Why platoon? Give Bernadina the job in CF. He's hitting well, his defense is spectacular, and he's just going to get better since he's nearly 4 years younger than TPlush.
Giving Plush the benefit of the doubt that its just a slump.
I say platoon em for two weeks. If one vastly outplays the other, bench the lesser player full time.
maybe it lights a fire under Morgan and he returns to last years form, maybe Bernadiner just flat out beats the crap out of him.
its a win/win either way.
