Blanton's era is 3.89 for Oakland. But looking into his numbers, he is averaging almost 7 innings per start, and has given up only 2 runs in 4 of those starts and 3 in one other. He's definitely more of a #3 or #4 pitcher, but would be a nice compliment. His era would probably be more in the middle 3's in the NL.
Just creating conversation.
