Tiger seemed to think he stiffed it on #17, and really, catching the lip as he did meant that if he'd only gotten a few more feet out of it, he would've been right. Downwind out of the light rough, he again went for the perfect shot and in this case only barely missed. His line was certainly perfect if his goal was to hit it to tap-in range.
It wouldn't have taken much more from him on only a shot or two and we'd all be bowing down to his performance.
Looking at it with a bit more perspective, consider now that Tiger had two chances in the last two Masters to come from behind and get the job done on the back nine, and he narrowly missed both while battling an inconsistent putter in 2006 and now in 2007 some rather large swing problems. I remember short eagle putts on 13 and 15 last year, plus close birdie attempts on 12 and a few others coming in, and he wasn't able to capitalize on them to put the heat on Phil.
And the year before, he was also battling his swing and still hung on against Chris DiMarco.
For some reason he's not getting his game to peak in April, but he's still having chances every year. What happens once he finally gets his timing right again?
