A look at the key hole in the second round of the British Open:
STROKE AVERAGE: 3.77
KEY FACT: Danny Willett made a birdie on his final hole to take the clubhouse lead on a day when other leaders didn't finish. The 18th was also the scene of not one, but two, goodbyes to golfing figures with Nick Faldo going across the famous Swilcan Bridge one last time and Tom Watson doing the same as darkness enveloped the Old Course. Faldo won three British Opens, and Watson won five.
