Riccardo, thanks for that interactive from the NY Times. They had a similar item, which I can no longer locate, showing how Tiger Woods put his approach on 15 - I think in 2002, but possibly 2009 - close to the pin (on the upper right), but then it rolled all the way down to the bottom of the green.
Note that according to the Times, the upper right is the only place flat enough to put the pin, but on WGT it is usually on the lower left. (And in a video tour of the course on the NY Times, the pin appears to be on the upper left - that would be interesting.)
