World No. 1 Carlos Alcaraz was dominant on his serve during a 6-1, 7-6 (2) win over 12th-seeded Casper Ruud in the Round of 16 at the BNP Paribas Open on Wednesday in Indian Wells, Calif.

The Spaniard never faced break point and lost only nine of his 49 service points in all, including going 29 for 33 on first-service points (87.9%). He fired seven aces.

The first set was a breeze, as he broke the serve of his Norwegian foe twice right away for a 4-0 lead. Ruud was better in the second set and held serve throughout, but Alcaraz took the first four points of the tiebreaker before winning on his second match point.

He'll take on British 27th seed Cameron Norrie in the quarterfinals.

'I'm just really happy about playing that kind of level,' said Alcaraz, the two-time Indian Wells champion who became the youngest man to reach the quarterfinals five times. 'I'm really happy to get through and hopefully (I can) play at this level in the next round.

'I think I can have fun and enjoy, but I can also turn my mind and focus again. I try to play my best tennis on every point, but when a point deserves a smile, I gotta do that. That's what happened today. Casper played some great points, and I had to enjoy that. That's why we both play tennis.'

Norrie eased past Australian Rinky Hijikata 6-4, 6-2. Norrie broke Hijikata's serve three times in six opportunities and also went 8-of-13 on net points.

Russian 11th seed Daniil Medvedev also advanced to the quarterfinals by beating American Alex Michelsen 6-2, 6-4. Medvedev will draw the winner between No. 3 Novak Djokovic of Serbia and No. 14 Jack Draper of Great Britain.

Medvedev finished with a 9-1 edge in aces and saved 4 of 5 break points along the way. He was aggressive, hitting 34 winners and taking 9 of 10 net points.

'When I'm in confidence, I'm an aggressive player,' Medvedev said. '... So when I'm hitting the ball the way I hit now, I can be aggressive and can put a lot of pressure on my opponents and still being able to be great in defense, and that's what makes it tough.'

Michelsen, a 21-year-old California native, was vying for his second quarterfinal berth at an ATP 1000 event following the Canadian Open last year.

'It's a great tournament,' Michelsen said. 'I had to beat a lot of good guys to get to the fourth round, and I'm playing some good ball right now, and played a guy (Medvedev) who we just talked about, it's a tough matchup for me. That's tennis. Life moves on, and on to Miami in a couple days. Yeah, feeling good.'
