This isn't the kind of trade most of us were hoping for. There have been a lot of fans who have openly complained about how the team should have traded Penn a long time ago, back when he was tearing through the minors, for help. Hoping MacPhail would get a second base or shortstop prospect in return. Then, there were those that believed Penn might "figure it out" this spring. Sadly, those days are long gone.
It is, nevertheless, a realistic trade. One that bolsters this team's bench and allows for Trembley to focus on 12 pitchers instead of 13. Andino played second, short, third, and center in his four years in the majors and was out of options. As a solid defensive-minded guy with a career line of .201/.299/.250 in 144 ABs in 79 games this trade makes sense for the Os who really did need back-up up the middle with some speed. And they got just that.
P.S. - When you search for Andino on mlb.com you'll notice that they have him marked as an Oriole.
