Golf: Streb shares PGA lead

Unheralded Robert Streb fired a record-equalling 63 to share a two-shot lead with Jimmy Walker after the second round of the PGA Championship on Friday, with heavyweights Jason Day and Henrik Stenson lurking nearby.
Streb, who has one PGA Tour victory, rolled in a 20-foot birdie putt on his last hole, the ninth at Baltusrol, for the 30th round of 63 ever shot in a major championship.
He joined fellow American Walker (66) at nine-under 131.
"Most of the year has been a big struggle," said 29-year old Streb, who won the McGladrey Classic two years ago but has missed nine cuts this year including the Masters, US Open, British Open and The Players. "Felt like I kind of found something with my golf swing the last two weeks. Starting hitting it kind of solid ... and obviously made a bunch of putts today."
Walker, winless this season after winning three tournaments in 2014 and two more last year, also emerged from nowhere, after finding his putting stroke, notwithstanding his sole bogey of the day on the par-five 18th.
