Athletics' manager Bob Melvin said Wednesday that he hasn't settled on Josh Donaldson as the starting third baseman. Donaldson is relatively unexperienced at third base and is batting just .240 (12-for-50) this spring, so there's no reason why the job should be handed to him. Eric Sogard is in the mix and might actually be the better all-around option. It's possible Melvin will make decisions based on matchups in the early going, so neither is a particularly appealing fantasy option.
