"It is also refreshing that they are encouraging "ready golf" in strokeplay, so that a player primed to play does not have to wait for someone less prepared and further from the hole.
"Course set-up is another key factor, as we witnessed at Sawgrass last Saturday when lightening quick greens led to rounds ridiculously stretching beyond five and a half hours. Fast greens seemed to lead to slow play at the Players Championship and the R&A plan to study further the significance of this correlation."
