Why can’t we hit fastballs?

Seems like we come up empty on balls middle middle at like 90-94MPH. It’s weird. Also I understand if Trout and Soler just wanna jack every time but Adell, Ward, Rengifo and others need to shorten up with 2 strikes and settle for contact. We are striking out way too much and even when we hit a HR about 80% of the time it’s a solo shot-because we have no one on base! We need to get some ducks in the pond and let Trout, Soler, and Ward bring them home.
