A spot in the next round is at stake on Tuesday, when Maria Sakkari goes up against Robin Montgomery in the US Open first round. Maria Sakkari has won 4 of the last 10. Robin Montgomery comes in at 6 wins from the last ten.

Maria Sakkari simply rates much higher on hard, and our number follows from it. A tiebreak or two would surprise nobody, with Sakkari fractionally more likely to land the big points.
