According to CBS Sports' Danny Knobler, the Tigers have shown interest recently in Roy Oswalt. The Red Sox are thought to be leading the charge for Oswalt at this point, but Detroit could make things interesting. The 34-year-old right-hnader posted a 3.69 ERA and 1.34 WHIP in 23 starts last season for the Phillies. He's said to be in search of a one-year deal worth around $8-$10 million.
