If Frank wouldn't dream of bringing Guzman in as a pinch hitter, why start him? Let the pitchers bat ahead of him. ...And last week Frank had him bunt with two strikes. I don't think I've ever seen that with a non-pitcher.
With a man on 1st Guzman should be instructed to bunt and deliberately miss. It brings in the infield and makes a steal easier. Oh I forgot, the Nats don't steal bases.... With anyone on 1st and/or 2nd, "Double-Play Guzman" should deliberately strike out to avoid the double play. He can't bunt and he can't hit a sacrifice fly. He should be traded, even if they have to buy down his contract for the other team.
