"We are very sure that Robb is going to be healthy, but I believe the way Herges threw in the playoffs and the way he pitched last year, he can close games," Alou said. "I said last year (Tim) Worrell could close games for me, and he did. I believe Herges could close games for me." The Giants don't have insurance on Nen's contract, so they probably won't be able to go out and acquire a closer if he suffers a major setback. That makes both Herges and Rodriguez sleepers.
