MADRID - World ​number one Jannik Sinner held off 19-year-old wildcard Rafael Jodar to ‌win 6-2 7-6(0) in the Madrid Open quarterfinals on Wednesday, becoming the sixth player to reach the semifinals of all nine ATP 1000 Masters tournaments.

Sinner saved five break points in the second ​set and won 11 points in a row to secure victory over ​the Spaniard.

"He pushed me to the limit, he's an incredible player... I'm ⁠incredibly happy, it's been a very high quality match," Sinner said in his ​post-match interview.

The 24-year-old Italian produced a disciplined performance in the first set, breaking the ​local favorite twice to take a 5-2 lead, before sealing the set with a fierce backhand.

Jodar, who won his first tour title in Morocco this month, threatened to pull 4-2 ahead in ​the second set, but Sinner saved two break points to stay level at 3-3.

A ​double fault from the Italian put Jodar on the verge of another break, but Sinner saved three ‌break ⁠points with a strong crosscourt forehand and two backhand winners that brushed the sideline.

Sinner went 40-15 up in the next game but Jodar saved three break points before taking it.

Sinner, chasing his second claycourt title this season after winning the Monte-Carlo Masters, ​dominated the tiebreak and ​sealed victory with ⁠a forehand that Jodar could not reach.

He will next face Arthur Fils, who beat Jiri Lehecka 6-3 6-4 later in the ​day, extending his winning streak to nine matches. The 21st ​seed became ⁠the first Frenchman to reach the semifinals in Madrid since 2009, avenging his recent Miami Open loss to Lehecka with a dominant, 74-minute performance in which he did not ⁠face a ​single break point.

Like Sinner, Fils remains undefeated on ​clay this season, building on his triumph at the Barcelona Open earlier this month.
