Um.... Zito: 86-53, 3.50 ERA, 1.22 WHIP, 461 BB, 945 K's, 1209 IP Williams: 23-22, 3.92 ERA, 1.31 WHIP, 142 BB, 238 K's, 383 IP I'd say yes, Zito is better. That said, Jerome is 3 years younger and nearly $5.5 million cheaper (and not a free agent next year) He'll actually be more than $8 million cheaper next season.
