Miami, 2023. The air was thick, electric, and heavy with the hopes of two nations. On the mound, Edwin Díaz was locked in a cinematic 10-pitch duel with Teoscar Hernández. With a wicked inside slider that defied physics, Díaz froze Hernández, sending Team Puerto Rico to the quarterfinals and the stadium into a delirious frenzy.
But in the blink of an eye, the euphoria curdled. As a sea of teammates swarmed the mound in celebration, Díaz collapsed, clutching his knee. What should have been a career-defining highlight instantly transformed into a nightmare: a torn patellar tendon that would sideline the world’s most dominant closer for the entire 2023 MLB season.
Three years later, the “fluke” hasn’t fueled fear—it has fueled a homecoming. With Puerto Rico set to host Pool A in San Juan starting March 6, Díaz didn’t hesitate to return.
“That was an easy decision,” Díaz said. “It’ll be my first time playing in front of my people in Puerto Rico, so that was an easy ‘yes’ when I knew the WBC was going to be there.”
The Insurance Wall and the “WBC Curse”
While Díaz’s heart is set on San Juan, the road to the WBC has become a minefield for MLB’s elite. The “Díaz Incident” serves as a permanent cautionary tale for front offices. Consequently, securing clearance has become a grueling uphill battle.
Puerto Rican icons Francisco Lindor and Carlos Correa, despite their desperate desire to represent their island, are notably absent from the roster after failing to secure the necessary insurance. It is the silent reality of the sport: MLB managers are holding their breath, watching multi-million dollar investments compete at 100% intensity just weeks before Opening Day.

A History of Hard Hits
The “WBC Curse” is more than just a superstition; the ledger of injuries is long:
-
Jose Altuve (2023): A fractured thumb on a hit-by-pitch cost him 43 games and disrupted a decade-long streak of durability.
-
Miguel Cabrera (2017): A back injury suffered during the tournament led to the worst offensive season of his legendary career.
-
The Pitching Toll: In 2023, both Shohei Ohtani and Sandy Alcántara pitched in the WBC and ended the year undergoing Tommy John surgery. While causality is debated, the “ramping up” process in March remains a terrifying prospect for pitching coaches.
The “Masterclass” in Collaboration
To combat these risks, the 2026 tournament is seeing unprecedented collaboration between MLB clubs and national teams. Take the case of Mason Miller, the San Diego Padres’ fireballer.
Weeks before the first pitch, Padres pitching coach Ruben Niebla was in a “continuous loop” with Team USA’s Andy Pettitte. They meticulously mapped out Miller’s usage to ensure his build-up for the 162-game grind remained on track.
Cubs manager Craig Counsell notes that the responsibility ultimately falls on the players to “own” their preparation. “You don’t necessarily have the whole organization structuring everything quite the way they would if you were in your team’s camp,” Counsell explained.
The Dodgers’ Gamble
No team is leaning into the risk quite like the Los Angeles Dodgers. The defending World Series champions are sending a small army to the tournament, including:
-
Will Smith (USA)

-
Shohei Ohtani (Japan – Hitting only)
-
Yoshinobu Yamamoto (Japan)
Yamamoto, the 2025 World Series MVP, is Japan’s undisputed ace. He arrives fresh off a postseason where he threw 526 high-leverage pitches. Despite the heavy workload, Dodgers President Andrew Friedman remains supportive.
“It is impossible to tell those guys to dial it back in any way, and nor would I do that,” Friedman said.
The Safety Net: WBC Pitching Rules
To protect these arms, the tournament enforces strict limitations:
-
Pitch Limits: 65 pitches (Round 1), 80 (Round 2), 95 (Championship).
-
Mandatory Rest: 30+ pitches require 1 day off; 50+ pitches require 4 days off.
-
Reliever Cap: No pitcher can throw three days in a row.
The Ultimate Question: WBC or World Series?
For the players, the risk is a small price to pay for the chance to wear their country’s name across their chest. Before leaving for camp, Edwin Díaz was asked which title carries more weight.
“I haven’t had the chance to play in the World Series, but I heard people say it’s about the same,” Díaz said with a smile. “So when I have a chance to play in the World Series, I’ll tell you guys how it feels.”
For now, Díaz and the rest of the world’s best are ready to roll the dice once more.
