If you can't hit, if you play more than a game or two as a substitute you are a negative part of the team. So you have to hit some. The D never can really make up for being a hole in the lineup. That is old fashioned National League ball.
I know we don't want to "yoyo" prospects. But how much of a yoyo is it to bring Akin up for two days? It's not like a normal season when he would have to pack his things, leave Norfolk, find a way to Baltimore, find a place to stay in Baltimore for a short period, live out of a suitcase while up here, then go back to Norfolk.
Assuming he is living somewhere near Bowie, it just means instead of driving 5 minutes to Bowie Stadium, today and tomorrow he drives 25 minutes to Nats Park. He still sleeps in the same bed each night.
