The Rockies were in the mix on Parra from the start, joining the Nationals, Angels, Orioles, and Royals who all showed interest at one time or another.
With the addition, Colorado now has a surplus of outfield pieces and could look to move Charlie Blackmon or even Carlos Gonzalez in a trade. In fact, the Tigers and Orioles are already reportedly in trade talks, meaning something could come together rather quickly. Parra has spent significant time at all three outfield spots.
In Coors Field, Parra's overall offensive production may increase, but thus far it has been generally below average, with 2015 being his first season since 2011 with a wRC+ of over 100 (league-average). At the very least, Parra adds depth and could be the generator of a trade out in the Rocky Mountains.
