The 2018 PGA Championship is being decided Sunday, and the top of the leaderboard is absolutely stacked. In other words, no matter what else you're doing to cap off your week, be sure to tune in all day long at Bellerive Country Club.

Brooks Koepka held the 54-hole lead, but some of the top golfers in the world are right on his heels Sunday. Tiger Woods opened his Round 4 by going out in 32, posting four birdies and a bogey despite hitting zero fairways in his front nine. He sits two back at the turn, while Justin Thomas is one behind Koepka but multiple holes ahead of both men.

With coverage continuing live on CBS, every one of Tiger Woods' shots in Round 4 will be available both on your TV and streaming online. There have been low scores all week long, and there's no reason to expect anything different on Sunday in St. Louis.

Keep on scrolling for Sunday's schedule and every way you can catch the action live.
