NEWTOWN SQUARE, Pa. -- At five straight weeks on the road, this is the longest Patrick Cantlay has ever been away from home. After shooting 70-67 the first two rounds at Aronimink, that time away has only gotten longer with Cantlay in the top 25 heading into his third round here at the AT&T National.

The 19-year-old’s last few weeks have been pretty remarkable -- he finished as the low amateur at the U.S. Open, where he tied for 21st, shot a course-record 60 at the Travelers Championship, where he was the 36-hole leader before finishing in a tie for 24, and he’s on the fringe of contention here.
