Jonathan Broxton blew a save for the sixth time in 13 chances, but that’s a deceiving stat. The first five came before he was closing. The encouraging thing, manager Joe Torre said, was that he came out throwing strikes, something that was absent from his performances on Thursday at St. Louis and Friday night here, when he converted the save both times despite shaky performances. And if Broxton hadn’t made a wild throw on Emmanuel Burriss’ bouncer, maybe he would have gotten Dave Roberts at the plate, and maybe he would have converted the save. If this were a real division race — the kind in which two really good teams fight each other for the lead — this would be the kind of loss that could prove devastating for the Dodgers. But this is the N.L. West, where mediocrity ultimately will reign. And besides, the D-backs lost Orlando Hudson tonight to a wrist injury, possibly for the rest of the season. This race is like a couple of 102-year-old guys who are trying to see who can go the longest without dying. Dodgers fall to 58-58 and stay a half-game behind the Snakes, who will try to avoid a four-game sweep by the Braves tomorrow when they send Brandon Webb to the hill. Yes, the Dodgers missed a golden opportunity. But in the N.L. West, there will be other golden opportunities.
