LAKE FOREST, Ill. (AP) -- A long day for Jason Day ended even better than it began, thanks to an eagle putt at the 18th that extended his lead to five shots at the BMW Championship.
He shot an 8-under 63 to set a 36-hole tournament record at 18 under. Day's closest pursuers were rookie Daniel Berger and Brendon Todd. Todd finished off Friday's round of 63 by holing out an 81-yard wedge shot at No. 18. Berger made his move with four birdies in a five-hole stretch en route to a 30 on the front nine.
