BOSTON • By relinquishing his European Tour card to focus on the US circuit, Paul Casey gave up any chance of making this month's Ryder Cup team.
But the British golfer will feel that decision has been vindicated if he wins the Deutsche Bank Championship.
The 39-year-old made his home in the US several years ago and lives in Arizona with his second wife Pollyanna and young son Lex.
He gave up his European card for last year, having been a member since 2001, as he felt he was spreading himself too thin trying to play both tours.
A 13-time winner on the European Tour, he played in three Ryder Cups but was controversially left off the 2010 team despite being one of the world's top-ranked players at the time.
On Sunday, he put himself in pole position for just his second PGA Tour victory in 194 starts when he eagled the final hole to take a three-shot lead in the third round at TPC Boston in Norton.
The Englishman's approach shot from 235 yards at the par five landed just in front of the green and rolled up to inside a foot of the hole.
He tapped in for a third consecutive 66 and a 198 total, with American Brian Harmon (68) in second place on 201.
"It was more of the same great ball-striking," Casey told Golf Channel. "Attitude was great as well.
"I'm loving that I'm in the lead. I've had a few events out here and only got one win, so I'd love to double that tally. If it doesn't happen tomorrow, I'm pretty confident it will happen relatively soon."
Harmon, with one Tour victory, moved into second place with a tidy four-birdie performance.
Americans Jimmy Walker, Kevin Chappell and Smylie Kaufman are four strokes behind Casey in the second of the PGA Tour's four FedEx Cup play-off events.
Halfway leader Chappell plodded to a 71 which included a double bogey at the par-four 12th, where he took four strokes to hole out from just off the green.
PGA Championship winner Walker (70) had two bogeys in the first three holes, while Kaufman (68) also started slowly with a bogey at the par-five second.
World No. 5 Rory McIlroy vaulted into the picture with a 66 and is tied for seventh with South Africa's Louis Oosthuizen, who carded a 64, on 204.
