It wasn't even close in the end; not because Rickie didn't make it interesting with a couple of balls in the water. It wasn't close in the end because none of the also-rans could mount a charge in the difficult conditions, with swirling winds, sometimes upwards of twenty miles per hour. Only Jonny Vegas was able to go low early with a terrific 64. But he was too far back to challenge, eventually finishing tied for fourth.
And ultimately, as it often is, it was the "power of the putter" that kept any wolves at bay for Rickie. When things were starting to look bad, and his ballstriking was shaky, Rickie drained a couple of long birdie putts and was able to come home with plenty of shots to spare. You can get away with some iffy ballstriking if you can putt. That putter covers a multitude of sins. Three of these and one of those still makes four, as the great Walter Hagen said.
It's worth noting that Rickie never missed a putt inside seven feet for four rounds. That, my friends, is rolling your rock. Well done, Rickie.
