You don't get it. No one is saying Grieve is great, or should start. All he has to do is take a walk to be an improvement over what has been coming off the bench. It's not like anyone on the bench is that much better (aside from Cedeno), particularly Macias. Swapping out Macias for Grieve would be a world of improvement. Grieve is more of a major league player than Macias is or Wilson was, and they were on the team. You are right, the whole season would have been better if Big Ben were here to get a pinch hit walk. And you're right. It's the best thing for the team having Macias come up in critical situations. It always works out for us.
