I wish the Twins, when they lose a centerfielder, would call up and use a CENTERFIELDER. Ditto shortstop, third base, etc.
A fill in, or utility guy, for a day or two, OK. But every day? No. Get a replacement up.
That way you probably suffer offensively, but at least you limit the downgrade to mostly one side of the ball.
Let's play Kiersey in CF. Every day.
