Detroit spent Sunday evening narrowing their list of suitors for lefty reliever Justin Wilson, with the potential of a deal Sunday night or Monday morning.

Five teams remain in the mix for Wilson, according to an industry source. The Astros are considered the favorites, according to MLB.com's Mark Feinsand, but the Nationals and Cubs also remain in the hunt according to MLB.com's Phil Rogers and other sources. MLB Network's Ken Rosenthal reported that the Cubs are heavily involved in talks.

Other teams that have been linked at some point to Wilson include the Rockies, Rays, Dodgers, Red Sox, Brewers, Indians and Yankees.
