When he reached the end of his practice round, Phil Mickelson could only chuckle. "You think anyone has ever grinded this hard on a Monday?" he said. It was only a practice round at the British Open, and a high-stakes game with Dustin Johnson and Nick Watney. But it was high entertainment at the end, even for Mickelson. The threesome had side bet on stroke play, with the loser paying the winner (whoever finished second was off the hook). Johnson roared out to a big lead, turning in 3 under, until the back nine tripped him up. Mickelson surged to a big lead until back-to-back bogeys, then a tee shot so far left on the 17th he thought he wouldn't find it. http://sports.espn.go.com/golf/britishopen10/news/story?id=5374269
