Robert Streb became the 28th player to ever shoot a 63 at a Major – but the third in just 16 days – allowing him to tie fellow American Jimmy Walker atop the leaderboard at the end of the second round of the PGA Championship Sunday in New Jersey.
The two men are tied at 9-under, two strokes ahead of world No. 1 Jason Day and Argentine Emilliano Grillo.
Streb climbed from tied for ninth to tied for first by notching eight birdies and a bogey on the day. He hit 63 with the TV broadcast at a commercial as most fans were similarly distracted by the runs being put on by Day and Patrick Reed.
Walker shot a 4-under 66 on the day and would have had the lead had he not slipped up and bogeyed No. 18 after hitting three straight birdies on 12, 13, 14 earlier in the round.
Day looked like he would fall totally out of contention early, 2-over through seven holes after double-bogeying No. 7. But the Aussie turned things around with birdies on 8 and 9 to get back to even, then rattled off five birdies in six holes, including four straight between holes 10 and 15 to fight his way to a 65.
Grillo also caught fire on the back nine, going 1-over on the first 11 then -4 on the final seven. Lurking one shot further back is Henrik Stenson, trying to win back-to-back Majors. Stenson was 3-under for a second straight day shaking off back-to-back bogeys on 12 and 13 with an eagle on 18.
Three players ended the day at 5-under: Martin Kaymer, Reed, and Brooks Koepka. In all, 19 players are within six strokes or fewer of the lead with half the tournament to play, including former No. 1s Jordan Spieth and Adam Scott, part of a glut tied for 13th at 3-under.
