To make room for Harris and Soto, who were activated today, Nats sent Kyle McGowin to Rochester and DFA'd Hernan Perez. Yadiel & Espino remain on roster.
TBH, I like DFA'ng Perez. Mercer looks good as a back up, both Kieboom and Garcia can provide depth at MI and 3d base if there's a need, and Davey just has to get Yadi and RZ plate appearances. Espino I guess survives until either Suero or Strasburg is back.
