Though the conditions were benign, they still did not lead to many low scores on the devilish Pete Dye-designed layout. Thomas, whose closing 36-hole score of 12 under par was a tournament record, vaulted to the top of the leaderboard with birdies on the ninth, 10th and 12th holes — along with his eagle on the par-5 11th hole.With DeChambeau and Westwood, the top two finishers at last week’s Arnold Palmer Invitational, trailing but not totally out of the picture, Thomas came to the par-5 16th hole needing a daring strike. For his second shot from the fairway, Thomas hit a gutsy 5-wood that curled onto the 16th green from 228 yards. It was Thomas’s first attempt at an eagle putt in his career on the golf course’s 16th hole, which he did not make from 46 feet. But he tapped the ball in for a crucial, timely birdie.“I was proud that I took some chances that paid off,” Thomas said.A second successive second-place finish did not leave Westwood, who will turn 48 in April, dejected. He appeared at a news conference with a wide smile.“I’m just having so much fun — everybody keeps telling me how old I am,” Westwood said, laughing.
