What it means: Dufner opened with a pair of 65s and set the 36-hole scoring record at the Memorial. He went into the weekend with a five-shot lead, but he started the final round four behind Summerhays after a shocking 77 on Saturday. But Dufner knew he still had a great chance to win, and he proved it on Sunday with four birdies and no bogeys on the back nine at Muirfield Village. Tied with playing partner Fowler heading to the par-5 15th, Dufner made birdies on 15 and 17 to take control of the tournament. After a second weather delay, Dufner came out and played a nervy closing hole. But he slammed home a 32-foot par putt on 18 to secure the win, and he joined tournament host Jack Nicklaus as the only Ohio-born champions of the Memorial.
Round of the day: Anirban Lahiri went out early and posted a bogey-free 65 to grab a share of second place. Lahiri needed a good week coming off of three straight missed cuts.
Best of the rest: Fowler played a solid front nine with three birdies and no bogeys, and he held the lead for a short time after another birdie on the par-5 11th. He was unable to capitalize on the par-5 15th after a bogey at the short par-4 14th, and Fowler made a closing bogey to drop back into a share of second place.
Biggest disappointment: Summerhays started the day with a three-shot lead and had a great chance to win his first PGA Tour title. But after a double on No. 3 and a bogey on 4, he started to wobble. Birdies on Nos. 5 and 7 got him back in the mix, but Summerhays came home with three back-nine bogeys and another double at 18 for a 78 to finish T-10.
Shot of the day: Dufner found the right rough off the 18th tee, and he tried to hack out of the thick stuff but advanced his second shot only 75 yards. His third shot from the rough landed on the green 32 feet away from the hole. That’s when Dufner stepped up and drained his longest putt of the week to win the title.
