From Miami to Mazatlán: ISPS’s Rising Impact on International Slow Pitch Softball

From Sunshine State Roots to Global Softball Hotspots

If you've followed the energy around International Slow Pitch Softball (ISPS) over the past decade, you already know: powerful things can grow from humble beginnings. What started in Miami in 2008 as “Florida Adult Softball” was a heartfelt venture—born of love for the game and inspired by the memory of fallen hero PFC Marius L. Ferrero.

Those early years saw ISPS rapidly connect with local athletes, transforming city parks and neighborhood fields into a network of competition and camaraderie that soon stretched beyond Miami-Dade and Broward. The passion was contagious, and it didn’t take long for word to spread out of state.

But the true game-changer? Puerto Rico. When softball leaders from the island joined in, ISPS leadership realized they needed a bigger stage. The organization went global, inviting new players, directors, and fans from all corners—and rebranded to the International Slow Pitch Softball (ISPS) you know today.

New Destinations, New Dreams: Puerto Rico & Mazatlán Take the Stage

Puerto Rico: Island Pride, Worldwide Competition

Few places boast the fierce community spirit of Puerto Rico. Since joining ISPS’s expanding family, the island has become a magnet for regional qualifiers, all-star showcases, and championship tournaments. Puerto Rican teams are known for their electric style—big bats, fast gloves, and a sound track that never stops.

ISPS events in Puerto Rico have shaken up the competitive landscape, introducing fresh rivalries and partnerships. Frequent collaborations with local federations have unlocked opportunities for youth players, women’s squads, and senior leagues, all under the bright Caribbean sun.

Mazatlán: From Vacation Paradise to International Softball Capital

Flip the map and fly west, and you’ll find another epicenter: Mazatlán, Mexico. Just steps from the Pacific coast, Mazatlán has made a name as one of ISPS’s most exciting international venues. Thousands now flock here for the annual Efrén Fierros International Tournament, turning the city’s diamonds into the heart of the slow pitch universe.

Why Mazatlán? Besides the unbeatable weather and beachfront backdrop, the city has gone all-in to support international competition. First-class facilities, seamless logistics, and a local softball community that throws a welcome party for every player. Here, every inning echoes with energy.

More Than a Game: How ISPS Fosters Global Softball Family

Building a Worldwide Network

First and foremost, ISPS is about connection. Over the past five years, the number of registered teams in ISPS events has exploded by over 40%. ISPS now operates everywhere—from North and Central America, to the Caribbean, Europe, South America, Asia, Africa, and the Middle East. Players from Miami to Mazatlán, Puerto Rico to Panama, and far beyond are part of the same lineup.

This network isn’t just for elite athletes—ISPS champions accessibility, ensuring athletes of all ages and skill levels can find a spot on the field. Whether you’re a weekend slugger or a national standout, there’s a tournament—and a community—waiting for you.

Tournaments With a Difference

ISPS events are designed for true fans of the game. We’re talking official ISPS-branded championships, global “Worlds,” regional Opens, and creative one-offs like the Winter World Championships and Hispanic World Series. Each tournament is more than just a bracket—it’s a festival.

Players rave about the attention to detail: professional umpires, premium equipment, team swag, and full safety services, including on-site paramedics. But the real magic is in the vibe—teams trading culture, friendships forged under the lights, and the roar of the crowd after a game-winning double.

Says ISPS Commissioner Manuel T. Ferrero III:

“Every pitch, every hit, and every catch in Mazatlán tells a story of passion and perseverance. This tournament is not just a series of games; it’s a beacon for the spirit of slow-pitch softball.”

Spotlight: The Efrén Fierros International Tournament in Mazatlán

When it comes to international slow pitch, the Efrén Fierros event is a showstopper. Teams from across the Americas descend on Mazatlán, representing Mexico, the United States, Puerto Rico, and more. You hear everything on the field—English, Spanish, even a little Spanglish—but the language of hard-fought softball needs no translation.

The event has set the gold standard for international tourneys:

• Location: Stunning Pacific coast facilities with top-tier fields.
• Organization: Collective effort from local officials, city partners, and ISPS’s seasoned event staff.
• Inclusivity: Men's, Women’s, Coed & Senior divisions all represented.
• Cultural Flavor: Think mariachi strolls between innings, local cuisine stands, and post-game fiestas.
• Professionalism: Full umpire crews, quality equipment, prizes, and ongoing medical support.

The Mazatlán experience is a blueprint for ISPS expansion worldwide—a model of how sport can bring people together across borders, backgrounds, and belief.

Opportunities for All: How ISPS Changes Lives

For players, coaches, and fans, joining an ISPS event is about more than just stats and standings. It’s about personal growth, new friendships, and representing something bigger than yourself. Puerto Rican teams have gone from backyard scrimmages to international final four appearances. Mazatlán locals now have a path to face off against top-tier talent from far beyond Mexico. Dreams get bigger. Horizons expand.
