Phil Mickelson in a league of his own at Pebble Beach Pro-Am

Phil Mickelson closed in on his fifth victory in the tournament as he shot a six-under 66 to take a two-shot lead in the AT&T Pebble Beach Pro-Am.

It is the first time the left-hander has held a 54-hole lead on the PGA tour since the 2012 US Open at Merion.
