Thinking he might have a chance for a playoff, Jordan Spieth rolled in a 10-foot birdie on the 18th hole in regulation. He made an even bigger shot at Harbour Town’s signature hole in a playoff to win the RBC Heritage.

Spieth’s 56-foot shot from a greenside bunker stopped 7 inches away and he beat Patrick Cantlay with a tap-in par Sunday on the lighthouse hole for his 13th career PGA Tour title — and second straight on Easter Sunday.

Spieth, at 13 under after his 5-under 66, finished four groups ahead of Cantlay and waited out the stellar field that had several chances to tie or move in front. But all except Cantlay could not chase down Spieth, who stayed away from watching too much of the action once he finished.

“Every single putt looks like it’s going in,” Spieth said. “It was way more nerve-racking than actually playing.”

Spieth was certain he’d get passed by Cantlay, the FedEx Cup champion, past Open Championship winner Shane Lowry or third-round leader Harold Varner III. When all three parred the par-5 15th, the best chance for birdie on the back nine, Spieth felt his chances improve.

When Spieth finished, he was a stroke behind Lowry. But Lowry’s chip on the par-3 14th raced across the green and into the water, leading to double bogey. He finished a stroke back after a 69.

After Cantlay, who was tied for the lead after a birdie on the 17th, hit his approach on the green on his closing hole of regulation, Spieth headed out to loosen up, certain he’d be called back after Cantlay made the winning putt.

Instead, Cantlay slid it by right to set up the playoff.

In the playoff, Cantlay also hit into the front bunker, with his lie looking like a fried egg. He blasted 35 feet past the cup and missed the par putt.

Cantlay was 179 yards from the hole in the playoff and used a 9-iron as he did a short time earlier in regulation. This shot came up short of the green and in an awful position.

“Obviously, with it plugged like that, it’s darn near impossible to get it close,” Cantlay said.
