Although Marlins manager Ozzie Guillen hasn't completely ruled out using Heath Bell in the ninth inning when the Marlins resume the second half of their season Friday night against the Nationals, the 34-year-old, three-time All-Star knows if he's going to lock down the closer's job moving forward, he needs to be a lot better than he was in the first half.

He needs to pitch like he used to pitch in San Diego. So far in a Marlins uniform, Bell (2-5, 6.75 ERA) hasn't fooled many hitters.
