Jason Dufner and Fred Couples are the toast of the fairway on Friday night. The two underdogs will have to work hard to maintain their advantage in the third round of the 2012 Masters on Saturday.

Five other golfers are one stroke behind Couples and Dufner, including a favorite heading into the event, Rory McIlroy.

You can watch the action unfold online or on the television, or both if you want to get really crazy with it.
