WATCH: Mo'ne Davis Strikes Out Jimmy Fallon

Little League pitcher Mo’ne Davis appeared on “The Tonight Show” Friday night, and bet host Jimmy Fallon a cheesesteak that she could strike him out, wiffle ball-style.

Fallon owes her a cheesesteak.

Davis pitched to her longtime catcher, Scott Bandura -- as Fallon pointed out, the two have been playing together since they were 7 years old.

Mo’ne Davis and the Taney Dragons this summer finished third in the Little League World Series. Davis became the first Little League player ever to grace the cover of Sports Illustrated.

As Fallon said at the end of the segment, “Remember her name.”
