Aleksandar Vukic and Rei Sakamoto meet in the first round at US Open on Monday. Aleksandar Vukic is searching for form, having lost 2 in a row (6 of the last 10). Rei Sakamoto has won 5 of the last 10.

Neither the serve numbers nor the ratings separate these two by much, which is why our number stays close to even. A tiebreak or two would surprise nobody, with Vukic fractionally more likely to land the big points.
