Patrick Cantlay defeated Collin Morikawa in a play-off to win the Memorial Tournament on Sunday.

Cantlay earned his second Memorial title, having also won the tournament in 2019, after Morikawa was unable to match his par putt on the first play-off hole.

A sudden-death shoot-out was needed at Muirfield Village Golf Club after Cantlay and fellow American Morikawa finished 13 under through 72 holes following final-round 71s.

It became a showdown between Cantlay and Morikawa on the final day after runaway leader Jon Rahm was forced to withdraw following a positive coronavirus test.

Defending champion Rahm was six shots clear of Cantlay and Morikawa in the third round before the duo were thrust to the top of the leaderboard.

"It's such a weird situation and so unfortunate because, me included, everyone knows it would be a totally different day today had that [Rahm's withdrawal] not happened," Cantlay said after his fourth PGA Tour triumph.

"There's nothing I can do about it and I just tried to work as hard as I could to reset and really get focused.

"I started off a bit shaky today but I really hit a lot of good shots coming in and it felt the same as when I won a couple of years ago. I felt calm and collected and it worked out."

Scottie Scheffler (70) finished two shots behind Cantlay and Morikawa, while Branden Grace (71) was a stroke further back as Patrick Reed and his three-under-par 69 earned him outright fifth at eight under.

Reigning U.S. Open champion Bryson DeChambeau (71), four-time major winner Rory McIlroy (72) and former world number one Jordan Spieth (73) ended the event in a share of 18th position at one under.
