Not sure about this one. I like the colour scheme, and I could get used to the ball being a weird shape because its meant to be “in flight”. The 2011 isn’t done in a very good font though, and looks a bit separate from everything else – should be a bit more “cartoony”.
The Tigers will keep the 2010 slogan of “Focus on this play, this moment”, which is a bit lame really.

I liked “Be the best for the fans” better.
They should use “Win or lose Tigers pride” as slogan, really…
