Miguel Cabrera and the Tigers are closing in on an extension for the superstar slugger that will likely make him a Tiger for life, sources told CBSSports.com. There will still need to be a physical before anything is finalized, but Cabrera has a remarkable record for staying healthy. The two-time defending AL MVP and the Tigers have been working on the deal in the last few days, and word is they are close to finalizing the agreement. Cabrera, 30, has been playing on a $152-million, eight-year contract that is due to expire after the 2015 season. People close to him say he loves being a Tiger, and suggested he's willing to take less than top free-agent dollar to stay in Detroit. The terms of a new deal aren't known yet. The Tigers traded Prince Fielder in the winter partly to free up money to sign Cabrera and Cy Young winner Max Scherzer to long-term deals. The Tigers announced recently they were unable to extend Scherzer. They offered the righthander $144 million over six years, as Foxsports.com originally reported.
