My recollection is that Allen is very good defensively. Also, his MLB track record is not good, but it is not a very big sample, and he was considered a top prospect.
He wouldn’t be the first guy to take a couple of years to figure out MLB.
I would like to see them give him a shot. Lots of guys do well in ST, but can’t carry it into the season. I would like to see him get enough of a shot to find out if his ST performance will translate.
His defense has regressed significantly since he was called up. His bat has always been anemic. I feel pretty confident he won't be hitting .400 in the regular season.
