He definitely delayed, he took a roundabout way to his ball, wasted more time bending over and looking at it right before it dropped. The sniff test is what would he have done if it was an inch from the cup, after agonizing that it didn't go in, he'd have walked straight up and tapped it in.
I agree with @chspeed that I wouldn't consider it an unreasonable delay since he's allotted 10 seconds and he probably only wasted another 5 seconds giving it time to drop. It's all a matter of when the clock started, if they reviewed it, I could see it going either way.
Maybe it's near the end of the 10 seconds at worst, but I mean c'mon...it's not like he's standing there staring at it with his hands on his hips. He's allowed to check whether it's at rest or might still drop, and that might require looking from a couple of different angles. Plus he had to get around the other line of putt, as has been mentioned.
I've said it before, but in a casual round you can have all the music you want as long as I can't hear it. If I can hear it at any time then it's too loud. I'm hearing impaired (I wear hearing aids) and I can usually hear music from the next fairway over even when they think that it's only loud enough for them to hear.
Only as loud as in your car? At times the music in my car could be heard 3 holes away when certain songs come on. Since that is about the only time I do listen to my music, I play it pretty loud when I'm driving alone. When something like Highway Star by Deep Purple comes on, I crank it up and rock, but I don't want to hear that on the golf course.
I don't get it anyway. I really don't understand why people can't disconnect for 4 hours. 4 hours people! You can listen in your car, listen when you work out, listen when you walk the dog... on and on ad infinitum. Why the hell can't you turn it off on the golf course? Learn to enjoy the music of nature. The rules don't allow you to listen to music during competition, so why is so necessary in casual rounds?
That reminded me of a comment I heard during yesterday's round on the webcast. I think it was Rory from 80 yards hit it like 8 feet left and they were talking about how bad that was... It's like they don't even bother looking at or knowing the actual stats.
