A college baseball player was quickly dismissed from his team after calling Little League pitching sensation Mo'ne Davis a "slut" on Twitter. 

The offensive tweet came from Joey Casselberry, a first baseman at Bloomsburg University in Pennsylvania. Casselberry wrote, "Disney is making a movie about Mo'ne Davis? WHAT A JOKE. That slut got rocked by Nevada," then eventually deactivated his account.

The school announced the next day that Casselberry had been removed from the team. 

But Casselberry, who apologized and called it "an example that one stupid tweet can ruin someone's life," found himself with an unlikely supporter: the 13-year-old Davis. 

She actually emailed the school Sunday and asked that they reconsider the decision to boot Casselberry from the team. 

“I am sure Joey Casselberry has worked very hard to get where he is and dreams of playing in the major leagues. For this reason, I'm asking you to please allow him back on the team so that he can continue to chase his dream. He made one dumb mistake. I'm sure he would go back and change it if he could. We all make mistakes and deserve to be forgiven," she wrote.

TMZ reported that the university praised Davis for her maturity about the tweet, but are "standing firm" on the decision to dismiss Casselberry from the team.

Davis captivated the nation last summer with her amazing pitching at the Little League World Series, as she used her dominating curveball to become the first-ever female pitcher to win a game in the tournament.

The Philadelphia resident has since given her jersey to the Baseball Hall of Fame, released a book about her life, and was named AP Female Athlete of the Year. She will also be the subject of a Disney Channel movie, "Throw Like Mo."
