Marcos Giron Defeats Adrian Mannarino to Reach Dallas Open Final

Marcos Giron is one win away from his first ATP Tour title…

The 30-year-old Colombian American tennis player, unseeded in the tournament, beat No. 4 seed Adrian Mannarino of France, 6-1, 6-3, in the semifinals at the Dallas Open.

Marcos GironGiron took a 4-0 lead in the first set a day after going up 5-0 in a straight-set win over Tiafoe, who was the highest-ranked player in the tournament at No. 14.

The first break of the second set came when Giron made a lunging save with a forehand, then ran down Mannarino’s volley for a backhand crosscourt passing shot and a 5-3 lead.

Giron, who hasn’t lost a service game in four matches in the tournament, had little trouble closing out the match on his serve.

With three victories over seeded opponents, Giron has a chance to surpass his career-best ranking of 49th from 2022.

Giron reached the semifinals in Dallas two years ago, losing a three-setter to Jenson Brooksby while having match points. The final two sets went to tiebreakers.


“That stuck with me, and that’s hard,” Giron said. “I have experience. I know what it’s like to lose. I know what it’s like to win. Having a big win yesterday was awesome, and I’m really, really happy to be able to come back today.”

Giron, who beat top-seeded American Frances Tiafoe in the quarterfinals, is making his second trip to a final. He previously appeared in the finals of the 2022 San Diego Open, where he lost to Brandon Nakashima.

He’ll face second-seeded Tommy Paul in Sunday’s final.
