Helton made it 8-5 with a shot off Franquelis Osoria in a sequence that encapsulated just how snakebitten the injury-riddled Dodgers have been this season.
With the left-handed Helton coming up, manager Jim Tracy came out to get left-hander Kelly Wunsch from the bullpen. But as Wunsch threw his last warmup pitch, he sprained his right ankle and had to be carted into the clubhouse.
"From an injury standpoint, that's probably about the tip of the iceberg," Tracy said.
Just this week, the Dodgers have placed J.D. Drew (wrist) and Cesar Izturis (hamstring) on the disabled list and lost Jeff Kent to a hamstring injury that has left him "day-to-day." Wunsch's injury, which will be re-evaluated Friday, simply added to the misery and may have been the strangest of all.
"That's a first for me," Tracy said.
With Wunsch unavailable, Osoria, a right-hander, came in on short notice and delivered the home-run pitch, making a loser out of Giovanni Carrara (6-3).
