SPRINGFIELD TOWNSHIP, New Jersey — Robert Streb became the 30th player in history to shoot a 63 in a major tournament and is tied for the lead with Jimmy Walker at 9-under-par 131 after Friday’s second round of the 98th PGA Championship on the Lower Course at Baltusrol Golf Club.
Streb rolled in a 21-foot birdie putt on No. 9, his final hole, to achieve the milestone. The 131 for Streb and Walker matches the lowest 36-hole score in PGA Championship history.
Top-ranked Jason Day shot a 5-under 65 and Emiliano Grillo of Argentina had a 67 and are two shots back, tied for third at 133.
British Open winner Henrik Stenson of Sweden shot a second consecutive 67 to claim sole fifth at 134.
Streb, the world’s No. 74 ranked player, sank eight birdies opposite a bogey on No. 16. The 29-year-old has zero top-10 finishes in 23 starts this season and has missed nine cuts.
Walker, the 18-hole leader, briefly ceded the lead after Grillo birdied four of his first nine holes, but the 37-year-old American rolled in five of his own from Nos. 5 to 14.
The 48th-ranked Walker led by as many as three strokes before finishing at No. 18 with a bogey, only his second through two rounds.
Walker is a five-time winner on the PGA Tour but has never won a major tournament.
Day dropped seven birdies in eight holes from Nos. 8 through 15 and Grillo had four birdies and one bogey on the day.
Stenson, the world’s No. 5 ranked player, got off to a rocky start with back-to-back bogeys on Nos. 12-13 — his third and fourth holes, respectively.
However, the 40-year-old eagled the par-5, 554-yard No. 18 and sprinkled three birdies through his final nine holes.
Third-ranked Jordan Spieth carded a 67, moving into a tie for 13th at 137.
The 23-year-old Dallas, Texas, native was sharp early with five birdies opposite one bogey on his first nine holes but cooled off with a bogey and eight pars to close.
Reigning U.S. Open champion Dustin Johnson couldn’t recover from an opening-round 77, shooting a 72 to wrap up his weekend at 9 over.
The second-ranked Johnson had made 25 consecutive cuts in PGA Tour events, which was the longest active streak on the tour.
Phil Mickelson put his opening tee shot on a nearby street en route to triple-bogeying No. 1.
The 46-year-old left-hander bounced back with four birdies, including one on No. 18, to put himself above the 2-over cut line in a tie for 61st at 1 over.
Fourth-ranked Rory McIlroy missed the cut after bogeying No. 18. He finished at 3 over, tied for 87th, despite a second-round 69.
