According to Jon Heyman of CBS Sports, the Cardinals "have not called the Rockies" about Troy Tulowitzki.
Heyman adds that the Rockies have "no interest in trading Tulo anyway." The Cardinals need a shortstop badly and have the kind of pitching prospects that the Rox desire, but it's very rare for a star to be traded during spring training. The Rockies are trying to sell tickets right now. The idea can be revisited this summer.
