"It goes to a lot of, one, how much further the golf ball is going and how much better the equipment and the players have become."

A common sense answer from Tiger on the low rounds of late:

Q. Assuming you've been watching the last couple weeks, does the threshold at 60 still exist or has that wall been torn down and destroyed? How much of that is between the ears? I think you've shot 61 here, so you must have even sniffed it that day.

TIGER WOODS: Well, I think it goes to a lot of, one, how much further the golf ball is going and how much better the equipment and the players have become.

You know, you're getting guys -- and it also depends on the venue, too. Not a lot of 59s and 60s have been shot on par-72s. They've been more 71s or 70s. Granted, they're still extremely low rounds, but you know, it's a little different deal getting to 10-under than it is to 13. It's a big, big difference.
