Hold strength tells the story — 61.8% versus 57.5% on first-serve points in Riera's favor. This one is close to a coin flip, and the lean toward Riera is exactly that — a lean.

Diane Parry vs. Peyton Stearns

✗ Pick wrongA miss: Diane Parry at 60% lost to Peyton Stearns (6-2 7-5).

Pick: Parry

Alycia Parks vs. Sara Bejlek

✓ Pick rightNailed it. We had Sara Bejlek at 66% before the match, and Sara Bejlek won 6-4 6-3.

Pick: Bejlek

Sara Bejlek simply rates much higher on hard, and our number follows from it. Bejlek should have enough here, though Parks has the tools to make the scoreboard uncomfortable.

Elsa Jacquemot vs. Liudmila Samsonova

✓ Pick rightWe got this one right. Liudmila Samsonova was our 58% pick, and won 7-6 6-2.

Pick: Samsonova

Win probability: 58% Samsonova · Market: -312 · Sets: 2 (64%) · most likely score 2-0 (38%)

Hold strength tells the story — 69.2% versus 64.4% on first-serve points in Samsonova's favor. Little separates them; Samsonova gets the nod on the finest of margins.

Cristina Bucsa vs. Panna Udvardy

✓ Pick rightNailed it. We had Cristina Bucsa at 55% before the match, and Cristina Bucsa won 6-4 6-4.

Pick: Bucsa

Cristina Bucsa simply rates much higher on hard, and our number follows from it. Little separates them; Bucsa gets the nod on the finest of margins.

Lucrezia Stefanini vs. Nadia Podoroska

✓ Pick rightThis one lands on the correct side of the ledger: 59% on Nadia Podoroska, who won 6-3 6-4.

Pick: PodoroskaUpset call

Upset call: the market favors Stefanini; our numbers say Podoroska.

Win probability: 59% Podoroska · Market: +190 · Sets: 2 (62%) · most likely score 2-0 (38%)

Tuesday's Sao Paulo round of 32 pits Lucrezia Stefanini against Nadia Podoroska on hard. Nadia Podoroska is 3-7 across recent matches. Lucrezia Stefanini has won 4 of the last 10.

The serve is where this match separates: Podoroska has been winning 62.2% of first-serve points to Stefanini's 55%, and on hard that gap compounds fast. A tiebreak or two would surprise nobody, with Podoroska fractionally more likely to land the big points.
