Jhonattan Vegas had seven birdies, including three in a row at one point, and just one bogey on his way to a 65 and the early lead in the opening round at CordeValle.
This marks the second straight week that Vegas has gotten off to a good start. Last week in Las Vegas, he opened with a pair of 68s before a final-round 73 and a tie for 46th.
Vegas entered this week 112th on the money list, though he is exempt through the 2013 season for his win at last year’s Bob Hope Classic.
One shot behind Vegas is Charles Howell III, while Jeff Maggert is another stroke back at 4 under.
