I think Stowers development is happening just is time.
The O's have 30 games in 31 days coming up. That is the grind. And with Santander, Mullins, Hays, Cowser and Stowers ability to start in the outfield and at DH the O's should be ready to withstand the fouls off the foot, the pains from the dives and hitting the wall every now and then.
For me it's not about is there enough playing time. Its with the injuries, bumps and bruises is there enough time to rest.
