Reds:
Willie Canate (40) -Venezuelan OF the Reds claimed in the 1992 Rule 5 draft, then traded to Toronto a few weeks later. Appeared only briefly for Toronto.
Thomas Howard (47) -Here's a trivia quiz for those of you who are also Bengal fans: How many Reds and Bengals have shared the same name? Off the top of my head, the Thomas Howards are the only ones, but I bet there's more.
Fred Toney -Famous for his 1917 no-hit duel with Hippo Vaughn. 1918 wasn't so kind to him; he was arrested for draft evasion, and later for violation of the Mann Act.
Charles "Old Hoss" Radbourn -Legendary ironman pitcher with somewhere between 58 and 60 wins in 1884, depending on what source you use. Bothered through his career by leg cramps; the term "charley horse" may have been created in reference to his problem. Finished his career with the 1891 Reds.
Others:
Derek Bell (43) -I don't know quite what to say about Derek; he was a good player, but everything I read about him seems to indicate that he was just not a very nice person.
Jay Bell (46) -Scored the winning run in Game 7 of the 2001 World Series. Broke Ozzie Smith's 13-year run of Gold Glove victories. Also an excellent bunter.
