DUBLIN, Ohio — Collin Morikawa never looked like a winner at the Workday Charity Open until he tapped in for par on the third playoff hole, capping off a wild finish Sunday at Muirfield Village.

Morikawa trailed Justin Thomas by three shots with three holes to play and managed to get into a playoff with a 6-under 66. Then, after watching Thomas hole a 50-foot birdie putt on the first extra hole, he had to make a 25-footer just to stay alive. He could only watch as Thomas had a 10-footer to win on the 18th on the second playoff hole.

It finally ended on No. 10 when Thomas had to lay up from behind a tree and made bogey, and Morikawa took two putts from just inside 10 feet for his second career victory, and first against a strong PGA Tour field.

“It was crazy,” Morikawa said.

It was a shocker for Thomas, too. He lost a two-shot lead at the start in three holes. He ran off four straight birdies and had 10 consecutive one-putts to build a three-shot lead through 15 holes.

Thomas didn’t do anything terribly wrong — a tee shot in the thick collar on the par-3 16th that led to bogey, a 12-foot birdie attempt on the 17th that narrowly missed and a tee shot that found a bunker on the 18th and led to another bogey and a 69. They finished at 19-under 269.
