With a struggling Ryan Spilborghs coming to the plate (6-for-35 on the season), and Ramon Ramirez, a righty on the mound, it seemed like a no-brainer that Jim Tracy would call upon Jason Giambi to pinch-hit and take a shot at tying the game up.
Instead, Tracy allowed Spilborghs to hit, and from the first pitch it was clear that he had no chance at the plate. After four pitches, Spilborghs was dispatched, not coming within a foot of Ramirez's split-finger, and the inning was over.
Obviously there was no guarantee that Giambi would have come through in that situation.
He may very well have struck out, just as Spilborghs did. However, there is one reason, and only one reason, why Giambi is a member of the Colorado Rockies. That reason is to hit in that situation.
