GREENSBORO, N.C. — Beau Hossler handled a half-dozen tough par putts and two rain delays Saturday for a 4-under-par 66 that gave him a share of the lead with Michael Brennan going into the final round of the Wyndham Championship with postseason berths at stake. Brennan, who went from the PGA Tour Americas to a PGA Tour card by winning the Bank of Utah Championship last fall, made a birdie putt from 15 feet on the last hole for a 63. He hit his tee shot into the rough on the 17th, and then came another delay of 1 hour, 20 minutes. “That might be the hardest two-putt on the PGA Tour right there,” Hossler said of the 18th green. 1 player in the PGA Tour University ranking who made his pro debut in June, has to win and he started one shot out of the lead and in the final group with Hossler.
