Stefanos Tsitsipas has overcome a mid-match hiccup against Kei Nishikori to advance to the Miami Open round of 16.
Greek second seed Tsitsipas dominated the first and third sets in a 6-3 3-6 6-1 victory over the resurgent Nishikori, who is climbing his way back up the rankings in his comeback from a long layoff through injury.
Tsitsipas broke early to build a 3-0 lead and didn't take his foot off the gas as he dropped only four points behind his serve during the set.
Nishikori grabbed the momentum early in the second set on his way to squaring the match.
But Tsitsipas, who fired 32 winners, regained the ascendancy with two further breaks of serve before he closed it out on his first match point.
Lorenzo Sonego, the 24th seed, is next for Tsitsipas after the Italian defeated Daniel Elahi Galan 7-6 (8-6) 6-3.
Andrey Rublev's phenomenal run in 2021 continued when rolled past Marton Fucsovics 6-2 6-1 - beating the Hungarian for the third time in the past 22 days.
That doesn't even include a walkover victory over Fucsovics in Qatar in that span.
While world No.8 Rublev has won all of their recent encounters in straight sets this clash was the most lopsided.
The 23-year-old was on fire to such an extent that Fucsovic told Rublev he didn't want to play him again this year.
The Russian even cracked a laugh as he walked to the net, knowing he had played a flawless match as he racked up his season-leading 18th win this year.
Marin Cilic, who produced a clinical performance earlier on Monday to end the run of Italy's Lorenzo Musetti 6-3 6-4, is drawn to face Rublev in the fourth round.
After his maiden ATP Masters 1000 victory in the first round, Sebastian Korda got his second consecutive win over a seeded opponent with a 6-3 6-0 romp against Aslan Karatsev of Russia.
The young American became just the third player this year to defeat Karatsev - the others being Novak Djokovic and Dominic Thiem.
Korda's reward is a showdown with fifth-seeded Diego Schwartzman of Argentina, while Polish 26th seed Hubert Hurkacz upset sixth-seeded Denis Shapovalov 6-3 7-6 (8-6) and will face another Canadian in the last 16, in 12th-seeded Milos Raonic.
