Best Sunday Wimbledon picks:

• Aryna Sabalenka/Elise Mertens Under 9.5 aces (+100)
• Nicolas Jarry/Cameron Norrie Under 31.5 aces (-120)
• Andrey Rublev/Carlos Alcaraz Under 23.5 aces (-120)
• Parlay these picks for +572 odds (odds subject to change)

Aryna Sabalenka/Elise Mertens Under 9.5 aces (+100)

Sabalenka is known for her elite serving, but her ace numbers have actually not been overly impressive this year. She is only averaging 3.3 aces per match, and she has only had more than five in one of her grass-court matches this season. Mertens has finished with four or fewer aces in four of her last five matches. These two have squared off four times since the beginning of 2023, and they have gone Under 9.5 aces in all of those meetings. This is expected to be a 2-0 victory for Sabalenka, which would limit the amount of ace opportunities. bet365 sportsbook has the best price, and a bet365 bonus code can give you even more value.

Nicolas Jarry/Cameron Norrie Under 31.5 aces (-120)

The conditions are expected to be on the slower side again on Sunday, as high humidity, moderate wind and cooler temperatures are in the forecast. There is also a significant chance of rain, so the roof could be closed and that would slow the surface down as well. Norrie racked up 35 aces in his first two matches of the tournament, but he came back to earth with six aces in his third-round win over Mattia Bellucci. Jarry has allowed eight or fewer aces in his four best-of-five matches in London (including the final round of qualifying), and his time on court is starting to become a factor. Anything less than a five-set match creates strong value on the Under. bet365 has the best price for this prop as well.

Andrey Rublev/Carlos Alcaraz Under 23.5 aces (-120)

This is the first grand-slam meeting between these top-15 players, but they have met three times since 2022. They have both held each other to five aces or fewer on multiple occasions, and the slower conditions will benefit this prop as well. While Rublev has recorded double-digit aces in his first three matches, he did not have more than 14 in any of them. He is facing one of the toughest players to ace, so his total should be significantly lower on Sunday. Alcaraz ranks outside the top 50 on the ATP Tour in aces per match over the last 52 weeks, making this is a nice spot to play the Under. You can find this prop at bet365.
