Tuesday's Bloomfield Hills round of 32 pits Alex Michelsen against Arthur Gea on hard. Alex Michelsen comes in at 7 wins from the last ten. Arthur Gea comes in at 7 wins from the last ten.

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. Little separates them; Michelsen gets the nod on the finest of margins.
