I didn't watch all days, but the day I did, the Mickelson-Harrington-Perry trio didn't seem to have too much trouble w/ up-and-downs after all used driver (admittedly, three pretty long and good players...Phil and Paddy had birdies, while Perry missed a somewhat makeable birdie putt). I clearly got the impression from the announcers, who seemed really taken by the hole, that the ability to get up and down depended on pin position. The day I watched, I believe the pin was left-center.
