CROMWELL, Conn. — 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.

Mathis' ace was the shot of the day. He said he was just trying to cut a 9-iron close to the pin and it hit exactly where he aimed, bounced right and into the hole.

Former UCLA star Patrick Cantlay made his professional debut with a 75 on the same course where he made headlines last year with a second-round 60 as a 19-year-old amateur.
