Notebook: Day 4 at the PGA Championship

Brooks Koepka: The third-year pro improved his score in each round and closed with a 6-under 66, tying for low round of the day and moving him from 13th place into a tie for fiifth.

Martin Kaymer: The 2010 champion was poised to contend, but nullified a birdie on No. 3 with a double-bogey on the next hole and spun his wheels from there, dropping to 12th place. At 73, he was the only player in the top 10 entering the round to shoot above par (73).

Rory McIlroy: He reported no discomfort with his ankle after his final round, in his first competition since hurting the ankle playing soccer. He shot 69 and finished at 9-under 279, in 17th place.

Steve Stricker, the 48-year-old from Madison, Wis., walked up to the 18th green to the sound of fans in the grandstand cheering loudly and chanting his name.

"I don't get that too often, and that was special for me," Stricker said after rolling in a 9-foot par to finish at 4-under 284 for the championship, with a 2-under 70 on Sunday. "I really appreciate the support I get here and around the country. I hear Wisconsin fans wherever I go."

Stricker had a little run with birdies at 10, 11 and 12, and was thinking he might be able to sustain it. "It was close to being something special," he said.

• Brian Gaffney, a New Yorker and the only club pro among 20 entries to make the cut, went off in the first group and birdied the final hole for a closing 1-under 71, finishing 5 over for the championship.

• Those who quit following Dustin Johnson after he clunked a quadruple-bogey 8 on the first hole missed a rally in which he played the final 17 in 7 under in a final-round 69.

• Justin Rose got within two shots until making a double bogey for the third straight day. He closed with a 70 and finished fourth.

Par-4, 397-yard No. 14: Coming off a birdie to pull within three shots, Jordan Spieth was in the fairway and pulled a wedge over the green. Jason Day was in a fairway bunker, hit out to 10 feet and made birdie to build a four-shot lead with four holes to play. Day won by three strokes.

"So if some guy was allergic to ants and he got an ant on him, you could care less?"

— Bubba Watson, pleading in vain for relief from a rules official after a drive on No. 5 wound up on an ant mound

"Jordan Spieth lost. By lost I mean pushed his earnings to over $10 million this season and became No. 1 in the world. May we all be losers."
