It doesn't matter what the surface is, Jimmy Butler can't help but score points.

At a charity exhibition match leading up to the US Open on Wednesday night, the Miami Heat star was serving as an honorary ball boy in a match between Carlos Alcaraz and Frances Tiafoe. At one point, Butler asked Tiafoe if he could step in to receive a serve, and Tiafoe obliged.

Alcaraz's serves normally top 120 mph, but he offered up a distinctly gentler one for Butler. Butler returned it, and the two exchanged volleys until this happened:

Heat star Jimmy Butler has some fun at US Open qualifiers, joining Frances Tiafoe's ball crew and then entering the match to win a point vs. Carlos Alcaraz.

There's a reason they call him "Jimmy Buckets."

The US Open main draw is airing on the ESPN family of networks from Monday through Sept. 10 at the USTA Billie Jean King National Tennis Center in New York.
