When Phil Mickelson leads heading into the final round of a Major, it usually means the popular American lifts the trophy come the end of the day.
Lefty has won three of his four Major titles after leading through 54 holes, and he is 9/4 to finally become the Bride of the US Open after five runners-up finishes.
Three birdies on the back-nine yesterday saw Mickelson card a par of 70 and hold a single-shot lead at one-under from Hunter Mahan, Charl Schwartzel and Steve Stricker in Pennsylvania.
Mahan could attract some attention at 7/1 after posting successive rounds of 69, and the 31-year-old may well have been leading at this stage but for a double bogey at the 18th on the opening day.
South African Schwartzel has been a model of consistency throughout a tournament which has seen many of his competitors hit some very lofty highs and equally deep lows.
Rounds of 70, 71 and 69 suggest a price of 9/2 for the 28-year-old may prove tempting.
Stricker has shown similarly steady form, holing 15 pars in his third-round of 70. The Wisconsin man is 7/1 for a first Major title, but the 46-year-old would be the oldest first-time Major winner in history, and the oldest ever US Open champion.
A double-bogey at the last for Luke Donald saw him card a third-round 71, but he is still just two shots off the pace and can be backed at 8/1.
Those looking for an outsider to climb the leaderboard on the final day might cast an eye over Rickie Fowler, who has shown some scintillating if inconsistent golf this weekend.
Par on the opening day was followed by a dismal six-over 76 on Friday, before Fowler hauled himself back into the reckoning with a third round three-under 67.
The Florida resident is four shots off the lead, but can be backed at 33/1 to claim a dramatic first Major title.
