In the world of tennis, few stories resonate with the bittersweet ache of "what could have been" quite like that of Juan Martin del Potro. The towering Argentine, known for his thunderous serve and explosive forehand, captured the sport's imagination with a stunning US Open victory in 2009, defeating the legendary Roger Federer. That win signaled the arrival of a major new force, a player with the raw power and skill to challenge the era's dominant 'Big Four'.

Yet, as tennis legend Jim Courier recently reflected, Del Potro's career trajectory was dramatically altered by persistent injuries. "I think he would have altered tennis history had he been able to remain healthy," Courier stated on the Tennis Channel. "He broke through with that US Open win... and then his wrist starts to bark. And from there it’s just comeback after comeback."

This cycle of injury and resilience defined Del Potro's journey. Despite the physical setbacks that prevented him from adding more Grand Slam titles to his name, his talent never dimmed. He fought his way back to world number three, led Argentina to a historic Davis Cup triumph in 2016, and powered his way to another US Open final in 2018. His ability to compete at the pinnacle of the sport, even after multiple surgeries, earned him immense respect from peers and fans alike.

Ultimately, a devastating knee injury suffered at Queen's Club in 2018 led to another long absence, and Del Potro announced his retirement in 2025. His career stands as a powerful testament to both supreme talent and incredible fortitude, leaving us to forever wonder just how high his ceiling might have been in a fully healthy body. For athletes and fans, his story is a poignant reminder of the fragile line between peak performance and physical limitation.
