PITTSFORD, N.Y. (AP) — Justin Rose watched Adam Scott shoot 30 on his front nine Thursday, so he outdid his friend with a 29 on the back nine Friday at the PGA Championship.Seems only appropriate for two guys born a couple of weeks apart who have followed similar paths ever since.At the start of 2013, neither had a major title. Now both have the chance to become the third player in the last 15 years to win two in a season.Scott, the Masters champion, headed into the weekend at 7 under, two strokes behind leader Jason Dufner. Rose, the U.S. Open champ, was 6 under.“I was hungry before the Masters, and I might even have a bigger appetite after it,” Scott said after a 68 on Friday.
