NBA star Jimmy Butler WINS a point off reigning US Open champion and World No. 1 Carlos Alcaraz after debuting as a ball boy

Miami Heat All-NBA forward Jimmy Butler became the center of attention at Louis Armstrong Stadium when he hilariously ran onto the field and made his debut as a ball boy on Wednesday night.

Butler also didn’t stay on the sidelines as he jokingly defeated world No. 1 and defending US Open champion Carlos Alcaraz.

He and Alcaraz played out a point as the Spaniard mocked as he rallied with the NBA star at about half the pace of his usual opponents.

And while Alcaraz was obviously taking it easy against Butler, the Miami Heat player still walked away with the win thanks to a quick forehand hit, for which the Grand Slam winner did an exaggerated stretch.

Butler, along with Alcaraz, American tennis star Frances Tiafoe and singer Sebastián Yatra, picked up a racket as part of a charity event in Flushing Meadows for the war in Ukraine.

Butler also played a doubles match with Frances Tiafoe against Alcaraz and Sebastian Yatra

The US Open’s ‘Stars of the Open’ event has raised $320,000 for humanitarian aid in Ukraine.

Other just-for-fun exhibits at Stars of the Open at Louis Armstrong Stadium included John McEnroe, Gabriela Sabatini, Jessica Pegula, Matteo Berrettini, Elena Svitolina, Gael Monfils, Chris Eubanks, and Jennifer Brady.

Fans of the Heat will surely be glad that Butler’s adventure on the tennis court was all about laughs, not a serious game, to avoid injury ahead of the upcoming NBA season.

Butler led Miami on a Cinderella-esque run through the NBA Finals before eventually losing to the Denver Nuggets.

Hooper, 33, is also a well-documented tennis fan and is friends with American stars Tiafoe and Coco Gauff.

The US Open starts on Monday and Alcaraz wants to defend his title after his victory at Wimbledon earlier this year.
