Dufner has another 65 and opens big lead at Memorial

Zach Johnson dug deep to make the cut on the number with four birdies on his last five holes.

Dufner then produced the shot of the tournament so far, knocking a sweet second to 18 and pitching it pin high before his ball rolled towards the rear fringe and then back down the slope and into the middle of the cup.

Rookie Brett Coletta has demonstrated his pedigree as Australia's next US PGA Tour star with two gutsy rounds at the Memorial Tournament in Columbus, Ohio.

With the 36-hole scoring record, Dufner can look to the weekend as he aims for his first victory since the CareerBuilder Challenge at La Quinta in January 2016.

"I was kind of giving it up there for a while and then wasn't really excited about playing the Presidents Cup here, but figured it was a team event so I'd probably be okay", Dufner admitted.

Summerhays is not a household name, but he worked his name onto two major leaderboards previous year at the U.S. Open (T-8) and PGA Championship (solo third). He has made 30-of-32 putts inside of 10 feet through two rounds.

"It was a good week for me going forward on this golf course", Dufner said.

First-round co-leader David Lingmerth of Sweden tumbled down the leaderboard after a 74. I picked some of the guys' brains on the team that year - How do you play these holes? Some days I'm better with it than others. "I have no idea what will happen ... but I can only control what I can control, continue to have the swing thoughts I've been having, stay calm inside, and continue to play my game".

"Every time I've showed up here I've had good feelings about this place. But fan-wise you wouldn't really see that, the way he carries himself is pretty chill and mellow".

Jason Day did well to make the cut as he recovered from his opening 75 with a battling 71, although at two over, the world No 3 will head into the weekend 16 strokes behind Dufner.

Upstaging better-known countrymen Adam Scott and Jason Day, Coletta backed up his opening 72 at Muirfield Village with a three-under-par 69 to sit well inside the projected cutline of two-over. I have been playing quite nicely recently, but just not quite putting it all together. "Now, it's one of the events that I don't really want to miss and I feel like I can play well".

Top-ranked Dustin Johnson, who struggled to a 78 in the first round, was still six-over through six holes of his second round and in danger of missing the cut, projected to be at two over par.

Italy's Renato Paratore (72) was second, and France's Benjamin Hebert (71) and Englishmen Graeme Storm (68) and Max Orrin (73) followed at 5 under.
