3 matches are on Friday's card at Sao Paulo, and we have a pick for every one of them. The headline act: Alina Charaeva against Anna Blinkova in the quarterfinal. Our calls: Blinkova over Charaeva, Kostovic over Quevedo, Podoroska over Lamens.

Kaitlin Quevedo vs. Teodora Kostovic

✗ Pick wrongMissed it. We had Teodora Kostovic at 52%, but Kaitlin Quevedo won 6-3 6-4.

Pick: Kostovic

Win probability: 52% Kostovic · Market: +129 · Sets: 3 (43%) · most likely score 2-0 (30%)

A spot in the next round is at stake on Friday, when Kaitlin Quevedo goes up against Teodora Kostovic in the Sao Paulo quarterfinal. Teodora Kostovic has won 4 of the last 10. Kaitlin Quevedo comes in at 4 wins from the last ten.

Kostovic's 63.8% behind the first serve (against 60.7% for Quevedo) means break chances should be scarce in one direction. Quevedo comes in off a compressed schedule. This one is close to a coin flip, and the lean toward Kostovic is exactly that — a lean.

Alina Charaeva vs. Anna Blinkova

✓ Pick rightWe got this one right. Anna Blinkova was our 55% pick, and won 6-4 7-5.

Pick: Blinkova

Win probability: 55% Blinkova · Market: -143 · Sets: 2 (58%) · most likely score 2-0 (33%)

Anna Blinkova is clearly higher-rated on hard — our number puts Blinkova around 55%. Little separates them; Blinkova gets the nod on the finest of margins.

Nadia Podoroska vs. Suzan Lamens

✓ Pick rightWe got this one right. Nadia Podoroska was our 59% pick, and won 7-6 3-6 6-3.

Pick: Podoroska

Win probability: 59% Podoroska · Market: -108 · Sets: 2 (62%) · most likely score 2-0 (37%)
