Top seeds Alcaraz and Swiatek into Madrid Open semifinals

MADRID: Carlos Alcaraz made sure he will get to celebrate his 20th birthday on the court at the Madrid Open come Friday.

The defending champion overcame a tough test from Karen Khachanov on Wednesday, rallying late in the second set for a hard-fought 6-4, 7-5 win that set up a semifinal against Borna Coric on his birthday.

It was Alcaraz’s 150th tour-level match, and his 117th victory to leave him with a winning percentage (78 percent) currently better than the likes of Pete Sampras, Boris Becker and Andre Agassi.

“My dream in tennis right now is to become one of the best tennis players in history,” Alcaraz said. “I know that this is a big dream, (it) probably is too big.

The top-seeded Spaniard improved to 27-2 this year, having dropped only one set in his last 19 victories. He will be playing in his third Masters 1000 semifinals of the season.

“I knew I had to keep fighting no matter what,” Alcaraz said. “I had to stay strong because I knew that I would have my opportunities, and gladly I took advantage of the first one that I had to close out the match.”
