Bill Haas shot a four-under par 67 in the third round of the Valspar Championship on Saturday to take the lead on the Copperhead Course at the Inverness Resort in Palm Harbor, Fla.
Haas, seeking his seventh PGA Tour victory, is attempting to play consistently well rather than periodically.
"The best players play good all the time and I'm happy if I can just plug along and be up there towards the top every now and then," said Haas. "My goal is to be there more often and so far this year it's been a little bit of a struggle - some good weeks, some bad - and the ball-striking still is just not quite where I would like it."
Canadian Graham DeLaet, still in search of his first PGA Tour victory, shot a three-under 69 to move into second place, one shot behind Haas.
Defending champion Jordan Spieth, who began the tournament with a five-over par 76, has rebounded with a four-under par 67 on Saturday, following a three-under 68 on Friday. Spieth has moved into a tie for ninth, six shots off the lead.
Patrick Reed, No. 10 in the World Ranking, also remains within striking distance, tying for fifth with Charles Howell III and second-round co-leader Steve Stricker, four shots off the lead. Reed shot a three-under 68, while the 49-year-old Stricker had a one-over par 72 in bidding to win for the first time since 2012.
