Carlos Alcaraz watches younger brother Jaime’s winning debut in Madrid under-16s

Carlos Alcaraz returned to the Caja Magica this week—this time as a spectator—proudly watching his younger brother Jaime make a winning debut at the Madrid Open’s under-16s tournament.

The seven-time Grand Slam champion was joined by his parents in the stands on Court 7, with Flavio Cobolli also in attendance. A friend of the Alcaraz family, Cobolli regularly visits and trains with Alcaraz during the offseason.

They were all seen cheering and applauding as 14-year-old Jaime notched his first victory in Madrid, a 6-3, 6-3 win over fellow Spaniard Pol Mas Tabuena.

A nice detail: Jaime taking the court wearing Nike’s Vapor 12 “Carlos Alcaraz” shoes, a model designed in collaboration with his older brother.

Afterward, Carlos shared a photo with his brother alongside Jaime's coach, Ramon Abenza Sanchez, on Instagram Stories with the caption, "Proud."

Jaime is the youngest of the four Alcaraz brothers, turning 15 in June. He trains at the Carlos Alcaraz Academy in Murcia—his father’s academy, where his older brother also learned the game. Earlier this year, he went viral after winning the under-15 division event at ATP Challenger in Murcia, sealing the title with an impressive match point.

On Thursday, Jaime also became the first Alcaraz to win a match at Caja Magica in two years. Older brother Carlos has been sidelined with injury and missed the Mutua Madrid Open for a second consecutive year.

Carlos was seen wearing a rigid splint on his right wrist on Thursday. He suffered the injury in Barcelona, where he was forced to retire mid tournament, and later announced he would also miss Rome and Roland Garros—two major events where he had been the defending champion.

Earlier in the clay season, Alcaraz started strong with run to the final in Monte Carlo, where he fell to rival Jannik Sinner. The defeat saw Sinner leapfrog the Spaniard to take the ATP’s No. 1 ranking.
