Little League star Mo'Ne Davis goes to bat for her Twitter tormentor

Mo'Ne Davis, the teenage pitching phenom who took Little League by storm and has inspired a Disney movie, went to bat Monday for a college star who got kicked off his team for a nasty tweet about her.

The 13-year-old, who was named Associated Press Female Athlete of the Year for 2014, reportedly wrote to Bloomsburg University in Pennsylvania and asked the school to reconsider its decision to eject Joey Casselberry, who sent out a tweet calling Davis a "slut" on Friday and ridiculing the idea of a movie about the girl, who exploded onto the national stage with her performance during last summer’s Little League World Series for the Taney Dragons of Philadelphia.

But Mo'Ne showed she has a heart as golden as her right arm, sending an e-mail to Bloomsburg President David Soltz asking that Casselberry be given a second strike.

Mo'Ne's email to Bloomsburg University:

Dear Dr. Soltz,

I am writing about the Tweet sent out by your baseball player, Joey Casselberry, and his dismissal from the team because of it. While I admit I was pretty hurt when I read his comments, I felt sad that he was dismissed from the team. As many people know, my dream is to play college basketball and maybe even professionally. I know how much hard work and dedication it will take to get there, and to have that dream taken away would be heartbreaking.  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. I hope you will give him a second chance and allow him to play.

Thanks.

Mo’ne Davis

"He made one dumb mistake," Mo'Ne wrote in an e-mail to Soltz. "I’m sure he would go back and change it if he could."

For his part, Casselberry, a sophomore first baseman and one of Bloomsburg's top sluggers, has apologized, but the school gave him the boot.

“Bloomsburg University is deeply saddened by what was written about Mo'ne Davis by one of our student-athletes," the school said in a statement. "His words do not represent us. We take matters very seriously; addressed the issue with the student-athlete (who has been dismissed from the team), coach and the team.”

“An example that one stupid tweet can ruin someone's life and I couldn't be more sorry about my actions last night."

Even Mo'Ne's e-mail did not sway the school, although Bloomsburg spokesman Tom McGuire said officials respect Davis' opinion and maturity.

"Her request demonstrates the type of person she is, her level of maturity and the empathy that her family and coach teach her," the school told FoxNews.com in a statement. "Bloomsburg University stands firm on our decision; however, his consequences will be reviewed as is common in disciplinary actions like this."

Casselberry deleted his Twitter account, but not before he apologized for his foul comment.

“An example that one stupid tweet can ruin someone's life and I couldn't be more sorry about my actions last night," he wrote. "I please ask you to forgive me and truly understand that I am in no way shape or form a sexist and I am a huge fan of Mo'ne. She was quite an inspiration."

Mo'Ne's mother, Lakeisha McLean, declined to comment on the matter when reached by FoxNews.com.
