Matt Fitzpatrick believes learning to be patient has been his secret to success.

The reigning U.S. Open champion went into the final round of the RBC Heritage on Sunday with the outright lead after a spectacular career-best round of 63 on Saturday, but had to survive a three-hole playoff against Jordan Spieth before securing victory.

Fitzpatrick fell two shots off the lead at one point, before recovering to force a playoff against Spieth.

"The big thing for me, that I feel like I've learnt when I play well, is just having patience. Just letting it happen and just giving myself time," Fitzpatrick said.

"I just felt as long as I was within two shots going into the back nine, I was easily in with a shout."

The Englishman moved up to a career-high number eight in the world after his win at the Harbour Town course at Hilton Head, just his second PGA Tour win after the U.S. Open.

"Before winning the U.S. Open, before last year really, I probably got overworked over majors," he said. "I was that desperate to try and win one, just changing things, trying a bit harder.

"I probably made myself tired from that, and then you come to this week and you just feel tired from the week before.

"I think sometimes it can be tough, particularly if you really had a grind, if you had a good result. I think it can be difficult to get yourself up for it."

This shot earned @MattFitz94 the trophy and an additional $1,420,000.
