Catcher Spencer Kieboom: Kieboom is the first of two catchers in the Nationals system that will be playing for the Solar Sox. He spent the entirety of the 2014 season in Harrisburg where he played in 87 games after playing in four, in 2013.
He was able to hit for power as nearly half of hits for extra-bases, 28 of them being two-baggers. He finished the season hitting .309, and had a .352 on-base percentage. He has already missed a full season so playing in the AFL is huge for him to face big time pitching.
He is not ranked by MLB.com as a top Nats prospect.
