No. 1 Jannik Sinner cruises into Round of 16 at Wimbledon 2025 - ESPN

As well as Jannik Sinner is playing at Wimbledon, he doesn't appear to need much in the way of help. Still, he got some Saturday when his opponent, Pedro Martinez, was dealing with a problematic shoulder that compromised his serve.

The No. 1-ranked Sinner has dropped a total of 17 games so far, made his way to the fourth round for the seventh consecutive Grand Slam tournament — he's collected three such trophies in that span — and never was truly in trouble during a 6-1, 6-3, 6-1 victory over No. 52 Martinez.

There's been zero sign of any sort of inability on Sinner's part to move past last month's French Open final, which he lost to Carlos Alcaraz in five sets despite taking the first two and holding three championship points.

Against Martinez, Sinner went up 5-0 after 20 minutes. During that stretch of 29 points, Martinez managed just one winner, while Sinner accumulated 10.

That aspect of Martinez's game improved incrementally, but the only, ever-so-brief, moment of intrigue at Centre Court came in the second set, about 75 minutes in, with Sinner
