When the Arizona Diamondbacks decided to trade fan-favorite infielder Blaze Alexander to the Baltimore Orioles, the reactions were (understandably) mixed, to say the least. When right-hander Kade Strowd (the primary return of the deal) did not break camp for the D-backs after spring training, the noise grew louder. When Alexander delivered a walk-off base hit for the Orioles on Opening Day, the trade looked even uglier. And when newcomer Nolan Arenado — whom the D-backs brought in from the Cardinals, and pivoted to full-time at third base in place of Alexander — held an OPS in the .300s through his first eight games, it looked like the Diamondbacks made the wrong decision with regard to their infield. But it does not look that way now. What a difference three weeks can make.
