Daniil Medvedev has beaten Tomas Machac 6-3 6-2 in the second round of the BNP Paribas Open, the Russian’s first tournament since ascending to No.1 in the world.

Medvedev made quick work of his Czech opponent, finishing Machac off in just over an hour. The Russian won 80 per cent of his first-serve points and saved the lone break point he faced.

Rafael Nadal didn’t have it as easy in opening his pursuit of a fourth title at Indian Wells.

He got pushed to the limit by practice partner Sebastian Korda before winning 6-2 1-6 7-6 (7-3), giving Nadal a 16-0 record this year.

He won the Australian Open in January for his record 21st major championship, breaking a tie with Roger Federer and Novak Djokovic. He won other titles in Melbourne and in Mexico.

Nadal trailed 5-2 in the third set before winning four straight games with two breaks of Korda to take a 6-5 lead. Korda held at 6-all to force the tiebreaker. The 38th-ranked Korda led 3-2 and then Nadal reeled off five straight points to close out the marathon match.

Before the match, Nadal withdrew from the Miami Open, which begins March 21. He is managing a chronic condition in his left foot.

Earlier this week, Medvedev received a trophy commemorating his status atop the ATP Tour rankings. He displaced Djokovic, who wasn’t allowed to enter the US to play because he’s not vaccinated against COVID-19.

Medvedev has to reach the quarter-finals in the desert to stay in the top spot.

“If I’m going to lose it because I’m either going to play a bad match or my opponent is going to play an amazing one, there is the next tournament in Miami,” he said.

“That’s how tennis is, every week is a new story. Right now it’s Indian Wells week and I want to make it a good story.”

Medvedev is among players from Russia and Belarus competing at Indian Wells without flags, symbols or anthems as a result of Russia’s invasion of Ukraine. The decision to eliminate their national identity was made by the International Tennis Federation and both tours.

“It’s definitely not for me to decide,” Medvedev said. “I follow the rules. I want to play my favourite sport.”
