Americans on the charge as Woods fires

Tiger Woods had the joint best round of the day, but it was two fellow Americans who were leading the race for the WGC-Cadillac Championship as it entered the closing stretch in Miami tonight.

Nick Watney and Dustin Johnson, who had both failed to break 80 when leading majors with a day to go last season, were level on 15 under par with four holes to go in the second of this year’s world championships.
