Four-time major champion Phil Mickelson and second-time major starter Billy Horschel remained tied for the lead after the second round of the US Open as Saturday challengers faded.
But world number one Tiger Woods, a 14-time major golf champion chasing the all-time record of 18 majors won by Jack Nicklaus, lurked only four strokes off the pace in a share of 13th with the third round looming Saturday afternoon.
