You cannot hang this solely on Hanrahan. He came into a game which was tied and allowed one run on a wild pitch. If the offense had managed to scrape across two runs anywhere along the way we win that game. If Zimmerman goes 4-for-5 last night and drives in four runs and we win 5-2 (even with Joel's WP) none of this matters.
EDIT:
This was supposed to be in response to Chief but he deleted his post.
