Bill Haas had a triple bogey, and Andres Romero and Roberto Castro carded doubles, but they all still wound up in a four-way tie for the lead Saturday in the AT&T National in Bethesda, Md., with James Driscoll, whose third round was pleasantly dull by comparison.
Castro put the perfect finishing touch on this most wild day at Congressional when he hit his approach into the water left of the 18th green, and then chipped in for par from 80 feet to salvage an even-par 71 and keep a share of the lead at 7-under 206.
Haas made nine birdies and had to settle for a 68, courtesy of two wedge shots that cost him four shots, including his triple bogey on No. 11.
Romero had a three-shot lead at one point, and then it was gone. He went from the water to a bunker on the 11th for double bogey and followed that with a bogey on the next hole.
Meanwhile, Driscoll, of Brookline, Mass., motored along without too much excitement. He had a 68, the only player in the field to break 70 all three rounds. Coming off a bogey on the 15th, Driscoll thought he might be headed for another with a poor tee shot. But he knocked a 4-iron out of the rough, barely got onto the green, and rolled in a 25-foot birdie.
Ten players were separated by four shots going into the final round, a group that includes 19-year-old Jordan Spieth. He had a two-shot lead after opening with two straight birdies, and then went through a stretch of missing five putts inside 8 feet on a four-hole stretch. One of them was a three-putt from 5 feet for double bogey on No. 8.
Champions — Fred Couples birdied three of the final five holes for a 3-under 67 and a two-stroke lead after the third round of the Senior Players Championship in Pittsburgh.
Couples, 53, completed a 62 in the morning and had a 15-under 195 total.
Kenny Perry was second, finishing a 63 in the morning and backing it up with another 63 in the afternoon.
European — Joost Luiten moved to 13 under and remained one ahead of Pablo Larrazabal after both players shot bogey-free 6-under 66s heading into the final round of the Irish Open in Maynooth.
