Just came across a stat that made me do a double-take.

Justin Smoak started the year with the Rangers and drew 38 walks in 275 PA. Which works out to a very respectable 13.8%.
He gets traded to the Mariners and draws exactly 1 walk in 81 PA.
This equates to a miserable 1.2%.

For comparison, Smoak's 13.8% would nestle right between Pujols at 13.9% and Votto at 13.7% That is some pretty serious walking.
OTOH, Smoak's 1.2% would be worst among players with 350 or more PA on the year.

That doesn't even seem possible to me.
