Re: Hall of Fame worthy? ....
According to Baseball Reference, the two most similiar pitchers to Chris Carpenter are Dennis Leonard and Freddie Garcia, neither of whom has ever been accused of being a HOF'er.
Carpenter had some decent years (winning more than 17 games once in his career), and was a tough competitor to be sure, but he's no where close to HOF consideration.
Even if he was borderline, he won'r stand a chance.
Borderline cases like Tony Perez get in because they were much loved by teammates and opponents alike. CHris Carpenter has been generally hated throughout baseball. Respected by his teammates for his skill and competitive nature, even they didn't particularly like him.
