(AP) -- David Mathis had a hole-in-one and shot a 6-under 64 on Thursday to take a one-stroke lead after the first round of the Travelers Championship.
The 38-year-old Mathis, who missed the cut last week in the U.S. Open, began play on the back nine, making a birdie on 10 before holing out from 158 yards shot on the par-3 11th hole.
He was 6 under after six holes.
Nathan Green, Will Claxton and defending champion Fredrik Jacobson shot 65 on a day that saw temperatures soar into the upper 90s.
U.S. Open champion Webb Simpson and Masters winner Bubba Watson played together and finished in a group of 10 at 66.
The third member of the threesome, PGA champion Keegan Bradley, shot a 68.
