Miami, March 15:

Americans Phil Mickelson and Nick Watney share the same instructor, and they also shared the lead after the third round at the CA Championship on Saturday.

Butch Harmon-coached Mickelson and Watney traded the lead back and forth before ending the day locked at 16-under-par 200 at Doral Resort’s Blue Monster. Of the two, Watney was most satisfied after a five-under 67, while Mickelson thought he could have gone a bit lower than three-under 69.

They headed Indian Jeev Milkha Singh (68) and Colombian Camilo Villegas (69) by four strokes with one round left in the $8.5m World Golf Championships event. Tiger Woods improved to equal 19th with a tidy 68, but was nonetheless out of contention, nine strokes behind.
