Though Joao Fonseca lost matches to Carlos Alcaraz and Jannik Sinner this month, the 19-year-old Brazilian's short-term disappointment could pave the way to a new level of success on the ATP Tour. Alcaraz, who also struggled early in his career against Rafael Nadal, believes Fonseca's tough losses will provide valuable lessons to help him improve and climb the rankings.

Why it matters

Fonseca's matches against the world's top players, despite the losses, demonstrate his potential and ability to compete at the highest level. Alcaraz's own experience of being "destroyed" by Nadal early on, only to later beat him, shows how these kinds of challenges can ultimately lead to growth and success.

The details

Fonseca fell 6-4, 6-4 to Alcaraz on Friday at the Miami Open, less than two weeks after dropping a 7-6(6), 7-6(4) decision to Sinner in the Indian Wells fourth round. While Alcaraz was happy with his composure under pressure, he knows an even tougher test may await in his second showdown with Fonseca. Alcaraz recalled his own introduction to the game's elite against Rafael Nadal, where he lost 6-1, 6-2 on the red clay, but went on to score his first win against Nadal a year later.

What they’re saying

“For him, playing toe to toe with us, I think he and his team are going to get great feedback to know what he should improve in the future. I think he has everything, great shots, a lot of things to improve, but for sure he's going to do it. Back-to-back tournaments playing the No. 1 and No. 2 in the world, I think it's going to be really helpful for him.”

“I do remember when I played Rafael Nadal for the first time, and I do remember how good that match was for me, even though I was destroyed.”
