I have nothing much to add about Tyson Ross coming up to replace the injured Michael Wuertz, who has not pitched yet this year and is apparently dealing with a hamstring problem. Ross is an adequate last man (or second-to-last, since I simply refuse to believe that he's worse than Bobby Cramer) in the bullpen and can be trusted with low-leverage situations where a walk or two won't kill you.

This leaves the A's bullpen this way, ranked from highest leverage to lowest, i.e. who I trust most with the toughest situations:

1. Grant Balfour
2. Craig Breslow
3. Jerry Blevins
4. Brian Fuentes
5. Brad Ziegler
6. Tyson Ross
7. Bobby Cramer
