This is what rotoworld has to say about it.
Jeff Fassero will be sent back to the bullpen now that the Giants have Jason Schmidt back.
Brad Hennessey stays in the rotation. Manager Felipe Alou said he'd give Fassero a chance to close games when Tyler Walker needs a night off, but don't read a lot into that.
I tend to agree with rotoworld, Walker has gotten 6 saves and hasn't given up a hit since being named the closer so there's not reason to bring anyone else in during save situations now, atleast until walker blows a couple. Unless Walker needs a night off that is. I need Walker to stay in the closers role, he's my only active closer because I have Dotel, Lyon, Percival and Affeldt all on the DL.
