2 matches are on Tuesday's card at Sao Paulo, and we have a pick for every one of them. The headline act: Elina Avanesyan against Julia Riera in the round of 32. Our calls: Riera over Avanesyan, Podoroska over Stefanini.

The boldest call on the card: Podoroska over Stefanini — the market disagrees with us there.

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.

Elina Avanesyan vs. Julia Riera

✗ Pick wrongWe got this one wrong. Our final number was 50% on Julia Riera; Elina Avanesyan won 6-2 6-4.

Pick: Riera
