The 2026 Mutua Madrid Open was underway at the Caja Magica in Madrid, Spain, and Friday’s betting board was already leaning hard toward a few familiar names. Jessica Pegula was among the players drawing attention as the tournament’s altitude and clay mix again shaped the day’s picks.
One of the clearest calls came in the Karolina Pliskova-Maria Sakkari matchup. Pliskova, 34, was backed to have a better than 50% chance of advancing against Sakkari, 30, with Madrid’s altitude expected to give her a slight edge. Sakkari was described as a weak server, holding at just 65.8% this year, while Pliskova was labeled a player who really can’t move anymore — a blunt reminder of how much the matchup depended on serve and pace rather than footspeed.
The Madrid card mattered today because the event is played at altitude, and that changes how clay-court matches can play out. Higher elevation can help serve-heavy players, which is why the betting focus kept coming back to profiles that fit the conditions better than the surface usually suggests. The picks also stretched beyond that one match, with other lines and matchups discussed across the Friday slate.
Ben Shelton drew some of the strongest market support elsewhere on the board. Nearly 98% of the tickets and handle were on Shelton, who opened at -237 at DraftKings and had moved to -200. He arrived in Madrid after winning a title in Munich last week, and the price movement showed how much the betting public was buying into that form. Dino Prizmic, by contrast, was noted for having played a lot of clay-court matches in his career, giving that matchup a different texture.
That is the friction in Madrid every spring: the surface is clay, but the altitude can make it play faster and open the door for players whose games would not usually look as comfortable on dirt. The numbers behind Shelton and the Pliskova-Sakkari matchup showed exactly how sharply bettors were adjusting to that reality. Jessica Pegula was part of the wider betting conversation, but the day’s clearest signal was that the market had already decided which kinds of players it trusted most in Madrid.
