Jim Furyk and Louis Oosthuizen both made perfect starts to the final round of the World Golf Championship-Bridgestone Invitational.
With American Furyk just one ahead of the Masters Tournament runner-up overnight, Oosthuizen immediately eradicated the deficit with a 15 foot birdie at the first.
The South African was level for just a seconds though, as Furyk followed him in from five feet before both players birdied the long second.
At 13 and 12 under par they were well clear of Northern Ireland’s Rory McIlroy, who birdied the second and third to move into third place on eight under.
A storm delay had earlier pushed the leaders’ tee times back to 12:44 local time.
Furyk completed a hattrick of gains at the third, and when Oosthuizen missed a five footer for par at the fifth the gap at the top had suddenly grown to three.
Furyk had his first bogey of the day at the sixth, and Oosthuizen looked in trouble too; but the former Open Champion parred from 12 feet to reduce the gap to two.
