Sinner enters the semifinal as the world No. 1 and top seed after beating Spanish wildcard Rafael Jodar 6-2, 7-6(0), a win that made him the sixth player to reach the semifinals at all nine ATP Masters 1000 events. Fils, meanwhile, is one of the hottest players on clay, beating Jiri Lehecka 6-3, 6-4 to extend his clay winning streak to nine matches and become the first Frenchman to reach the Madrid semifinals since the tournament moved to clay in 2009.

Sinner leads their head-to-head 1-0, but both players are unbeaten on clay this season, making this a high-level form-vs-form matchup.

The other semifinal has a clear underdog storyline, as Blockx has turned a late main-draw opportunity into the biggest run of his career. The 21-year-old Belgian knocked off defending champion Casper Ruud 6-4, 6-4 after also beating seeded players Brandon Nakashima, Felix Auger-Aliassime, and Francisco Cerundolo. Zverev brings the experience edge as the No. 2 seed and a two-time Madrid champion, and he looked sharp in a 6-1, 6-4 win over Flavio Cobolli with 12 aces and 23 winners.

Blockx and Zverev are meeting for the first time, with Zverev chasing another Madrid final and Blockx trying to complete one of the tournament’s biggest surprises.

Somehow on Sunday, Coco Gauff prevailed in her match over Sorana Cirstea. The three set affair pushed the ill Gauff to her physical limits.

Gauff was forced to take the rest of the day off. She did not take the court with Robin Montgomery for their planned doubles match.

We hope Gauff is recuperating, and we suggest that if she is still under the weather and decides to play on Monday, that she should bring back the baseball cap.

Why Gauff needs the rally cap

She wore it at the Miami Open in her first tournament after retiring from Indian Wells with the arm injury. At the time, Gauff explained that the cap was out of necessity because she did not feel like doing her hair. She made it to the Miami Open final wearing the now retired cap.

She personally did not like the cap and proclaimed it was one-and-done in Miami. The signature headband has been back since.

Reviving the cap for the Mutua Madrid Open latter rounds may help shield her face from the sun. Gauff seemed bothered by the heat much more than usual on Sunday, because of her sickness, and was needing ice packs often.

Also, everyone will be honed in on her more than usual so the cap blocks the inquisitive eyes on her. Aryna Sabalenka wore one in the Miami Open a few years ago for similar reasons.

Watch Gauff (health permitting) and the rest of the American women, Hailey Baptiste, Ann Li, and Caty McNally, in the Round of 16 at the Mutua Madrid Open on Monday, April 26 on Tennis Channel.
