One bad swing by Adam Scott led to two balls in the water on the same hole Saturday in the Honda Classic. Even with a quadruple bogey, he managed to be satisfied with a 4-under-par 66 and a share of the lead with Sergio Garcia.

A bizarre and breezy afternoon in Palm Beach Gardens, Fla., ended at PGA National with two players whose fortunes changed mightily in the final hour.

Scott looked better than ever, 7 under through 14 holes and only once having to save par. He was three shots ahead going to the tee on the par-3 15th, and it was starting to look like a runaway. Some 20 minutes later, he was one shot behind Garcia.

‘‘Pretty costly,’’ Scott said. ‘‘But fortunately, I had a couple shots to spare. Hopefully, it won’t cost me too big in the grand scheme of things.’’

Garcia lost the lead with a bogey from the bunker on the 17th, and caught Scott with a short birdie on the 18th for a 67.

They were at 9-under 201.

Blayne Barber had a 69 and was four shots behind.

Rickie Fowler had a one-shot lead going into the third round and was the first player at the Honda Classic to go bogey-free through the opening 36 holes. And then Saturday, he couldn’t make a birdie. Fowler made bogey on the easiest hole at PGA National, the par-5 third, and wound up with a 74 to fall five shots behind.

Scott didn’t seem overly bothered by the quadruple bogey, mainly because of the 17 other holes he played so well.

‘‘I did a lot of things really well today, so it’s exactly the round I needed,’’ he said. ‘‘I need to put one more together tomorrow. It’s going to be an exciting day for me.’’

Jason Bohn told NBC Sports that what was reported as a mild heart attack Friday turned out to be much more. Bohn, 42, complained of chest pains after his round Friday and had a stent inserted Saturday for what he said was 99 percent blockage of a major artery.

LPGA — Lexi Thompson shot an 8-under 64 in the third round of the LPGA Thailand in Chonburi to establish a four-stroke lead over Korean In Gee Chun.

The fourth-ranked American fired nine birdies — against a lone bogey on the 16th — for an overall 16-under 200.

European — Louis Oosthuizen carded a 5-under 67 to take a three-stroke lead after three rounds of the Perth International in Australia.

Oosthuizen had a 54-hole total of 15-under 201. New Bedford’s Peter Uihlein (71) and France’s Romain Wattel (65) were tied for second. Uihlein bogeyed the 18th hole and took six shots on the 148-yard, par-3 12th when he hit his tee shot to the back of the green and struggled to recover before taking two putts to finish.
