Friday was a big day for the St. Louis Cardinals. In a division that is up for grabs between four teams, and in a division where not a single team has made any sort of free agent signing, nor a trade that seems to have improved the team rather than simply saved the team money, the Cardinals made two moves that moved the needle. The big deal was their trade to acquire third baseman Nolan Arenado from the Colorado Rockies. Earlier in the day, though, they also signed free agent Adam Wainwright and brought him back to St. Louis.
