Day leads Masters, but Woods and Guan still in contention
(CNN) -- Australian golfer Jason Day leads the pack after two rounds of the Masters golf tournament, though a host of players -- including No. 1 ranked player Tiger Woods and Chinese teen phenom Tianlang Guan -- remain in contention for the prestigious green jacket.
Day surged to the top of the leaderboard by shooting 4-under-par on Friday to finish 6-under after two rounds. Fred Couples and Marc Leishman sit one stroke behind him, at 5-under-par after two rounds.
Tiger Woods was among the leaders much of the day but faltered late -- done in, in part, by bad luck after his ball hit the flagstick on the 15th hole and careened into the water. He trails Day by three strokes.
