Twenty-year-old Martin Landaluce earned a milestone win Sunday when he upset Karen Khachanov 6-3, 7-6(2) in the third round of the Miami Open presented by Itau. With the victory, the #NextGenATP star advanced to the fourth round of an ATP Masters 1000 event for the first time.

In his maiden Lexus ATP Head2Head meeting against Khachanov, the No. 151 player in the PIF ATP Rankings played with authority and composure. Despite taking on an opponent nine years his senior, Landaluce controlled the match from the outset, striking 25 winners compared to just 12 from Khachanov.

The 2025 Next Gen ATP Finals competitor’s serve also proved effective. Landaluce won 78 per cent (23/32) of his first-serve points, according to Infosys ATP Stats, to seal the upset in one hour and 32 minutes.

The result is the latest highlight in what is quickly becoming a defining week for Landaluce in Miami. Having trailed Thiago Agustin Tirante by a set and a break in the final round of qualifying, he nearly did not earn his place in the main draw.

But Landaluce has been on a tear since, beating in-form American veteran Marcos Giron in the first round of the main draw and upsetting 17th seed Luciano Darderi in the second round. Following his third-round win against Khachanov, the 20-year-old jumped 13 spots to No. 123 in the PIF ATP Live Rankings.

Coming into the tournament, the 2022 US Open boys’ champion owned just two tour-level wins (2-14), the first of which came in Miami in 2024 against Jaume Munar. 

The next test for the young Spaniard will be a fourth-round meeting with Sebastian Korda, who upset World No. 1 Carlos Alcaraz earlier on Sunday.
