"First, I want to say congrats to all the other nominees," Davis said during her acceptance speech. "And I just want to thank my parents and my coach and my teammates for helping me be the person I am today."
It has been a whirlwind year of success for Davis. In August, she became the fourth American girl and the 18th overall to play in the Little League World Series. She is the first African-American girl to ever play in the tournament.
Playing for the Taney Dragons at the age of 13, Davis was also the sixth girl in LLWS history to record a hit. On Aug. 15, she became the first girl in the tournament's history to pitch a shutout. From that point on, Davis has been a star.
Davis donated her jersey to the Hall of Fame. She was the first Little Leaguer to ever appear on the cover of Sports Illustrated, which she did on Aug. 25. She was mentioned in Time magazine and was the subject of "I Throw Like a Girl," a documentary directed by Spike Lee.
Davis threw out the ceremonial first pitch before Game 4 of the World Series in San Francisco. In December, only a few months after bursting on to the national scene, she was named the Associated Press Female Athlete of the Year.
In February, she took part in the NBA's All-Star Celebrity Game. This summer, she toured with the Anderson Monarchs on a 23-day tour to pay tribute to Jackie Robinson, the Negro Leagues and the civil rights movement.
The competition Davis beat for the ESPY Award speaks to her success. Also nominated were New York Giants wide receiver Odell Beckham Jr., Ohio State Buckeyes quarterback Cardale Jones and PGA Tour golfer Jordan Spieth.
Angels superstar Mike Trout, who unanimously won last year's American League MVP Award and took home All-Star Game MVP honors on Tuesday night, received yet another award at the ESPYs.
