No one crashed harder than Patrick Reed, who had a two-shot lead to start the final round, still had a two-shot lead at the turn and didn't even finish in the top 10. He made back-to-back double bogeys, shot 41 on the back and closed with a 77 to tie for 11th.
"This definitely burns and definitely gets me more fired up for more events coming up," Reed said.
Even though he got a reprieve with the clutch bogey putt, Rose looked like a U.S. Open champion the way he put himself into position. He hit 5-iron to 5 feet for one of only four birdies on the 11th hole Sunday. Staring at potential bogey from deep rough on the 14th, he boldly hit 3-wood up the hill and between the deep bunkers to the middle of the green. It was a par, but Rose called the 3-wood his "shot of the day."
And before his blunder on the 18th, he holed an 8-foot sliding par putt on the 17th.
"I felt like all aspects of my game were tested this week, and it's really nice to win in that fashion," Rose said.
Stefani, whose only major experience was at Merion last year, plodded along like a U.S. Open veteran with one par after another. He joined Rose in the lead with a 15-foot birdie putt on the 16th.
So many others fell back.
Brendon Todd was tied for the lead until a double bogey in the water on the 10th. Marc Leishman three-putted for bogey on No. 7 and made bogey on the easiest par 4 at Congressional. Brendan Steele made a late rally, only to take on too much from the rough on the 18th and find the water for double bogey.
This was the first British Open qualifier on the PGA Tour — the leading four players not already exempt from the top 12 at Congressional get into Royal Liverpool next month.
Stefani earned one spot as the runner-up. Charley Hoffman (69) and Ben Martin (71) each birdied two of the last three holes to tie for third. Steele got the last spot with a 71 that put him in a three-way tie for third with Andres Romero and Todd, who already is exempt. Steele earned the spot over Romero because he has a higher world ranking. Romero closed with a 68, the low score in a final round when the scoring average was 73.7.
