    Tennis Picks Today: 5 Best Bets & Predictions Ft. Venus Williams vs Kaitlin Quevedo, Paula Badosa vs Julia Grabher | April 21, 2026

    Seven-time Grand Slam champion Venus Williams will be in action, as she begins her run at the Madrid Open against Kaitlin Quevedo in R1 on Tuesday. Homegirl Paula Badosa also begins her run at the prestigious WTA 1000 event against Julia Grabher in R1.

    Today, we have five women’s singles matches from the Madrid Open for you, and we will provide the best bets, reliable predictions, and top tennis picks to help you make lucrative wagers. The matches will include some R1 contests and some second-round qualifiers.

    Top Tennis Picks and Best Bets Today

    Kaitlin Quevedo vs. Venus Williams: Total Games Over 19.5 (-110)

    This will be the first professional meeting on tour between the veteran American and the Spanish rising star. Both players have been battling inconsistencies on the court this season. Quevedo is 11-7 for the year, with a 3-2 record on clay, while Williams is 0-6 and is yet to register her maiden singles win of the season.

    We don’t expect Williams to pull off a miracle today against the 20-year-old Spaniard, simply because the veteran hasn’t been able to play her brand of tennis since the start of 2026.

    Moreover, her agile and sluggish movement on the court will only benefit the homegirl today. Take Quevedo for the win, but expect Williams to win at least 7-8 games in the match, thereby making our pick a safe bet for non-risk takers.

    Paula Badosa vs. Julia Grabher: Total Games in Set 1, 9-10 Games (+115)

    This will be the second meeting between Badosa and Grabher, and the first since 2016, when they met in the opening round of the Brescia Open (clay). While the Spaniard had won the earlier meeting in three sets, we expect her to ride the home advantage and win the match in two sets against the Austrian today.

    Both players are contending with losing records on clay, but the script might be favoring the home girl today. Expect Badosa to register at least one service break in each set, thereby not allowing Grabher to get past the 3 or 4-game mark in either set, ultimately making our pick a bit challenging but worthy to wager upon.

    Alycia Parks vs. Ksenia Efremova: Parks to Win in Two Sets

    This will be the first meeting between Alycia Parks and the French teenager Ksenia Efremova. While the 16-year-old had won the Australian Open Juniors title this year, she has struggled with consistency on tour ever since, battling an injury and playing just one tournament since her triumph Down Under.

    This will only be her second WTA event of the year, and Parks might just prove to be a lot of firepower for the young teen to handle. This match should be a one-sided affair; our pick is Parks in straight sets, advancing to the main draw of the Madrid Open.

    Sloane Stephens vs. Anhelina Kalinina: Total 3 Sets to be Played in the Match (+200)

    This will be the fourth meeting between the former US Open champion and the 29-year-old Ukrainian, who has showcased streaks of brilliance in multiple tournaments this season.

    Stephens leads the head-to-head battle 2-1, but both her victories against Kalinina have come on the hard surface, while Kalinina’s only win has come in the opening round of the 2022 Madrid Open.

    The Ukrainian had won that contest in straight sets. While we expect her to register her second win on clay against the American today, Stephens is not expected to go down without a fight, and we predict an all-out three-setter between the duo in the final round of the qualifiers today.

    Peyton Stearns vs. Lois Boisson: Set Spread, Stearns -1.5 (-110)

    This will be the first meeting between reigning ATX Open champion Peyton Stearns and Lois Boisson. The 22-year-old French sensation is making a comeback to tour after almost seven months away, battling injuries and some prolonged medical deadlines.

    Boisson is most famous for her dreamy semifinal run at the French Open last year, which was ended by the eventual champion Coco Gauff. This will be Boisson’s first competitive match of the season, and while the Frenchwoman showcased class on clay last year, we don’t expect her to come out of the blocks that quickly.

    Therefore, expect Stearns to win two sets in the match today and advance to the Round of 64.
