Carlos Guillen was hoping not to talk about a new contract during the regular season. He won't even have to talk about it through the end of Spring Training. On the same day the Tigers announced they'll be without Kenny Rogers' services until July, they also announced they'll have Guillen's services through 2011. The star shortstop signed a four-year contract Friday worth $48 million, ending the free-agent speculation and keeping a critical member of the Tigers in Detroit. "We've very thrilled to reach this agreement," president/CEO/general manager Dave Dombrowski said. "He's one of our core players who has done so much for us, not only on the field but off the field. We're very pleased to have done this."
