5:12pm: The Cubs and Blue Jays continue to discuss a Garza deal, Jim Bowden of MLB Network Radio and ESPN.com tweets. The Cubs seem to be prioritizing young starting pitching in talks about Garza, tweets Jon Heyman of CBSSports.com. One executive told Heyman that the Yankees and Blue Jays have what it takes to acquire Garza.
12:53pm: Trade talks for Cubs starter Matt Garza are heating up, writes David Kaplan of Comcast Sportsnet Chicago. Kaplan says the Blue Jays, Yankees, and Red Sox are involved, but the Cubs' asking price is "incredibly high."
Yesterday, MLBTR's Ben Nicholson-Smith took an in-depth look at Garza's contract situation; he's under team control through 2013. Cubs president Theo Epstein said on Friday that Garza is "exactly type of pitcher we want to build around," but he'll listen on everybody. So far this winter trade values have been established for Gio Gonzalez, Mat Latos, and Trevor Cahill, but all of them came with at least four years of team control.
