Tiger Woods and Phil Mickelson both birdied the par-five second hole in their Sunday showdown at the U.S. Masters to share the lead at 12-under-par.
Woods just missed making an eagle with his putt from the fringe, while Mickelson blasted out of the front left bunker to eight feet and converted the putt for his birdie.
Woods had bogeyed the first hole to find himself in a four-way tie for the lead in the final round of what could prove to be an historic Masters.
The world number one, who began the day with a one-shot advantage over world number two Phil Mickelson, hit his approach shot through the green, chipped boldly past the hole and two-putted for bogey to drop to 11-under-par.
Mickelson missed a makeable birdie putt to remain at 11-under, and the two were joined at that figure by 1989 British Open champion Mark Calcavecchia and Angel Cabrera of Argentina.
Calcavecchia birdied the first hole to reach 11-under, while the big-hitting Cabrera birdied his first two holes to join the log-jam at the top.
Woods is aiming to become the first player to win four professional majors in a row after winning the last three majors of the 2000 season - the U.S. Open, the British Open and the PGA Championship.
Jim Furyk surged to 10-under-par with four birdies in his first seven holes as Augusta National Golf Club, whose greens were softened by heavy rain earlier in the week, was again vulnerable to attack.
David Duval joined Furyk at 10-under with birdies at the second and third holes after opening with a bogey. -REUTERS-
