Bryce Harper turned heads with a home run derby that has already exploded online.

Harper, the Phillies superstar and two-time National League MVP, had a hilarious offseason moment when he appeared in a head-to-head batting contest with social media sensation “Big Justice” on the YouTube channel “MrBeast.” “ competed for prize money of 100,000 US dollars. The video featured one-on-one battles between non-athletes and sports superstars like Harper, seven-time Super Bowl champion quarterback Tom Brady, Olympic gold medalist and world sprint champion Noah Lyles, two-time major golfer Bryson DeChambeau and perhaps the greatest football player of all Times in Cristiano Ronaldo.

The baseball segment of the video was a high-profile showdown that featured a 10-swing swing-off style home run derby at First Horizon Park in Nashville, Tennessee. Harper has been one of the sport’s most recognizable faces since he was a teenager, and 11-year-old Big Justice has become one of the internet’s breakout stars this year.

He and his father, AJ Befumo, have over 2.4 million followers on their TikTok profile “AJ & Big Justice” and create videos focused on food reviews, giving each item a “boom” or “doom” rating and about chicken casseroles talking about Costco and “Double Chunk Chocolate Cookies” and just “bringing the boom.” The duo’s song “We Bring the BOOM!” has also gone viral, as its remix, which features a verse from their frequent collaborator “The Rizzler,” reached over 1.2 million YouTube views.

If this all sounds ridiculous, that’s because it is. But this type of content has skyrocketed online, leading to huge success and exposure for AJ and Big Justice. They recently appeared on “The Tonight Show Starring Jimmy Fallon” and had a professional wrestling gig on All Elite Wrestling. Her newfound fame also led to Big Justice, a youth player on the Boca Beach Boys team in Boca Raton, Florida, competing against Harper in the Home Run Derby.

Harper provided the momentum with four home runs in 10 swings, but ultimately left Big Justice to be the undoing, who hit five home runs over a 201.5-foot fence that leveled the playing field between the two. Harper seemed to enjoy the fun and absurdity of it all. “Bring the boom, baby!” he shouted to the young right-hander at some point between swings.

Big Justice hit his fifth home run in his ninth at-bat to win the prize money – the money would have been donated to a charity of Harper’s choice if he had hit Big Justice – and the TikTok star fired his bat in celebration. He rounded the bases before being greeted at home plate by AJ, “Momma Justice,” and his sister Ashley.

The video, featuring Harper and the other Titanic sports characters, was well received after it was uploaded on Saturday and quickly became the most popular video on YouTube with over 36 million views and counting.
