Peter Hanson leads the 2012 US Masters heading into the final day of play at Augusta National, but Phil Mickelson is just one shot behind, while a number of players are in contention to make a challenge on Sunday.
Mickelson shot a six under par round of 66 on Saturday to put him well in contention, and he is the bookmakers' favourite to win what will be a fourth Green Jacket on Sunday evening.
But it is Hanson who leads after three rounds, with the Swede carding a seven under par round of 65 on Saturday - the best of the week so far - to move him from two under to nine under par.
2010 Open champion Louis Oosthuizen is also well in contention, with the South African seven under par after three rounds, while American trio Bubba Watson, Matt Kuchar, and Hunter Mahan are all well placed at six, five, and four under par respectively.
Europe are represented on the leaderboard by Padraig Harrington, Lee Westwood and Henrik Stenson, who are all four under par ahead of Sunday's final round.
