Summerhays tops at Memorial after Dufner skies to 77

DUBLIN, Ohio — Daniel Summerhays shot a 4-under-par 68 that took him from a five-stroke deficit to a three-shot lead in the Memorial on Saturday.

More than his solid round was a collapse by Jason Dufner, who lost his lead with four consecutive bogeys on the front nine and two balls in the water on the back nine for a 77. Dufner went from the 36-hole record to four strokes out of the lead.

Summerhays was at 13-under 203.

Matt Kuchar, who won the Memorial four years ago, ran off three consecutive birdies on the back nine and shot a 67 that gets him in the final group with Summerhays as he tries to end 82 PGA Tour starts without a victory.

“Today was pretty pathetic on all accounts, so have to play better tomorrow,” Dufner said.

Taking the week off, Jutanugarn replaced Lydia Ko atop the ranking when So Yeon Ryu missed the cut. Creamer and Kim each shot 4-under 67 to reach 9 under.

• Phil Mickelson said he will miss the U.S. Open for the first time in 24 years to attend his oldest daughter’s high school graduation in California. Mickelson hasn’t officially withdrawn from the U.S. Open, which starts June 15 at Erin Hills in Wisconsin. But that is the same day as Amanda Mickelson’s graduation from Pacific Ridge School, and he doesn’t see any way he will make a tee time. The U.S. Open is the only major Mickelson has not won.
