Sam Burns shot a second round 61 as he took a one-shot halfway lead at The American Express tournament in California.
Burns’ career-low round leaves him on 17 under par, one shot ahead of fellow American Michael Kim with South Korean’s KH Lee and American amateur Nick Dunlap a further shot back.
A pair of eagles and seven birdies had put Burns in with a chance of breaking 60, but he could only par the last two holes.
