Jannik Sinner continues ATP Masters 1000 run in Rome

Jannik Sinner is just two wins away from securing his sixth straight ATP Masters 1000 title, following another strong performance in Rome.

Sinner dispatched Andrey Rublev in straight sets, 6-2, 6-4, to reach the semifinals of the Italian Open.

The world number one also moved past Novak Djokovic for the most consecutive match wins at ATP Masters 1000 events, now up to a remarkable 32.

Sinner also joined Rafael Nadal as the only players to reach the semifinals at all of the first five Masters tournaments in a single season.

And while it was another straight-sets win for Sinner, there were moments when he wasn’t at his best during that second set.

Jannik Sinner talks about his fitness after the latest win in Rome

Sinner’s first-serve percentage dropped to 39% during the second set, opening the door for Rublev to make a push.

While the Russian did manage to break serve, he couldn’t do enough to turn things around.

Sinner appeared to be flagging late in the match but reassured everyone afterwards that there’s no cause for concern.

“I’m going to be all right,” Sinner said when asked about any issues. “It’s normal that one day in the tournament you are slightly tired. I played a lot also. It has been very long days for me.”

Despite not looking at his sharpest, he was pleased with how he handled it: “But look, I’m happy how I end the situation. We try to keep going.”
