Adrian Mannarino and Learner Tien meet in the round of 32 at Washington on Tuesday. Learner Tien has won 7 of the last 10. Adrian Mannarino has won 5 of the last 10.
The two have never played — a first meeting always adds a layer of uncertainty the numbers can't fully capture.
Learner Tien simply rates much higher on hard, and our number follows from it. The edge belongs to Tien — real, but not the kind you take for granted at this level.
