Bill Haas took a swing tip from his father on Tuesday and converted it into a 54-hole lead at the Valspar Championship.

Haas atoned for a three-putt bogey on the 13th by chipping in for birdie from behind the 15th green on his way to a 4-under 67 on Saturday at Innisbrook in Palm Harbor, Fla., giving him a one-shot lead over Graham DeLaet of Canada going into the final round.

Jay Haas, a nine-time PGA Tour winner and the Presidents Cup captain the last two times, had a week off from the PGA Tour Champions and spent three days with his son. It was on the par-5 fifth hole during a practice round that the father suggested Haas use a more abbreviated follow on his swing to get his hands moving fasters.

It seems to have worked.

On a Copperhead course that has yet to yield a round lower than 66, Haas put together his second straight 67 to reach 8-under 205. Although he has fashioned a pair of top 10s this year, Haas has not seriously contended or made a mark since last October when he won the decisive point in the Presidents Cup with his father as captain.

‘‘Half of it is these guys are really good,’’ Haas said. ‘‘I’m trying to beat some really good players and they’re beating me right now. I just haven’t been sharp. When the Presidents Cup was won, being in the last match and handling some pressure, that was a great stepping stone for me.

“Hopefully, it will lead to better things. But I’ve still got to play well tomorrow.’’

DeLaet, now sporting a beard that would make Old Tom Morris proud, pounded a shot out of the rough and over the water to 3 feet on the par-5 14th for an eagle that shot him up the leaderboard. He finished with a 68 to get into the last group.

It’s still up in the grabs on Sunday because of the nature of Innisbrook, which takes shots away more often than it gives up birdies. Six players were within four shots of the lead, and even Jordan Spieth believes he is still in the mix.

Spieth, who opened his title defense with a 76, made the cut with one shot to spare on Friday and moved into a tie for ninth on Saturday with a bogey-free 67 in which he holed a long eagle putt and made a pair of key par saves coming in.

‘‘To think after the first round that I go Saturday night be able to sleep with a chance to win the golf tournament, I’m very pleased,’’ Spieth said.

Charley Hoffman (67) and Ryan Moore (69) were three shots behind.

Charles Howell III three-putted from 70 feet on the closing hole for a 70.

Steve Stricker, who shared the 36-hole lead with Will MacKenzie, shot a 72. He also was 4-under 209, along with Patrick Reed (68), whom Spieth beat in a playoff last year at Innisbrook.

Asian — Scott Hend of Australia shot a 70 to retain a two-shot lead over American Peter Uihlein after the third round of the Thailand Classic in Hua Hin.

Hend produced five birdies for a three-day total of 14-under-par 202.

Uihlein, the first-round leader, had four birdies for a 69 and 12-under-par 204.

Belgium’s Thomas Pieters scored the lowest round, a bogey-free 66 for a total of 205.
