6:13pm: In addition to the Cubs, the Diamondbacks are also interested in Stewart, tweets Jon Heyman of SI. The 26-year-old is very likely to go somewhere, according to Heyman.
FRIDAY: The Rockies think highly enough of Stewart that they would not consider trading him for DeWitt, according to Renck.
11:39am: The Rockies have already moved Ty Wigginton and Chris Iannetta this offseason, and they're reportedly open to dealing Ian Stewart and Huston Street as well. Troy Renck of The Denver Post reports that Colorado has asked the Cubs for Blake DeWitt in exchange for Stewart, but talks between the two clubs have since cooled.
DeWitt, 26, is a left-handed bat with experience at second, third, and in left field. He's hit .258/.309/.396 with nine homers in 447 plate appearances for the Cubbies after coming over in the deal that sent Ted Lilly to the Dodgers at the 2010 trade deadline. Renck says the Rockies would prefer to get a pitcher in any deal involving Stewart as well.
