First of all, thanks to siggian for the previous post.  Here are some more for the AL East:

Derek Jeter

He has Twitter,

But doesn't say how

To move like cow.

A.J. Burnett

Smart like bullet.

He's a dumb-mule,

'The Yankee Stool'.

Boston Red Sox

Need asterisks,

They weren't clean

It's 1918.

New York Yankees

Stained by PED's,

Of Stolen moments

and half-mast pennants.

Alex Rodriguez

No matter what he does,

Ain't got nothin'

on Ben Johnson.

Brett Lawrie

Brewers be sorry

We'll be smitten

It is written.
