SAN FRANCISCO: This was the 15th time Phil Mickelson has played in the Presidents Cup or the Ryder Cup, and the first time he came alone. His wife, Amy, is recovering from breast cancer and stayed home in San Diego.

Or so he thought.

Mickelson had no idea that when he returned to his hotel room on Saturday night, his wife was hiding in the bathroom. "It was an incredible surprise," Mickelson said. "I didn't think she was coming up and she actually hid in the bathroom when I walked in the room. I didn't know she was there and she scared me pretty good. It was an awesome surprise, though."
