Even when he's not on the court, Carlos Alcaraz can't stay away from the game. The world number one was forced to withdraw from the Madrid Open due to a wrist injury, but that didn't stop him from showing up at the Caja Mágica on quarter-final day—this time as a proud older brother rather than a title contender.

While the crowd's attention was on stars like Casper Ruud and Alexander Zverev, Alcaraz had his eyes fixed on a different court entirely. He was there to watch his 14-year-old brother, Jaime Alcaraz, compete in the Madrid Open U-16 tournament. And the younger Alcaraz didn't disappoint, delivering a performance that would make any sibling beam with pride.

Jaime cruised to a 6-3, 6-3 victory over fellow Spaniard Pol Mas Tabuena, even pulling off a deft dropshot that echoed his brother's signature style. After the match, Carlos kept it simple on Instagram with a one-word post: "Proud."

But behind the heartwarming family moment lies a growing concern for Alcaraz's season. The two-time Grand Slam champion is now set to miss the remainder of the clay-court swing, including Rome and Roland Garros, where he would have been defending a staggering 3,000 ranking points. That opens a golden opportunity for Jannik Sinner to extend his lead in the race for world number one.

Alcaraz is aiming for a return during the grass season, with Queen's Club and Wimbledon firmly in his sights. But those tournaments carry their own weight—he won Queen's last year and finished runner-up at Wimbledon, meaning another 1,800 points could slip away if he's not ready. Novak Djokovic and Alexander Zverev are lurking, ready to close the gap.

It's been a rollercoaster year for the Spanish sensation. He started 2024 on fire, completing his Career Grand Slam at the Australian Open and adding the Qatar Open title. But form has dipped since a semi-final loss at Indian Wells, and now injury has brought his momentum to a halt.

For now, Alcaraz is trading his racket for a seat in the stands. But if his brother's performance is any indication, the Alcaraz name is in good hands—on and off the court.
