Phil Mickelson extended his lead at the 2013 Waste Management Phoenix Open in Saturday's third round, finishing in a flurry of four straight birdies to take a six-stroke lead into Sunday's final round at TPC Scottsdale in Scottsdale, Ariz.
Mickelson, who shot a 60 on Thursday and lipped out a putt to finish at 59, shot a 7-under 64 on Saturday. His three-day total of 189 -- 60 on Thursday, 65 on Friday, 64 on Saturday -- tied the event's record.
Rather than tracking the rest of the field, Mickelson is closer to tracking the overall scoring record for the event. The Phoenix Open has been played at TPC Scottsdale since 1987, and the current scoring record is a 28-under 256, which Mark Calcavecchia scored in 2001. Mickelson would need a 4-under 67 to tie the record Sunday.
Brandt Snedeker shot a 6-under 65 in his third round Saturday, and he's alone in second place six shots behind Mickelson. Two strokes behind Snedeker are Padraig Harrington and Ryan Moore at 16-under. Harrington's 8-under round of 63 on Saturday was the lowest on the course.
