Ortiz or Stassi?

I can't believe I've completely overlooked Ryan Ortiz. The former Beaver was 4th in OPS (.873) among fellow A's farmhands that did not see any big-league playing time with at least 200 Plate Appearances. The only ones in front of him are Stephen Parker, AJ Kirby-Jones, and Grant Green. Maybe Ortiz will be Kurt Suzuki's successor whenever that time comes.
