NEWTOWN SQUARE (AFP) — Americans Maverick McNealy and Alex Smalley shared the lead after Friday’s chaotic second round of the PGA Championship as cold, windy conditions contributed to carnage at Aronimink.

Six others were only one adrift after 36 holes with seven more, including top-ranked defending champion Scottie Scheffler, just two strokes off the lead entering the weekend.

McNealy, never in the top 25 after 36 holes in 14 prior major starts, fired a three-under par 67 to match Smalley on four-under 136 at the midway mark.

“This is unfamiliar territory to me,” McNealy said. “I was surprised to be that high on the leaderboard.”

McNealy, a back-nine starter whose best major finish was 18th at last month’s Masters, holed out a 54-foot bunker shot for eagle at the par-five 16th, then made birdie putts from 12 and 18 feet on the first two holes.

The world No. 33 squandered the solo lead, however, with three-putt bogeys at the sixth and par-three eighth holes.

“My putter is going to have to be my best club,” McNealy said. “That’s the reason I still have a job out here.”

Smalley fell out of the solo lead with three bogeys in a row but a closing birdie put him on 69.

“It was difficult, it was chilly this morning, the wind was up,” Smalley said. “Some of the pin locations are very difficult. They’re right on the top of a crown.”

Sharing third on 137 were Japan’s Hideki Matsuyama, the 2021 Masters champion, plus Americans Chris Gotterup and Max Greyserman, South African Aldrich Potgieter, Australian Min Woo Lee and German Stephan Jaeger, who made 18 pars.

A bogey-bogey finish doomed 21-year-old Potgieter’s bid to become the youngest 36-hole major leader since Tiger Woods at the 1997 Masters.

“Looking at those last two holes as kind of unfortunate, but I felt like I was in control most of the round,” Potgieter said.

Gotterup closed with three birdies to shoot 65.

“Just really battled all day,” Gotterup said. “It was very hard out there. It was cold. There were some pins it didn’t even look like were on the green.”

Joining Scheffler in ninth on 138 were fellow Americans Cameron Young, Justin Thomas and Harris English plus Spain’s David Puig, Sweden’s Ludvig Aberg and South Korean Kim Si-woo.

Scheffler tumbled from a share of the lead with three bogeys in his first four holes but closed with a birdie at nine to shoot 71.
