Jason Day takes four shot lead at Sawgrass

World number one Jason Day overcame conditions described as "nasty" and "borderline unfair" to maintain his four-shot lead heading into the final round of the Players Championship.

Day, who had established a 36-hole scoring record when the delayed second round was completed at Sawgrass on Saturday, four-putted the sixth hole in the third round and also double-bogeyed the eighth to see his lead cut to a single shot.
