Woods didn't find another birdie until the 17th, where he drained a putt of nearly 45 feet to close within one stroke of Casey's clubhouse lead and send his massive gallery into a frenzy.
The former world number one and his massive following went dormant after an opening birdie to briefly share the lead.
Woods did just that, captivating the audience with a 44-foot putt on the 17th hole on the tournament's last day.
That was his best finish since he tied for second at that Barclays tournament, right about the time his back started to give out.
Who was playing downwind of Woods, last out of the clubhouse on Sunday. He has been a factor on Sunday the last two tournaments, and a gallery that stood 10-deep around just about every green could sense it.
Asked how he felt being in the mix for a tournament once again, Woods responded: 'It felt very comfortable, I remember it and my game is sharp, it was a good day. "I didn't feel that sharp with my iron game".
"It was one of those days where I kept getting the half club, and just couldn't quite get the full club".
Searching for his first PGA win since 2013, Woods was the centre of attention all Sunday, in just his fourth official event back after undergoing spinal fusion surgery.
Casey had four birdies and a bogey on his front nine, then seized control with three birdies on the trot at 11, 12 and 13 that moved him to 10-under. That was his last birdie until he revved up the raucous crowd with his long birdie on the 17th, giving him his best chance to win since his back problems began not long after his most recent victory, the Bridgestone Invitational in August 2013.
At that time, Reed was on his way to three-putting the 18th green from 45 feet to fall back to 9 under. This is a player who's been prepared for this moment for years - even if he had Tiger Woods chasing him down. "A couple putts here and there and it could have been a different story". Snedeker is streaky with his putter, but looks to be in form this week.
The 42-year-old finished tied for 23rd at Torrey Pines, then missed the cut at Riviera in Los Angeles before a 12th-placed finish at the Honda Classic two weeks ago.
It was Englishman Paul Casey, not Tiger Woods, who ended his long title drought at the Innisbrook Resort in Florida on Sunday.
Reed opened his round with a 60-foot eagle putt from the collar of the green at the first.
As the defending champion and fellow Canadian golfer who has lived through near misses, Adam Hadwin sees good times ahead for his compatriot Corey Conners.
"It was a very hard week, tough conditions on a tough golf course, very demanding, and I thought I held up really well". He hit a tree with his second shot on the first hole and bogeyed it, bogeyed No. 3 as well and ultimately finished with a 77, a tough but valuable learning experience. To be specific, in that span, he won five times on the European Tour.
