Djokovic played with marbles while waiting for 6-hr SF to end
Ex-world number one Novak Djokovic played with marbles while waiting for the outcome of the first Wimbledon semifinal between John Isner and Kevin Anderson, which turned out to be tennis' third-longest singles match (6 hours 36 minutes). Djokovic was waiting to play Rafael Nadal on centre court. Wimbledon's time constraints led to the Djokovic-Nadal semifinal being suspended after three sets.
