10. Mariah Carey
Carey joins the ranks of terrible celebrity first-pitchers with this attempt from 2011. She attended a game between the Yomiuri Giants and the Rakuten Eagles in the famous Tokyo Dome. As one of the greatest female artists of the 1990s, she was a global superstar. Japanese fans were very excited to watch her throw the first ball of the day in the Nippon Baseball showdown, yet it wasn’t worth the wait.
Ever the diva, Carey looked the part with her giant sunglasses, short skirt, and heels. None of these items were conducive to baseball because she created a failure with her pitching attempt. It was a feeble throw and she was happy to escape from the field. Nobody expected her to throw a 90 mph pitch, but if hers was any slower, it would have gone backward. Stick to the day job, she made untold millions at it.
