Lackey, but Aviles is a close 2nd.
I cannot take Aviles cocking his head to the side in complete disbelief everytime he makes an out or watches a called strike.
And I cannot take Lackey throwing his arms up in the air everytime a player doesn't make a diving catch.
Crawford would be really far down on the list for me. Putting him, Ells, and Pedroia in the top 3 slots is really fun to watch with Ortiz, Gonzalez, and Middlebrooks hitting behind him.
