Haas likes Riviera
Defending champion Bill Haas outplayed the rest of the pack, firing an impressive seven-under 64, three shots better than the next lowest round — which is the second-largest margin of the season (Phil Mickelson was four clear of the rest when his putt for 59 lipped out in the first round in Phoenix).
Haas kicked off the day in a ho-hum style, parring the first hole, which is playing the easiest this week, at Riviera. He opened with four straight pars before he appeared to get his rhythm going with birdies on Nos. 5 and 7. But the game-changer was rolling in a tough 30-footer for birdie on No. 9, chipping-in for eagle on No. 10 and getting up-and-down (for birdie) on No. 11, and then he made some good par saves to keep the momentum going.
