The 103rd PGA Championship will take place Thursday-Sunday from Kiawah Island Golf Resort in South Carolina.
Will 2020 PGA Championship winner Colin Morikawa make it two in a row? Will Brooks Koepka win another major this week?
Our golf handicapper Brady Kannon is here to recap every round and give his best bets for the next day.
Round 4 best bets
Kannon: Phil Mickelson made his way to the tee box on the 12th hole at the Ocean Course at Kiawah on Saturday, 5-under par on his round and 10-under par for the championship. He held a 4-shot lead over his playing partner, Louis Oosthuizen and was 5-shots ahead of Brooks Koepka.
When life looks like Easy Street, there is danger at your door.
Mickelson then played the next two holes in 3-over par and we had ourselves a whole new golf tournament. Oosthuizen, who had played so flawlessly the first two days, lost over three strokes to the field putting on Saturday and hit less than 36% of fairways off the tee. The regression we expected for Phil happened, too, as he hit only half of the fairways and also lost strokes on the greens.
Heading into Championship Sunday, Mickelson is your leader at 7-under par, followed by Koepka at 6-under. They will be the final pairing tomorrow. Oosthuizen is two back at 5-under par. Another six players trail by five shots or less, including Bryson DeChambeau at 2-under par for the championship.
Tomorrow comes trouble, tomorrow comes pain. Now don't think too hard, baby, 'cause you know what I'm saying.
Mickelson, at just a few weeks shy of 51 years old, is the oldest player to ever be the 54-hole leader of a PGA Championship. He's the oldest player to own the 54-hole lead at any major since Tom Watson (59) led the British Open in 2009. Watson ended up losing to Stewart Cink in a playoff that year at Turnberry.
