Charlie Sheen is one of the most famous actors in Hollywood, but he is also one of the biggest and most knowledgable baseball fans.
The star is most well known for his previous roles in Two and a Half Men and the movie Wall Street, but it's his love of the Cincinnati Reds that gets him excited the most.
Some celebrity fans are not exactly the cream of the crop when it comes to baseball intelligence, however, that's not Sheen. He's on another planet all to himself, as we already know.
He appeared on Baseball tonight Sunday night and delighted the studio team with his knowledge of general baseball, and particularly his Cincinnati Reds knowledge.
It's clear the Anger Management star was there to answer real baseball questions and he had certainly done his homework.
After getting asked about the pitchers match-up of the Reds' Mike Leake against the Cardinals' Adam Wainwright.
Sheen commented that Leake has been pitching well without receiving offensive report, and he added, "They say pitching and defense win a championship, but you've got to throw in a little offense sometimes."
