Rocco is far from faultless. However, the problem yesterday is that a succession of relievers failed to do their jobs. The 100% 20-20 hindsight that X should have thrown a second inning becomes cherry-picking. I've said it before, the rotation has been successful, but it is both brittle and fragile. That means little trust for long outings and a quick hook in close games.
The bullpen has been exposed too often and they have injury excuses (currently Smith, Coulombe and Alcala on the injured list), but there isn't enough quality there, even at full strength, to cover for the additional innings the rotation puts on them. Baldelli gets the abuse for covering for and protecting his bullpen. I guess that is part of the job..
