I don't doubt that the FO gave him 2+ months of shitty non-performance as cover for yet another vet mistake. But running him out there over and over going forward serves absolutely no purpose. He is not part of the future, there is nothing further to evaluate in his (lack of) performance, and there are AAA/AAAA hitters more deserving of his roster spot. If the FO cares about putting together a productive roster moving forward, there is absolutely zero reason Alonso should remain on the roster period.
