Congrats to Bob and Mike Bryan, who cemented the year-end #1 ranking in men's doubles by winning their last match of the season today. This was an improbable result, as the twins entered the ATP Finals event with a huge deficit in ranking points and then promptly lost the first of their round-robin matches. The pair won four in a row, though, and threaded the needle by assembling just what they needed to win the tournament and recapture the top ranking.
