David Toms birdied the last hole for a tournament record, nine-under-par 61 to move into a share of the Sony Open lead with fellow American Chad Campbell after the third round.

Campbell, co-leader overnight, fired an eight-birdie 62 to sit level with Toms at 14-under 196.

The pair, playing in the final group with 1996 champion Jim Furyk, matched each other with sparkling approach play and ice-cool putting.

American journeyman Shane Bertsch was a distant seven strokes back in a share of third place with Bubba Watson. Bertsch carded a 63 and Watson a 66.
