Walker Freeman made a significant impact in the United States men’s national team’s opening match of the World Cup, starting in the 4-1 victory over Paraguay. The 21-year-old defender, once a reserve player for Orlando City in MLS Next Pro and initially outside the national team’s plans, has quickly established himself as a key component under coach Mauricio Pochettino.

Freeman’s rise to a World Cup starting position is notable given his unconventional path. A decade ago, he transitioned from American football to soccer, a move that has now culminated in his first World Cup appearance. Since being called up by Pochettino last year, Freeman has become a fixture in the team, appearing in 17 consecutive matches. At 21, he is the ninth-youngest American to start a World Cup game and part of the second-youngest U.S. roster fielded at the tournament in over three decades.

Pochettino’s selection criteria emphasize players’ suitability for his tactical system rather than their club status. Freeman’s versatility in defense, able to operate across multiple formations, aligns with the coach’s strategic approach. This adaptability has allowed him to flourish alongside other young talents such as Giovanni Reyna and Chris Richards Balogun, the latter of whom scored twice in the opening match—marking the first time an American has done so since nearly a century ago.

Freeman has spoken openly about the adversity he has faced, crediting it with strengthening his resolve and performance on the field. He expresses no regrets about his decision to pursue soccer instead of football, a path supported by his father, who regards his World Cup participation as a greater accomplishment than winning a Super Bowl.

As the U.S. team advances in the tournament, Freeman’s development and resilience exemplify the youthful energy and tactical flexibility that have become hallmarks of the current squad under Pochettino’s guidance.
