Phil Mickelson's 63 couldn't have come at a better time and while it'll be fun to see what he does Sunday, he's vaulted himself back onto the Masters favorites list after a mediocre start to the year. But it's the LPGA's first major of the year that has the potential for a fantastic finish with World No. 1 Yani Tseng taking the lead over Stacy Lewis, with Morgan Pressel and Michelle Wie lurking just enough that things could get interesting if someone goes low.
