PEBBLE BEACH (AP) — Paul Broadhurst shot a 6-under 66 at Pebble Beach on Friday to take a two-stroke lead after the first round of the PGA Tour Champions’ Nature Valley First Tee Open.The 51-year-old Broadhurst won the Senior British Open at Carnoustie in July for his first victory on the 50-and-over tour. He won six times on the European Tour and played in the 1991 Ryder Cup.With the seniors playing alongside boys and girls from The First Tee programs throughout the country, Broadhurst had 6-under 30 on the front nine in his first professional round at Pebble Beach.“Actually, hit the flag on my second shot on the first,” Broadhurst said. “Could have gone in, I guess, but rolled 6 feet.”He cooled off on the back nine, making two birdies and two bogeys.“Front nine, I played really well, as good as I’ve played since winning the British to be honest.
