The 60-year-old German, a three-time victor of the Houston-area event, is seeking his first victory of 2018 after seven wins last year.
"I had no idea where the ball was going today; especially off the tee", Day said afterwards.
After starting the day seven behind leader Jason Day, McIlroy was unable to mount a final-day charge as he mixed three birdies with as many bogeys. He stretched out both arms in mock celebration after his 2-over 73. Lucas Glover in 2011 is the only player to post all four rounds in the 60s at Quail Hollow since the tournament began in 2003. He took off his shoes and stood in the water to hit his approach then slipped them back on for the walk to the final green and closed with a par. I've had ample time to make the adjustment, and I just haven't.
"This is probably the best win of my career, simply because I didn't have my A-game out there today". Woods shot 73 to finish at 2-over 144. For the sake of context, tournament victor Day finished just behind Woods in strokes gained tee to green (but he putted 70 spots better). He rolled up his trousers, played the ball above his feet on the embankment and eventually made par.
Malnati made two straight birdies and finished with a par that felt like a birdie.
Tiger Woods goes off at 11:05. His chip checked up about 8 feet short of the cup and he missed that. On the back nine, he started with an eagle on hole number 10 and would birdie #14 and #15. "If I just putt normal, I'm right there". For that, he needed to replicate his stunning final round of 2010 - when a closing 62 saw him leapfrog through the field to claim the title - but, this time, the Northern Irishman was unable to reproduce any of that drama and ultimately was confined to the role of bit player. I'll still be grinding, working on my swing and making sure that's solid, driving the ball correctly because that golf course does demand everything.

Then he stood on the par-3 17th, where Justin Thomas shut down the 2017 PGA, and he almost dunked an ace.
There were no back issues to speak of this week at Quail Hollow, just a frustrating inability to find any comfort on the greens and just enough wayward shots that he made just 10 birdies for the week.
Watney's last tournament win overall came later in 2012, at the CIMB Classic on the Asian Tour. And he was still out of golf recovering from back surgery last summer when Quail Hollow hosted the PGA Championship.
This is a new course to him.
The Australian birdied the second hole and then exchanged two bogeys at the fifth and sixth with consecutive birdies at seven and eight.
He walked off the seventh green holding his putter, one hand on the grip, the other on the head, as if he wanted to break it in half.
"I'm close, " said Woods. The chances I did have, I missed them all. "I just kept on saying to myself, 'Forget about it and keep pushing'".
