PGA Championship: No. 13 has been a monster and it might make the difference at Oak Hill

The 612-yard hole has not yielded an eagle this week, and it will not be reachable on Sunday.

The 13th hole at Oak Hill Country Club is a monster par 5, playing to 612 yards in the fourth round of the PGA Championship.

The hole has not yielded an eagle this week, and at that length and with a creek running through the middle of the fairway, it will not be reachable on Sunday.

The hole has been cut 7 yards from the front-middle portion of the green, which seems like an exposed location, but the flag is in a tricky spot.

The entire green complex tilts from back to front, but the hole is at the top of a thumbprint-style depression. Any ball that stops above the flag will leave a screamingly-fast putt, and shots that go left or right will leave a putt with a lot of break.

The make a birdie on Sunday, players will have to leave the ball below the hole and then putt up to it.
