DUSTIN JOHNSON’S defence of his Pebble Beach National Pro-Am title remained on track as he entered the final round tied for the lead and four strokes clear of the field alongside Paul Goydos.

Johnson and Goydos, who completed eight-under-par 64s on Saturday, were in a share of the lead alongside four others at the halfway point, but moved to 18 under in the third round to tee up a final-round shootout at Pebble Beach.

Bryce Molder, JB Holmes and Matt Jones were leading the chase on 14 under, while Alex Cejka was alone in sixth place, five strokes off the pace.

Pádraig Harrington shot a level par 72 yesterday to finish on nine under.
