"... RHP Brad Hennessey would be the Giants' closer should anything happen to RHP Armando Benitez, who was unavailable on Wednesday with a knee problem. "We think a lot of Hennessey," Giants manager Bruce Bochy said. "He has the make up for a guy you'd want in late in the game." Benitez was expected to be available on Thursday"
I don't think its anything to worry about. It's all about being precautionary with a "stable" member of a shaky pen who hasn't blown a save all season and granted loading the bases 75% of the time, he gets the job done.
