The 30 year-old joins the likes of Nick Kyrgios, Rinky Hijikata and Tristan Schoolkate in the round of 64, where they will be joined by compatriots Alex de Minaur and Alexei Popyrin. 

Towering local hope Reilly Opelka claimed his first ATP Masters 1000 win since 2022.

Standing at six feet, 11 inches, the American - equal with Ivo Karlovic as the tallest ever professional men's players - finished with a flourish behind his serve to defeat countryman Christopher Eubanks 6-3, 7-6.

Opelka won all 26 of his first-serve points in the second set and fittingly sealed the 85-minute win with an ace out wide on the Deuce court.

“The first set I didn’t serve well at all, I didn’t know what was going on,” said Opelka, who landed 16 of 30 first serves in the opening set. “I waited until the second set to address it, regroup and think about some technical things. 

"My toss was way off, that happens to me sometimes. As soon as I made that adjustment, it clicked straight away and I knew it was going to be tougher to break me in the second, even though he didn’t break in the first. That gave me a lot of confidence.”

Opelka reached his seventh ATP Tour final in Brisbane in January and is now 9-5 on the season. After defeating the 6' 7" Eubanks for the second time in as many months, the 27 year-old will next face 11th seed and last week's Indian Wells finalist, Holger Rune.

In other action at the ATP Masters 1000 event, Bu Yunchaokete produced a rock-solid performance to see off former World No. 8 Cameron Norrie 6-4, 6-2 in 79 minutes. 

The 23year-old, who did not face a single break point against the Briton, is now one spot off his career high at No. 66 in the PIF ATP Live Rankings. Buyunchaokete will meet 10th seed De Minaur in the second round.

Zizou Bergs claimed his third consecutive win over Nuno Borges this year by moving past the Portuguese 7-6, 7-5. Bergs, who is at a career-high No. 51 in the PIF ATP Rankings, takes on eighth seed Andrey Rublev in the second round.

Qualifiers Jacob Fearnley and Thiago Agustin Tirante both advanced on Day 2 in Miami. Fearnley survived Benjamin Bonzi 7-6(6), 2-6, 6-4 to set a clash with top seed Alexander Zverev, which is a repeat of their Australian Open third-round match in January.

Tirante reeled off five consecutive games from 1-3 in the final set to overcome Flavio Cobolli 6-1, 3-6, 6-3 and set a second-round meeting with 27th seed Denis Shapovalov.

Lucky loser Hugo Gaston advanced past Yoshihito Nishioka 6-3, 3-1 before the Japanese was forced to retire. Gaston entered the main draw after former World No. 4 and 2016 Miami finalist Kei Nishikori withdrew due to a back injury.

Spaniard Alejandro Davidovich Fokina overcame Jan-Lennard Struff 7-6(3), 6-3 

While Canadian Gabriel Diallo beat Tomas Martin Etcheverry 6-3, 6-0.
