The 59 watch is officially on at TPC Summerlin. Hunter Haas is 10 under through 14 holes today in Las Vegas and in position to become the sixth player in PGA TOUR history to shoot 59 -- or possibly the first to best it. TPC Summerlin is a par-71 layout, meaning 2 under over the last four holes (and 12 under total) would be enough to reach the milestone number. Ahead of Haas are par 4s at Nos. 6 (430 yards) and 7 (382 yards), the 239-yard par-3 8th and the 563-yard par-5 9th. No. 8 played as the second-toughest hole on the course, with just five birdies and 30 bogeys posted in Thursday’s opening round. The par-5 9th was the second easiest in Round 1, surrendering 61 birdies and nine eagles. Click here to track Haas live, shot-by-shot
