Some of golf's biggest names paid tribute to Rory McIlroy after his fantastic comeback win at the Deutsche Bank Championship in Boston yesterday.
McIlroy was four over through the first three holes of the championship, but he roared back into contention at the weekend before sealing victory with a six under par final round of 65.
His putting, which has so often let him down when he needed it most, was on fire as he rolled in several key putts on his way to victory, with his switch to a new Scotty Cameron putter undoubtedly a positive change.
World No.1 Jason Day, who finished seven shots behind McIlroy in a tie for 15th, pointed out how important that was for the Northern Irishman's confidence.
"A few putts go your way, you get a little bit of confidence, start rolling them in and you start feeling good about yourself," Day said after his final round of 67.
"Over the last few days he's obviously been playing pretty well."
Jordan Spieth, who has dropped below McIlroy in the world rankings to fourth, also spoke of how impressed he was by McIlroy's determination to improve.
"He's been on the practice green every time I've been there," Spieth said.
"I feel like I work hard on my putting, but he's worked as hard as anybody in the past two weeks on his putting."
Day's fellow Australian Adam Scott also praised McIlroy for his resilience after the new World No.3 received a lot of criticism earlier this season for not performing as well as his major rivals.
"He's remarkable because he's a bit Teflon-coated," Scott said.
"He gets criticised a lot, everything's analysed, but he's very patient I think with it all.
"To me it looks like he hasn't got so frustrated this year, he's just kept doing his thing."
But runner-up Paul Casey, who was the overnight leader and had led McIlroy by six shots heading into the final round, summed it up best with his straightforward, one-word response to how he felt his opponent had played in yesterday's final round.
He said: "Brilliant."
