Phil Mickelson has finished second in the U.S. Open Championship six times without a victory, but he will have especially passionate support at Pinehurst No. 2 this year as he attempts to win the career Grand Slam.

Callaway Golf, in a promotion called “The Big Bertha Payday,” (#BerthaPayday) is allowing golfers a chance to win the same official dollar amount of Mickelson’s prize winnings at this year’s U.S. Open. Starting today (5/22) and lasting through the final round on June 15, every person living in the United States or Canada that demos a Big Bertha Driver, Big Bertha Alpha Driver, or a Big Bertha Fairway Wood at a participating location will receive a code they can use to enter the contest.

That’s it. Just test out Callaway’s newest Big Bertha technology at a local participating golf course or range, and you could win up to $1.5 million, the estimated winnings for first place.

“A lot of people out there have not had the chance to feel like what a putt for a million dollars feels like,” said Mickelson in a promotional video for The Big Bertha Payday. “Now, even though you’re not the one hitting it, you at home have the chance to feel that same anxiety.”

By entering, you will join Phil in the grind over four-footers, the diabolical greenside shots for which Pinehurst is infamous and the unbearable major championship pressure. The better he plays, the more money you have a chance to win.

Although he missed cuts at The Masters and The Players Championship in 2014, Mickelson’s game sets up well for the Donald Ross designed Pinehurst No. 2, which requires imagination and supreme touch around the greens. In the 1999 U.S. Open at the same venue, Mickelson finished in a tie for second place, losing to a memorably gutsy performance from the late Payne Stewart.

In the 2005 U.S. Open at Pinehurst, Mickelson finished T33, earning him $35, 759. With a vested interest, participants will be hoping for a better showing in 2014’s rendition of the championship.

For the sake of one lucky fan, let’s hope Mickelson at least makes the cut. For everyone else, the contest is a great excuse to try out Callaway’s newest drivers and fairway woods.
