US Open Daily Graph - Djokovic vs Wawrinka

Today's graph comes from Novak Djokovic's "comeback" victory over Stanislas Wawrinka in the US Open Semi-Finals. For evenly matched players, the probability graph below would have had a lot more movement to it. But this was not an evenly matched game as Djokovic had an initial win probability of 82%. Even in his deepest hole (dropped the first set and down 2-4 in the second), Novak's win probability only got as low as 40.2%. This is consistent with the in-play odds offered at William Hill sportsbook, where Djokovic was never worse than 3/2 to win the match (~40% probability).
