The 25th-seeded Argentine powered to a 6-2, 7-5 third-round victory against Felix Auger-Aliassime on Monday at the ATP Masters 1000 event in Florida. Cerundolo took control early with some blistering baseline play against the World No. 6 and dug deep in the face of a late Auger-Aliassime resurgence to wrap a one-hour, 44-minute win on Grandstand.

“I’m very happy to be back again in the round of 16 here, in a Masters 1000, here in Miami,” said Cerundolo after his 10th tour-level win of the year. “I’m super happy that I’m playing as well as last year, super happy with my level, and [hope] to keep going.”

The pair had last clashed just two weeks ago in the third round at Indian Wells, where Auger-Aliassime ran out a straight-sets winner. On Monday, Cerundolo expertly used the faster Miami conditions to engineer his revenge, constantly pressuring the fifth seed with a barrage of fizzing forehands.

Even after Auger-Aliassme reclaimed a break to level at 4-4 in the second set, the 24-year-old continued to strike the ball confidently. Cerundolo ended with 12 winners to Auger-Aliassime’s seven and converted four of six break points he earned for his third Top 10 career victory. The Argentine now holds an 8-1 record in Miami, and he will look to improve that further on Tuesday when he takes on 12th seed Frances Tiafoe or Lorenzo Sonego in the fourth round.

“One key was that I read his serve better,” said Cerundolo, reflecting on how different Monday’s match had been to his losses against Auger-Aliassime at January’s Australian Open and in Indian Wells. “I think I played much better than the other two matches.

“I had more confidence today than the previous months, so probably that was another key. My level was super high today. I served well, only one game that I made two double-faults, and I only faced [one other] break point. So I’m super happy.”
