Schwartzel faces a left-edge 12-footer to take sole possession of the lead for the first time. He knows what's at stake.
Schwartzel: You can't miss the leader boards at Augusta. They're so big. So if a guy at Augusta says he never sees a leader board, he's lying. I believe everyone always knows what's going on.
Schwartzel pours in his putt to reach 13 under. Walking up the 18th fairway, Scott hears the cheers and knows he is now one behind.
Scott: I was up the right side of the fairway. I couldn't hit a straight shot to the pin; I had to move it left to right slightly because the trees were tight. I cut it a bit too much. It wasn't a bad shot, I simply didn't get any of the funnel toward the hole.
His ball stops 30 feet from the flag. Day feeds his second shot off the green's slope to within eight feet. As they walk to the green, Scott gives his longtime friend a low five.
Day: We had a blast out there. We were talking, having fun. It was a lot easier, I'll tell you that much, to play with Adam.
Schwartzel arrives at the 18th tee as Scott and Day are studying their birdie putts. He must decide how aggressively to play the final hole.
Schwartzel: Whenever you're standing on the 18th tee with a one-shot lead at Augusta, it's not easy. That little tunnel gets very narrow. The whole week I hit three-woods to take the bunkers out of play, and I felt that I needed to hit a driver [this time]. I had been hitting my driver well, and I decided I'm going to lash it. I hit it way up there.
Scott is the first to putt.
Scott: I knew I had to make it. That's why I kind of gave my putt a good run. It was never on a good line, but the last thing you do in that position is leave it short. I thought, I may not ever be in this position again.
