As for Tiger, I watched about a half hour straight of coverage this morning on the golf channel of him on the range. Probably 40 swings, and something was clearly not right. Swing was flat, ball was coming off the club very funny, with little to no trajectory, and mostly going right. I've seen him on the range dozens of times, and I don't remember him moving so slowly (probably taking a full minute or so between each swing). Something was clearly wrong prior to the round. Won't stop everyone from claiming that he just quit because he was out of contention, but whatever, he's got nothing to prove to anyone.
And Palmer just fucks up an easy wedge shot on 18. Probably looking at par at best on the par 5. Unbelievable.
