The US Open title is on the line on Sunday, when Alexander Zverev meets Ben Shelton. Alexander Zverev is rolling — 6 straight wins, 8 of 10 in recent play. Ben Shelton is rolling — 5 straight wins, 9 of 10 in recent play.

Neither the serve numbers nor the ratings separate these two by much, which is why our number stays close to even. Little separates them; Zverev gets the nod on the finest of margins.
