ST. ANDREWS, Scotland -- Around 200 million people worldwide watched on television as the final pairing teed off on Sunday. This is what happened in the moments before the two men walked into the frame: Louis Oosthuizen, the leader, checks his iPhone, hands it to caddie Zack Rasego, asks for it back, checks it again and, finally, lets it go. The next time he turns it on, it will be full of text messages and voice mails, words of congratulations or regret. A friend in the crowd makes eye contact with Rasego, and they hug.

"You've come a long way, hey?" the friend says.

Paul Casey, 4 shots back, hits a few final putts, then leans up against the green fence around the putting green, talking to someone. Someone calls out, "All the best, Paul."

Then it's time. The tee is clear. The kid with the score sign walks past. Blue arm-banded marshals follow him. The caddies pick up the clubs.

Game on.
