The Blue Jays have struggled to improve their starting rotation this winter and acquiring Matt Garza via trade with the Cubs is unlikely, according to Major League sources. Toronto failed in attempts to trade for Mat Latos or Gio Gonzalez and they were outbid on Japanese right-hander Yu Darvish. Garza is under club control for only two more seasons and the Blue Jays aren't willing to give up top prospects for a relatively short-term addition.
