The Tigers sealed a deal that keeps Carlos Guillen a cat through 2011.

Guillen is making $5 million this season, the last of a $14 million, three-year deal. He gets $12 million in 2008, $10 million in 2009 and $13 million in each of the final two seasons.

"I'd like to finish my career in Detroit," Guillen said. "I am very happy here. Three years ago we lost 119 games, and now we have a good team with a great future."

Guillens' career track is very interesting. He showed no power before arriving in Detroit, but his OBA started spiking in his last year with the Mariners, and it's been high ever since. He's now parlayed that improved play into a very nice piece of change. Given his age and likely decline, and given what others of similar talents are getting, this is a very good deal for the Tigers.

Tigers fans, was there a particular coach that worked with Guillen to improve his power? Was there ever a reason given for Carlos' surge?
