I get the fan instinct and where MorsetheHorse and others are coming from - "I'm sick and tired of the losing, Bryce is a STUUUUD, if he helps us win three games in April, those might be the three we need to make the playoffs, etc."
But the flaw in that thinking is this. Some one asked recently (paraphrasing) "what has Harper done to prove that we would win more games right now with him than with, say Ankiel, who probably would be cut or sent down to make room for Harper". And of course, nobody answered that question.
