Sorry Roch, but I have a feeling that the only way we'll see McKenna again in an Orioles uniform is as an brief injury call up if an outfielder has a bad ankle twist or something and needs a short IL stint. And that's assuming that we don't decide to bring up Stowers instead. Which is likely, because if I recall correctly, Stowers is on the 40 man right now, and McKenna isn't.
McKenna will be a free agent next year, and could potentially be a 4th/5th OF fit for many of the teams in the bottom third of the league... I'm sure he'll sign elsewhere to get a shot at an MLB roster, as he's not high enough on our depth chart anymore for any lengthy shot at ours.
