4:34pm: The Indians have joined the Tigers in the pursuit of Marquis, tweets ESPN's Jim Bowden. The two division rivals appear to be chasing many of the same starting pitchers. The Nationals are asking a lot, as they reportedly want teams to take on Marquis' remaining $2.5MM and surrender a prospect.
12:21am: The Tigers are discussing a trade for Jason Marquis, according to Ken Rosenthal and Jon Paul Morosi of FOX Sports. Detroit GM Dave Dombrowski has been looking for starting pitching this month and has had interest in Marquis.
Though the Tigers have pursued others, including Hiroki Kuroda and Jeremy Guthrie, they're not sure that Kuroda would accept a deal to Detroit and appear to have struggled to reach a deal with the Orioles for Guthrie. Tigers checked in on Doug Fister, but they were turned off by the Mariners' asking price. They contacted the Rockies about Ubaldo Jimenez as well.
