Ken Rosenthal of FOXSports.com reports that the Tigers are interested in Stephen Drew and Ryan Roberts of the Diamondbacks. The two clubs have discussed scenarios involving one or both players, but it's not clear how advanced talks are. The Tigers already have Jhonny Peralta at shortstop, but Rosenthal speculates that the D-Backs could ask for him as part of a trade, as his contract includes a $6 million club option for next year. Roberts could slide in at second base, where the Tigers have a clear need.
