a playoff to Billy Mayfair, one of only two playoff losses on tour (15–2 through February 2014). Woods finished tied for second in 1999 and had top-10 finishes in 2003 and 2004. The 2005 event had only two rounds due to rain; Woods finished 13th. He played at Riviera in 2006, also rain-plagued, but withdrew after two rounds due to illness, missed the next eleven editions, then returned in 2018
