( CNN ) -- Sweden 's Peter Hanson will take a one shot lead into the final round of the Masters after posting a seven-under par round of 65 at Augusta National on Saturday . The 34-year-old made a late charge up the leaderboard with birdies at four of the last five holes to eclipse the efforts of home favorite Phil Mickelson . Hanson , who is playing in only his second Masters , said he will have to manage his emotions on Sunday . `` This is kind of a new situation to me , being in the spotlight like this , and playing the last group , '' Hanson said . `` So it 's going to be about controlling my emotions and trying to be in the present and trying to play the same kind of golf that I 've been doing today . '' Mickelson , a three-time Masters champion , was also in scintillating form on the back nine taking just 30 strokes . Birdies at the par four 10th and the par-three 12th were followed by an eagle at the par five 13th which sent the Augusta crowd into raptures . Further excitement followed at the 15th as Mickelson claimed a birdie four with another coming at the 18th to leave the 41-year-old on eight-under par and in pole position to claim the fifth major title of his career . South Africa 's Louis Oosthuizen is one shot further back after a composed round of 69 while playing partner England 's Lee Westwood had to settle for an even-par round of 72 which leaves him in a tie for sixth on four-under par with Sweden 's Henrik Stenson ( 70 ) . America 's Hunter Mahan and Ireland 's Padraig Harrington are also four-under after both men shot rounds of 68 on Saturday . Bubba Watson continues to creep up the leaderboard after another sub-par round ( 70 ) moved him up to fourth place . Compatriot Matt Kuchar also shot 70 to finish one shot further back on five-under par . Overnight leaders Fred Couples and Jason Dufner could n't keep pace with the fireworks of the leaders . Both men finished with three-over par rounds of 75 to drop into an eight-way tie for 11th place . Rory McIlroy is out of the running after posting a third round 77 . A double bogey at the first was the first of six dropped shots on the opening nine with another coming at the long par-four 11th . The Northern Irishman clawed back a couple of shots , and nearly holed his approach to the 18th , but at one-over par for the tournament is too far back to mount a challenge . His playing partner , Spain 's Sergio Garcia also had a disappointing day posting a three-over par 75 to leave him one-under after three rounds . Tiger Woods is also out of contention after another even par round of 72 left him 12 shots off the lead . `` I did n't play that badly . It was so close to being a really good round of golf . I did not play the par-fives that well . I just did n't take care of the opportunities when I had them , '' Woods said .
