When the Washington Nationals’ brass decided to send Carter Kieboom to Triple-A to start the season (or to their Alternate Training site in Fredericksburg, VA, actually) they also had to make a decision on where the infielders who did start the season in D.C. would play. In the end, Davey Martinez and Co. opted to move Starlin Castro from second to third, with Josh Harrison slotting in as the everyday second baseman in the nation’s capital.
How did they decide on Harrison, and why at second base instead of third, since he’s got time at both spots (and several others) in his career?
