Only 10 AL rookies have over 300 AB and of them only 4 have have an ops above .700.
Hideki Yamamoto has my vote already. He leads AL rookies in HR, R, and RBI.
Worth mentioning is Al Nixon who has under 300 AB and 55 fewer than Yamamoto. He only has 2 fewer HR and an OPS over .900. By season's end it may be worth discussing.
Now that I have done the offense I have reconsidered what I said about the pitchers. I expect 2 of them to be nominated.
