Record-setting Day leads by four at Players Championship

World number one Jason Day of Australia completed a 36-hole course record effort Saturday to seize a four-stroke lead entering the third round of the US PGA Players Championship. Another Australian, Greg Norman, had established the 36-hole Players record of 130 in 1994. Day's four-shot halfway lead over Ireland's Shane Lowry was also a new mark for the event, one shot lower than the old record margin set by Norman in 1994 and American Lanny Wadkins five years earlier.
