Robert Garrigus, the big-hitting Idahoan who broke through with his first PGA TOUR victory during the Fall Series last year, is the sixth player to reach 12-under par this week at TPC Summerlin. With four birdies in his first five holes Saturday, Garrigus reached that number and is one shot behind leader Kevin Na, who got to 13 under with a birdie on the opening hole. Garrigus is currently tied with Paul Goydos, Kris Blanks, Jhonattan Vegas and Charlie Wi for second. There are 20 players at 10-under par or better and 42 at 8 under or better.
