Jon Rahm leads the 2020 Memorial Tournament entering Sunday's final round at 12 under, four shots up on the field, and he doesn't have a lot of company at the top. Rahm entered Round 4 with four shots up on Tony Finau and Ryan Palmer; only six golfers are within seven of Rahm's lead as he looks to pick up a huge win not only for his career but this season.

Muirfield Village is playing like a major championship venue, which is phenomenal, and it looked the same as Sunday's final round got underway as scores continue to rise over par on a firm, baked-out golf course that rewards great shots and punishes bad ones. Will someone step up, go low and make a run on Rahm down the stretch? No one has done that just yet, though Patrick Reed did start hot on Sunday.

If Rahm wins, he'll go to No. 1 in the Official World Golf Rankings, but you know it won't be that easy coming home for him as he takes aim for the biggest event since the PGA Tour restarted just over a month ago. Sunday's action has already started fast and furious, but keep on reading for how you can watch the event wrap up in the afternoon.

All times Eastern; streaming start times approximated.
