World No.2 Jannik Sinner bested Frances Tiafoe to qualify for the Miami Open semifinal. Sinner registered a comprehensive 6-2, 6-2 win over the American to continue his rich form at the Hard Rock Stadium in Florida.

The Italian raced to a dominant 71-minute triumph as he brought his A-game to the court. Sinner said he gained confidence after breaking Tiafoe early in the match.

“I feel like starting the match is very important,” said Sinner. “When you start by going a break up, it gives you already a slightly good confidence. At the same time, they might be very aggressive, so I try to stay as compact as possible with my shots. Also mentally, there can be some ups and downs on both sides, so I try to stay very calm and take the chances I can get. I think today, that was the key.”

Sinner dropped just nine points on serve on Thursday as he was at his absolute best against the American. 

The Italian said it is crucial for him to keep the hunger of winning and stay calm and relaxed off the court. 

“To be hungry [for more success], I think is quite natural,” said Sinner after his 10th consecutive match win. “Mentally, you have to stay calm and be relaxed also off the court, because I played a lot of tennis in the past three or four weeks with all the practice sessions and everything. I’m trying to keep going. I know this is my last tournament on hard courts before going on clay, so I’m very happy to make the semis again.”

Sinner will next take on Alexander Zverev in the semifinal on Friday.
