Madrid, April 30
Francisco Cerundolo recorded an upset 7-5, 6-3 win over two-time champion Alexander Zverev at Madrid Open. The Argentine ended German's seven-match winning streak, which dated back to the start of his Munich title run.
In a rematch of their fourth-round encounter from one year ago, Cerundolo, who also beat Zverev this season in Buenos Aires, saved the only break point he faced, according to ATP Stats.
"I'm super happy because I know he loves playing here. He told me last year when I beat him. He's an incredible player. I have a great relationship with him, so super happy to get another win and to be in the quarter-finals again," Cerundolo said.
With the win, Cerundolo joined Arthur Fils as the only players to reach three ATP Masters 1000 quarterfinals this season. He also leads the ATP Tour with seven quarter-finals and 15 clay-court wins on the 2025 season, ATP reports.
While Cerundolo is through to his seventh career Masters 1000 quarter-final, Zverev was denied his 100th quarter-final appearance at that prestigious level.
