The Madrid Open’s Round of 64 is officially underway, and Today’s schedule carries enough intrigue to keep even casual tennis fans glued to the action. Players who received first-round byes are stepping onto the clay at Caja Magica for the first time this week, facing opponents who already have a match and some momentum behind them. That dynamic shapes several of the predictions below.
Naomi Osaka opens cold in Madrid
Naomi Osaka begins her Madrid campaign against Colombian clay specialist Camila Osorio, and the matchup is closer than the rankings suggest. Osaka, seeded 14th at the tournament, carries a 2-1 head-to-head advantage over Osorio, but their history is complicated. Osorio handed Osaka a straight-set loss at last year’s Indian Wells before Osaka earned revenge at the same tournament this year, winning 6-1, 3-6, 6-1 in three sets.
The key concern for Osaka is rust. She has not played on clay yet in 2026, and Madrid will only be her third tournament since the Australian Open. Osorio, by contrast, already has a first-round win in Madrid under her belt. Osaka has historically struggled at this venue, never reaching the semifinals and losing in the second round or earlier on multiple occasions.
The first set figures to be tight, and the total number of games in that set is expected to clear 8.5. Osorio is worth backing as a live underdog, with a genuine chance to force a third set or win the match outright.
Best bet: Set total games over 8.5 and Osorio as an underdog play.
Leylah Fernandez should handle Grabher
Leylah Fernandez arrives in Madrid with form and confidence. Last week in Stuttgart, she pushed world No. 2 Elena Rybakina to the limit in the quarterfinals before falling in what was a genuinely competitive match. Fernandez holds a 2-0 head-to-head record over Julia Grabher, who upset Paula Badosa in the first round as a heavy underdog.
Grabher is playing with confidence, and that matters on clay. A straight-set win for Fernandez at short odds is a difficult price to justify. The more interesting angle is the game spread. Grabher is capable of keeping the deficit manageable even in defeat.
Best bet: Grabher +5.5 games as a value play.
Hailey Baptiste meets a dangerous Quevedo
Hailey Baptiste is ranked more than 100 spots above Kaitlin Quevedo, but her clay record this season raises questions. She lost to world No. 174 Iryna Shymanovich in Rouen, suggesting she is not at her best on the surface. Quevedo, meanwhile, just knocked out Venus Williams in the first round.
The Williams victory was a favorable draw, and Baptiste will present a sterner test. Still, Quevedo has shown she can compete. The safe play here is not to bet on an outright Quevedo win, but rather to back her to keep the match relatively close in a losing effort.
Best bet: Quevedo +4.5 games as a spread value play.
Swiatek is an overwhelming favorite against Snigur
Iga Swiatek has never faced Daria Snigur, but the matchup sets up heavily in the Polish player’s favor. Swiatek is one of the greatest clay-court players of her generation, and her new partnership with head coach Francisco Roig has drawn considerable attention. Snigur has struggled against elite opposition and is particularly uncomfortable against players who generate heavy topspin on returns.
Even accounting for Swiatek’s recent inconsistency, this is not a match that carries much uncertainty.
Best bet: Swiatek to win at any available price.
Fabian Marozsan and Opelka lead the men’s card
On the men’s side, Fabian Marozsan meets Ethan Quinn in what looks like a favorable matchup for the Hungarian. Quinn won their only previous meeting on clay, but that was in a Davis Cup qualifier rather than an ATP 1000 environment. Marozsan is a seasoned clay-court competitor, and Quinn is still developing at this level. Marozsan is expected to level their head-to-head in straight sets.
Reilly Opelka faces Nicolai Budkov Kjaer in a match that suits the American’s strengths. Opelka won their only previous encounter at the 2026 Australian Open in straight sets. His serve dominates on most surfaces, though clay does reduce his margin for error. Kjaer has a solid return game but cannot match Opelka’s overall firepower.
Best bets: Marozsan to win and Opelka to win.
