Jannik Sinner has done it again. The 24-year-old Italian world No. 1 made history on Sunday at the Mutua Madrid Open, becoming the first player ever to win five consecutive ATP Masters 1000 titles. He powered past Germany's Alexander Zverev 6-1, 6-2 in a final that was as dominant as the scoreline suggests.

This incredible run began back in November, when Sinner captured the Paris Masters—a tournament where he set a record for losing the fewest games (29) in the process. From there, the streak only grew stronger. He won the BNP Paribas Open at Indian Wells in March without dropping a single set, a feat he repeated at the Miami Open. Then came victories at the Monte-Carlo Masters and now Madrid, all within a remarkable nine-week span.

Against the second-seeded Zverev, Sinner was nearly flawless. He never faced a break point, while converting all four of his own chances. His first serve was a weapon: winning 27 of 29 points when his first serve landed in—a staggering 93.1 percent—and averaging 130 mph, six mph faster than Zverev. The first set took just 25 minutes; the second, 31. It was Sinner's ninth straight win over Zverev, and the German knew he was up against something special.

"Super sorry for the final," Zverev told the crowd. "Was not my best day. But congratulations to Jannik. Best player in the world, by far, at the moment. No chance for most of the people, for us, at the moment against you."

Sinner, ever humble, credited his team. "My team, thanks for pushing me, thanks for believing in me," he said. "I know we are doing something incredible, so thank you so much."

Now, the tour moves to Rome for the Italian Open, where Sinner will have a chance to add another chapter to his story. If he wins there, he'll join Novak Djokovic as the only players to have won all nine ATP Masters 1000 tournaments. Given his current form, that milestone feels less like a question of if and more like when.
