Marcos Giron Prevails in Epic Five-Set Battle to Reach US Open Second Round

New York, August 25, 2025 - American Marcos Giron overcame Argentine Mariano Navone in a marathon first-round clash at the US Open, prevailing 6-0, 7-5, 4-6, 5-7, 6-4 on Monday at Court 11. The encounter lasted four hours and twelve minutes, marking Giron’s deepest run at Flushing Meadows to date.

Giron stamped his authority early, racing through the opening set without dropping a game before holding off a late surge from Navone in the second set 7-5. Navone fought back to force a decider, taking the third and fourth sets 6-4 and 7-5 respectively. In the decisive fifth frame, Giron regrouped to secure the crucial break at 5-4 and served out the match.

Statistically, Giron edged his opponent in points won, 173 to 153, and capitalized on 56 percent of break opportunities (9 of 16), compared to Navone’s 35 percent conversion rate (6 of 17). He also claimed $44,000 in prize money for the victory, bringing his US Open earnings this year to $154,000; another win in the second round would boost his total to $237,000.

Next up for Giron is a second-round showdown against France’s Benjamin Bonzi, with no head-to-head history between the two players. The winner will advance to the round of 32 and continue their chase of a first Grand Slam quarterfinal appearance.
