You could keep Ed Brinkman and his .188 because he was a brilliant shortstop. Espinosa might be a brilliant shortstop too but he's not playing there, and he isn't valuable enough at second base to sustain him and his .188. Move him to shortstop and bench Desmond, or bench Espinosa. It's really as simple as that.
Bench espinosa and start Lombo. Although I think Brinkman was at least a .200 or .205 hitter!
Beyond Desmond, Lombo, and espinosa, the organization seems a couple of years away from help in the infield. Waiting for Rendon (injured at Potomac) or Kobernus (Harrisburg).
