Our calls: Bencic over Ostapenko, Bergs over Samuel, Nakashima over Medjedovic, Siniakova over Stearns, Droguet over Altmaier, Shnaider over Putintseva, and 22 more.
The boldest call on the card: Collignon over Basavareddy — the market disagrees with us there.
Not gradedThis match ended in a retirement, advancing Belinda Bencic. It is excluded from our graded record — no pick is counted as right or wrong.

Win probability: 60% Bencic · Market: -132 · We call it in 2 sets (63%) · single likeliest score 2-0 (39%)
A spot in the next round is at stake on Tuesday, when Belinda Bencic goes up against Jelena Ostapenko in the Ningbo round of 32. Belinda Bencic limps in on a 2-match losing skid, just 6 wins in 10. Jelena Ostapenko has won 6 of the last 10.
Belinda Bencic simply rates much higher on hard, and our number follows from it. Little separates them; Bencic gets the nod on the finest of margins.

Pick: Bergs
Win probability: 61% Bergs · Market: -202 · We call it in 2 sets (61%) · single likeliest score 2-0 (39%)

Bergs's 72.5% behind the first serve (against 68% for Samuel) means break chances should be scarce in one direction. The edge belongs to Bergs — real, but not the kind you take for granted at this level.
