6. Ty Cobb
Can virulent racists be badass? This one's gonna 'cause some controversy, but you can't list the most badass baseball players of all time and not include Ty Cobb. His playing style was called "daring to the point of dementia" and the undersized Cobb tried every trick (legal and not) in the book to win. He spiked opponents, fought spectators, and, in his own words, "tried plays that looked recklessly daring." Reckless daring? That's badass no matter how you cut it.
