Randy Johnson pitched to batters for the first time in his latest comeback from a back injury on Tuesday and then acknowledged the possibility that he might not return this season -- or maybe ever. "I think everybody in this clubhouse, maybe not the players but the coaching staff and front office, would like to know, and I would like to know, whether I'm going to be able to pitch and help this organization," he said. "If not, I think that I need to take care of things and they would need to take care of things." The 43-year-old didn't elaborate but said what he will do depends on how he feels Tuesday night and Wednesday, after throwing 42 pitches to batters before the Diamondbacks played the Marlins.
