Alexander Zverev's quest for a maiden Grand Slam title suffered another devastating blow as Jannik Sinner dismantled him in the 2026 Madrid Open final. The Italian star cruised to a commanding 6-1, 6-2 victory, claiming his first Madrid crown and extending his ATP Masters 1000 win streak to five consecutive titles—a feat never before achieved since the format's inception.

For Zverev, the defeat was more than just another runner-up finish. It marked his ninth straight loss to Sinner, a streak stretching back to 2023 when the German last triumphed in a five-set thriller at the US Open. Since then, Sinner has dominated their rivalry, not dropping a single set in their last six meetings. The last time Zverev even managed to take a set off the Italian was during the 2025 Vienna final.

Former British player Colin Fleming, speaking to Sky Sports, expressed sympathy for Zverev's plight. "I feel a bit gutted for Zverev in a way. As good as Sinner was, Zverev just didn't perform," Fleming said. "The first point of the match was one of Zverev's best—I thought he was up for it. He pinned Sinner in the backhand corner. Then he lost the next four points, played a poor first service game, and got broken. Honestly, the match felt over right there."

Fleming added that Zverev's body language told the story: "At 2-0 in the first set, he looked completely deflated. His main driver is to win a Grand Slam, and unfortunately for Zverev, it felt like he took a big step further away from that today. That's going to be pretty tough for him to come to terms with."

Sinner's nine-match win streak over Zverev ties the longest such run against a fellow top-five player in ATP history. The only other player to achieve this? Roger Federer, who beat Andy Roddick nine times in a row between 2003 and 2007. For Zverev, the road to a major title now seems steeper than ever, as Sinner continues to cement his place among the sport's elite.
