Notable Notes: Larry Nelson fought past Tom Watson to win the trophy. Nelson trailed Watson by one entering the final round, but Watson opened a 3-shot lead after nine holes of Round 4. However, from that point the momentum reversed, with Nelson making some birdies and Watson some bogeys. Watson had a putt on the final green to force a playoff, but missed.
