Italy's Jannik Sinner eased into the semifinals of the Miami Open after a comfortable 6-3, 6-1 win over Finland's Emil Ruusuvuori on Wednesday.
The game was delayed for two hours by rain with Sinner 2-0 up in the second set but the stoppage did nothing to change the momentum of the match.
In the last four, Sinner will face the winner of the other quarterfinal between world No 1 Carlos Alcaraz and American Taylor Fritz which was postponed due to heavy rain on Wednesday and is expected to be played on Thursday.
The 23-year-old Ruusuvuori was the first Finnish player to feature in a Masters 1000 quarterfinal since Jarkko Nieminen a decade ago, but he came up against Sinner in determined mood.
The 21-year-old from South Tyrol has not dropped a set so far in Miami and he coped well with the first break point of the match, holding in the fourth game.
The Italian, who has not lost to a player outside the top 50 this year, never looked back after that brief threat, breaking the Finn's serve for 3-2 and again to win the set.
An early break in the second further established his control of the match and while the rain made him wait for victory, he needed just 74 minutes on court to finish off the 54th-ranked Finn.
"I just won the important points, especially in the first set, and I am happy with my level today," said Sinner.
"After the rain, the condition was different and I think I adapted well," he added.
With his 20-4 record, Sinner could face another semifinal meeting with Alcaraz who beat him in the last four in Indian Wells earlier this month.
While Sinner said he would see both the Spaniard and Fritz as challenging opponents, it is clear he would relish the chance of revenge against Alcaraz, who also beat the Italian en route to the US Open title in September.
"I would be happy to play again him again because I look forward to these kind of matches. I feel like he makes me a better player," he said.
