The Best Challenger in the World Is in a Park in Mexico City. Why Is Nobody Talking About It?
The Mexico City Open just completed its fifth edition. The ATP called it the best Challenger in the world. The court is named after a man most casual tennis fans have never heard of. This is the tournament that explains everything about where tennis is heading.
The Mexico City Open tennis tournament is held at the Centro Deportivo Chapultepec, inside one of the largest urban parks in the world, on a court named after Rafael “Pelón” Osuna — Mexico’s greatest tennis player, a man who won Wimbledon doubles and the US Open doubles in the 1960s and died in a plane crash at 30. The stands sell out for the final rounds. The ATP named it the best Challenger tournament in the world in 2024. And almost nobody outside of Latin America is talking about it.
This is the kind of tournament that the tennis world needs more of and produces less often than it should: a Challenger that actually feels like something. Not a placeholder on the calendar between bigger events. Not a stepping stone that the players tolerate on their way to somewhere else. A genuine sporting occasion, with a city behind it, a local story threaded through it, and a level of organization that made the ATP’s governing body give it an award they’ve never given a Mexican tournament before.
Five editions in, the Mexico City Open has outgrown its category. And the organizers know it.
The park, the court, and the name on the sign
What the Mexico City Open Tennis Tournament Actually Is — And Why the Venue Matters
The Centro Deportivo Chapultepec is not your typical tennis venue. It sits inside the Bosque de Chapultepec — one of the largest urban parks in the world, a massive green lung in the middle of a city of 22 million people — but the club itself is one of Mexico City’s most exclusive private sports facilities. Memberships are expensive and hard to come by. For 51 weeks of the year, the courts belong to members only.
Then comes tournament week. For seven days in April, the gates open. Tickets go on sale. The city gets access to a space it normally can’t enter, and the space gets something it normally doesn’t have: a crowd that didn’t grow up there. That dynamic — exclusive venue, suddenly public — gives the tournament a specific energy that’s hard to manufacture anywhere else. You’re not watching tennis in a purpose-built arena. You’re watching it inside a private club that decided, for one week, to let everyone in.
The altitude matters. Mexico City sits at over 2,200 metres above sea level. The ball moves faster. The bounces are different. Players who come directly from sea-level events need time to adjust — which is part of why the tournament has become a genuine test of adaptability, not just a formality. Tristan Schoolkate, the Australian who won the week before in San Luis Potosí, arrived in Mexico City as a form player and still had to earn every point. The conditions level the playing field in interesting ways.
The court is named after Rafael “Pelón” Osuna. If you don’t know that name, you should. Osuna was Mexico’s most celebrated tennis player: a doubles champion at Wimbledon in 1960 and at the US Open in 1962 and 1963, an NCAA singles champion, a player who represented his country at the Davis Cup with the kind of consistency and commitment that defined the sport’s amateur era. He died in 1969, at 30 years old, in a plane crash near Monterrey. The Estadio Rafael “Pelón” Osunais not just a name on a building. It’s a statement about what this tournament understands that most tennis events don’t: that history is infrastructure, and that honoring the sport’s local legacy is what makes a tournament feel like it belongs somewhere.
“The court is named after a man who won Wimbledon and died at 30. The stands sell out. The ATP gave it an award. Almost nobody outside Latin America knows it exists.”

The Mexico City Open and What It Says About Tennis in Latin America
The tournament’s full name is the Mexico City Open presentado por Banco BX+. It’s an ATP Challenger 125 — two levels below a Masters 1000, one level below a 500. The prize fund is $225,000, up 12.5 percent from last year. The champion takes home $33,650 and 125 ranking points. By the numbers of the ATP tour, it’s a mid-tier developmental event, the kind of tournament that exists to give players ranked between 80 and 300 in the world competitive clay court matches during a gap in the major calendar.
By the reality of what happens on the ground in Mexico City, it’s something else. The 2025 edition sold out its final rounds. So did 2024, and 2023 before it. The Kids Day — where players spend time with over 120 children aged five to fourteen, running clinics and signing autographs — has become one of the most attended community events of the week. The Fan Fest runs on the Friday of tournament week. Santiago González, Mexico’s most decorated doubles player and a global top-60 doubles specialist, comes back every year to defend, because this tournament means something different on home clay than anything else on his calendar.
That word — home — does a lot of work here. Mexico City isn’t just a convenient host city for an ATP event. It’s a city with a genuine relationship with its tennis culture that the tournament has been smart enough to build on rather than replace. The wildcards are used deliberately to give Mexican players main draw experience they couldn’t otherwise access. Rodrigo Pacheco, the young Yucatan-born player who at world ranking 303 is the best active Mexican singles player, gets to compete in front of a crowd that is genuinely invested in his development. Alex Hernández makes deep runs in doubles. Reyes-Varela shows up and the crowd responds.
The organizers have been explicit about where they want to take this. They’ve already applied to the ATP for an upgrade to Challenger 175. The argument is simple: if you’ve been named the best Challenger in the world, you’ve earned the right to be in a bigger room.

The model that tennis needs to copy
What the Mexico City Open Gets Right That Most Tournaments Don’t
The tennis calendar has a problem that nobody talks about enough: most tournaments exist as logistical entries on a schedule rather than as cultural events. Players show up, play, leave. The city barely notices. The crowd is a polite collection of paying spectators rather than a genuine fan community. The tournament is a product delivered to an audience, not an event that belongs to a place.
The Mexico City Open is a counter-argument to that model. It has spent five years building something that most tournaments with far larger budgets and bigger names in the draw haven’t managed to build: a sense that this tournament is – in some meaningful way – the city’s tournament. That when Rodrigo Pacheco walks onto the Estadio Pelón Osuna and the crowd gets behind him, something real is happening. Not manufactured enthusiasm. Not sponsored atmosphere. The actual thing.
Part of that comes from the venue. Chapultepec is a public park. You can’t manufacture the feeling of a sporting event taking place inside a space that belongs to everyone. The families who come to the park on a Tuesday afternoon and wander past a court where a top-100 doubles player is warming up — that’s not a curated fan experience. That’s a city and a sport in the same room, unselfconsciously.
The other part comes from the local players. Every tournament has wildcards. Most tournaments use them as goodwill gestures that rarely survive the first round. The Mexico City Open has used them as an investment in a fanbase. Pacheco making the main draw isn’t just good for him — it’s good for the tournament, because every Mexican fan who comes to watch him is a fan the sport didn’t have before. The calculus is long-term. Five years in, it’s starting to compound.
“The Mexico City Open has spent five years building what most tournaments with far bigger budgets haven’t: the feeling that this tournament belongs to its city.”

The ATP Challenger Tour is full of tournaments that exist. The Mexico City Open is one of the few that matters. The difference is harder to manufacture than prize money or field depth or broadcast reach. It has to do with a city deciding it wants a tournament and then building the infrastructure — cultural, not just physical — to deserve one.
They named the court after Pelón Osuna. They give wildcards to Mexican kids who don’t need them yet but will. They sold out the final again. And they’re asking the ATP for a bigger room.
Give it to them.
