Phil Mickelson had a seemingly gargantuan lead in the Northern Trust Open at four strokes but it has since evaporated and now he’s in a tie for third at 13-under. Mickelson eagled the first hole, then unraveled from there. He has yet to make a birdie today. Yesterday, he made six birdies on the back nine and seven total. Steve Stricker is in the lead at 15-under, and Rory Sabbatini is in second at 14-under. Mickelson and Fred Couples are tied for third at 13-under, two shots behind Stricker. Mickelson was at 18-under after eagling the first and has played Riviera at 5-over par since then.
