US Open Daily Graph - Hewitt vs Del Potro

Earlier this week, I posted my first attempt at a tennis win probability graph, using Victoria Duval's come from behind upset over Samantha Stosur as an example. I am going to try to make this a daily feature for the remainder of the US Open. Each day, I will pick a particularly noteworthy match and publish its win probability graph. As I don't follow tennis too closely, I am open to suggestions as to which match to feature.

For today's post, I am using Leyton Hewitt's upset victory over Juan Martin Del Potro. As with my Duval graph, I am calibrating the inputs to the model such that the initial probability matches the betting consensus (Hewitt with a 12.8% win probability). See the table at the bottom of the graph for the assumed serve and return point probabilities.
