Tuesday's Bloomfield Hills round of 32 pits Coleman Wong against Steve Johnson on hard. Steve Johnson comes in at 5 wins from the last ten. Coleman Wong is searching for form, having lost 5 in a row (2 of the last 10).
The two have never played — a first meeting always adds a layer of uncertainty the numbers can't fully capture.
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 Johnson fractionally more likely to land the big points.
