The list features 50 Cent, but it also includes other artists. "To prove that 50 Cent isn't the only musician to have had troubles on the mound, here are five other less-than-awe-inspiring first pitches at baseball games," Billboard says.
Mariah Carey's pitch, which landed nearly in front of her, made the list.
Another pitch that also made this list was Justin Bieber's, which went off to the right side of the catcher.
Following his pitch, 50 Cent said he is not a ball player. Instead, he said, he's a hustler.
