Knox leads Pebble Beach Pro-Am

Scotland's Russell Knox held the clubhouse lead at the AT&T Pebble Beach National Pro-Am after an impressive opening-round 64 in California.

Knox's six-under total included eight birdies and two bogeys on the Monterey Peninsula course.

America's Scott Langley was also on six under, having completed 15 holes of the Monterey Peninsula course, while compatriot Hunter Mahan was on the same mark after 15 holes of the Pebble Beach Course.

South Korea's Noh Seung-yul had looked set to take the clubhouse lead as he led on seven under with two holes left to play of the Shore Course, but bogeys on his final two holes dropped him to five under.

Matt Every (Pebble Beach) joined Noh in a share of second place in the clubhouse, while Ted Potter Jnr was on the same mark through 17 holes on the same course.

England's Lee Westwood signed for a 68 at the end of his round on the Pebble Beach course.
