Jason Day drained a 35-foot birdie putt on his final hole on Friday to take a two-shot lead in the second round of the Arnold Palmer Invitational in Orlando, Fla.
One stroke ahead overnight, Day, an Australian who is ranked third in the world, was again superb on the greens at Bay Hill, needing just 27 putts on the way to a seven-under-par 65 and a 13-under aggregate of 131.
Henrik Stenson of Sweden was alone in second after firing a seven-birdie 66, with the former United States Open champion Justin Rose of England a stroke further back at 10 under, also after a 66.
