And then he hit his drive on the par-4 13th.
Tringale blew his ball right into the trees, played his second off wood chips, missed the green, and failed to get up-and-down. Rather than take advantage of a wide fairway and TPC Louisiana's fifth-easiest hole, Tringale walked away with a bogey that zapped all his momentum.
He made par on his next four holes and left himself needing an eagle-3 on the par-5 18th to force a playoff with eventual winner Justin Rose.
"You don’t have that many chances to win out here," Tringale said. "To give myself a realistic shot at a three, I felt I needed to at least get it up around the green."
Which he did. Tringale played his second shot from 250 yards just short of the green, but his chip for eagle and a playoff came up 17 inches short.
He tapped in for birdie and finished in second place for the second time in his career, following his runner-up at last year's Barclays. Despite the near-miss, Tringale didn't sound discouraged.
"It was a great week for me," he said. "I missed the cut last week, went home, re-grouped, worked on a few things just to tighten up my game, came and had a great week.
"To just be one back after it’s all said and done, obviously it’s disappointing … but it’s a great week."
