Joba's brief minor league record is just as otherworldly as his numbers as a relief pitcher, while Marmol was merely "pretty great" as a minor league starter. However, if you look at how Marmol finished his minor league years as a starter(2006-2007), it's closer. Joba (40 IP at A+, 40.1 at AA, 8 at AAA) 88.1 IP, 1.01 WHIP, 13.76 K/9, 2.75 BB/9, 5.00 K/BB, 0.41 HR/9 Marmol(58 IP at AA, 44 at AAA) 112 IP, 1.01 WHIP, 9.32 K/9, 3.05 BB/9, 3.05 K/BB, 0.40 HR/9 The strikeout and walk numbers are better for Joba, but on the other hand half of those innings were against High A competition, so it's probably closer to a wash than it appears.
