PALM HARBOR, Fla. (AP) -- Adam Hadwin of Canada made two long birdie putts on the back nine and had a 4-under 67 to extend his lead to four shots in the Valspar Championship as he goes for his first PGA Tour victory.
More than two big birdies, Hadwin kept a clean card Saturday on the Copperhead Course at Innisbrook.
He was at 14-under 199, with Patrick Cantlay four shots behind. Cantlay, a promising amateur who missed the last two years with a back injury, had a 66 and will play in the final group in just his second tournament this year.
Jim Herman had another 71 and was five shots behind.
Hadwin shot a 59 in the CareerBuilder Challenge in January for a two-shot lead going into the final round and was runner-up.
