If Jason Kokrak secures his first PGA Tour victory this weekend at the Valspar Championship, he'll look back on his hole-in-one on Saturday as one of the biggest highlights of his career. There's a lot of golf to be played, but an ace at the 15th hole on the Copperhead course at Innisbrook gave Kokrak a share of the lead late in his third round. Kokrak was 3-under on his third round through 14 holes as he stepped up to the 219-yard 15th hole, sitting two behind the lead, about to enter one of golf's toughest closing stretches.
