I think Barrero needs a real shot where he's healthy and ready to go. He should be the starting SS next year at least for a couple of months if not all year.
In Senzel's case, I thought the same coming into the season and he got that shot and stunk up the joint. He's arb eligible and will be 28 in June. He's out of time IMO.
Agree on Aquino, time to move on.
