I agree with all your surprises, especially Rory McKilroy's 63, and come back after his 80, Louis Oosthuizen's eagle and 16 under, and the flags staying in on Friday! : ). Was kinda surprised by the amount of ball-movement on the greens on Friday too...joey it was Jimenez who did that crazy wall-shot : )
I'll add these three:
Rickie Fowler's long putt for birdie on the 17th
Amateur Jin Jeong's excellent performance, finishing T14th,
John Daly's trousers (US - pants), though they shouldn't be a surprise anymore, lol!
There were many others, it's all a bit of a blur at the moment, I watched so much of the coverage!
