4 matches are on Thursday's card at Sao Paulo, and we have a pick for every one of them. The headline act: Alina Charaeva against Elina Avanesyan in the round of 16. Our calls: Avanesyan over Charaeva, Lys over Podoroska, Badosa over Ortenzi, Sierra over Lamens.

Solana Sierra vs. Suzan Lamens

✗ Pick wrongMissed it. We had Solana Sierra at 64%, but Suzan Lamens won 6-3 6-2.

Pick: Sierra

Win probability: 64% Sierra · Market: -123 · Sets: 2 (62%) · most likely score 2-0 (40%)

A spot in the next round is at stake on Thursday, when Solana Sierra goes up against Suzan Lamens in the Sao Paulo round of 16. Solana Sierra limps in on a 3-match losing skid, just 4 wins in 10. Suzan Lamens limps in on a 4-match losing skid, just 4 wins in 10.

On paper it's close: comparable ratings, comparable serve numbers, small margins everywhere. The edge belongs to Sierra — real, but not the kind you take for granted at this level.

Eva Lys vs. Nadia Podoroska

✗ Pick wrongA miss: Eva Lys at 62% lost to Nadia Podoroska (7-5 6-2).

Pick: Lys

Win probability: 62% Lys · Market: -163 · Sets: 2 (64%) · most likely score 2-0 (41%)

Eva Lys and Nadia Podoroska meet in the round of 16 at Sao Paulo on Thursday. Eva Lys has won 4 of the last 10. Nadia Podoroska has won 4 of the last 10.

Neither the serve numbers nor the ratings separate these two by much, which is why our number stays close to even. The edge belongs to Lys — real, but not the kind you take for granted at this level.

Alina Charaeva vs. Elina Avanesyan

✗ Pick wrongA miss: Elina Avanesyan at 54% lost to Alina Charaeva (6-2 6-3).

Pick: Avanesyan

Win probability: 54% Avanesyan · Market: -110 · Sets: 3 (42%) · most likely score 2-0 (32%)

A spot in the next round is at stake on Thursday, when Alina Charaeva goes up against Elina Avanesyan in the Sao Paulo round of 16. Elina Avanesyan is 6-4 across recent matches. Alina Charaeva has dropped 2 straight and sits at 5-5 over the last ten.

Elina Avanesyan simply rates much higher on hard, and our number follows from it. This one is close to a coin flip, and the lean toward Avanesyan is exactly that — a lean.

Jazmin Ortenzi vs. Paula Badosa

✓ Pick rightNailed it. We had Paula Badosa at 73% before the match, and Paula Badosa won 4-6 6-2 6-2.

Pick: Badosa

Win probability: 73% Badosa · Market: -668 · Sets: 2 (67%) · most likely score 2-0 (51%)

A spot in the next round is at stake on Thursday, when Jazmin Ortenzi goes up against Paula Badosa in the Sao Paulo round of 16. Paula Badosa comes in at 8 wins from the last ten. Jazmin Ortenzi is 5-5 across recent matches.

The serve is where this match separates: Badosa has been winning 65% of first-serve points to Ortenzi's 58.4%, and on hard that gap compounds fast. If Badosa plays anywhere close to a normal level, this ends in relatively comfortable fashion.
