Phil Mickelson made a second-nine charge on Saturday at Augusta National to position himself for a fourth Masters title.
Mickelson shot 30 on the final half of his third round to cap off a round of 6-under 66 to trail Swede Peter Hanson by a shot. With a birdie at the last for a third consecutive day, Mickelson closed at 8 under par.
Hanson, playing in his second Masters, also made a tap-in closing birdie to finish off a tournament-best 65. After an opening bogey, Hanson made eight birdies without dropping another shot.
The two will be in the final group on Sunday, which has produced the Masters winner in 18 of the last 20 years. Mickelson will be in the final group on Sunday for the fourth time in the last nine years.
The pair also have history in the Ryder Cup, with Mickelson posting a 4-and-2 win over Hanson at Celtic Manor in the singles session in 2010.
Hanson leads 2010 British Open champion Louis Oosthuizen by two shots, aided by three consecutive birdies to end the first nine en route to 3-under 69.
Bubba Watson closed with a birdie at the final hole to trail by three shots, alone in fourth place on 6 under. Matt Kuchar is solo fifth at 5 under.
Padraig Harrington made birdie on five of the last six holes to shoot 68 and reach 4 under for the championship. He is tied with Lee Westwood, whose 72 has him trailing Hanson by five shots.
36-hole co-leaders Jason Dufner and Fred Couples stumbled in the third round.
Bogeys on the first two holes soured the chances of the ’92 champion as Couples heads into Sunday at 2 under after shooting a 75. Dufner finished up with three putts at No. 18 to card a 75 of his own, and faces a deficit of seven shots entering the final round.
Tiger Woods shot a third-round 72 on Saturday, entering the final round behind by a dozen shots at 3 over. He failed to birdie a single par-5 for the second consecutive round and just the fourth time in his Masters career.
Rory McIlroy is a shot ahead of Woods, going backward on Moving Day. The Ulsterman shot 5-over 77 on Saturday, somewhat salvaged by a closing approach to inches for a tap-in birdie.
Playing partner Sergio Garcia shared in the misery, posting 75 on Saturday to fall eight behind the pace.
The pair shared a hug at the par-3 12th after both players managed birdie in the middle of Amen Corner.
Garcia was matched by world No. 1 Luke Donald, who fell to 7 over for the tournament.
