FOX Sports MLB Insider Ken Rosenthal put the baseball world on its ear Monday night when he broke the news that the Colorado Rockies traded five-time All-Star shortstop Troy Tulowitzki to the Toronto Blue Jays in what ultimately became a six-player trade and swap of shortstops.

Toronto is sending four-time All-Star shortstop Jose Reyes back to Colorado, though there is plenty of speculation that Reyes will soon be traded again, as the Rockies already have their shortstop of the future sitting in the minors.

Nonetheless, Tulo is a Blue Jay after 10 seasons in Denver. While the thought of Tulowitzki in a uniform other than that of the Rockies may seem shocking to many, there was no shortage of speculation in recent years that the Rockies, if they failed to start winning with consistency, would ultimately ship off one of the greatest players in franchise history.
