Clearly he can still play, and staying in the AL and particularly with a team (Detroit) presently starting an oft-injured converted infielder (Carlos Guillen) in left field means he can rotate between starting in LF and DHing more or less whenever he needs.

Comerica is no Yankee Stadium, but it's still friendly to lefty pull hitters: only 330 feet down the RF line and only 365 to the alley.

He's a few million overpaid from the team's standpoint, maybe, and from his standpoint, he cost himself about $6 million total by not taking 2 years/$14 million when the Yankees offered it, but overall, it's not a terrible deal for either side.
