The Tigers and Miguel Cabrera made his new contract official today:

Cabrera's agent, Fernando Cuza, confirmed the contract is worth $153.2 million, which includes the one-year contract Cabrera had agreed to previously.

Asked his long-term career goals, Cabrera said, "The World Series."

I asked J.C. Bradbury and Mitchel Litchman in an email to clarify their positions on Cabrera's salary, and Mitchel now says he made a mistake in his calculations:

I think I screwed up in my post. When I looked at my database, I looked at the column for dollar value and not RAA (runs above average). His dollar value was 19 (million) in my chart and I thought I was looking at +19 runs above average.

So he is indeed worth 4-5 WAR, which is worth around 21.5 mil per season, based on 4.5mm per marginal win (plus minimum salary of .38mm).

An honest mistake. It's a very good deal for the Tigers.
