CROMWELL, Conn. -- Nineteen-year-old UCLA star Patrick Cantlay shot a course-record 10-under 60 -- the lowest PGA Tour round ever by an amateur -- to take a four-stroke lead Friday in the Travelers Championship.

The low amateur last week in the U.S. Open, Cantlay tied the tournament record set by Tommy Bolt when the event was played in Wethersfield in 1954.

Cantlay birdied the final two holes at TPC River Highlands to reach 13 under. After shooting a 67 on Friday morning in the rain-delayed first round, he had eight birdies and an eagle in the afternoon.

D.J. Trahan (62), Webb Simpson (65), Vaughn Taylor (66) and Alexandre Rocha (66) were 9 under along with Andres Romero, who completed only five holes in the second round before play was suspended because of darkness just after 8 p.m. Seventy-seven players were unable to finish the round.

Cantlay just completed his freshman year at UCLA, and has said he plans to stay until he earns his degree.

Four players have shot 61s at the TPC River Highlands course. The last was Kenny Perry in 2009.

An amateur hasn’t won a PGA Tour event since Phil Mickelson in the 1991 Northern Telecom Open in Arizona.
