Phil Mickelson's PGA Championship victory prompted a massive leap in his odds to win the U.S. Open and The Open Championship.

The unexpected victory by the 50-year-old Mickelson in the second major of the season in South Carolina over the weekend prompted books to adjust futures bets on Mickelson for the next two majors.

Mickelson will turn 51 on June 16, one day before the U.S. Open opening round at Torrey Pines Golf Course in San Diego.
