Fred Couples said he needed to be close to perfect to post a low round on Sunday. So far, he's been close to flawless.
Couples nearly eagled the par-5 second hole. His second shot, which landed on the opposite side of the green, benefitted from a long, slow roll toward the pin. Couples barely missed the eagle putt, but converted on the birdie try.
On the following hole, Couples chipped from the edge of the green, holing out for his second straight birdie.
Couples, who is vying to become the oldest Masters champion at 50, now stands two shots behind co-leaders Phil Mickelson and Lee Westwood .
