PHOENIX -- Dodgers reliever Javy Guerra was activated from the disabled list Thursday, but his role in the bullpen is still to be determined.
"We'll probably just try to get him out on the field one time and get him comfortable first," Dodgers manager Don Mattingly said. "We'll just use him accordingly and try not to overtax him at the start of this."
Guerra, who is 2-3 with a 3.38 ERA, had been out since June 3 with right knee inflammation and had arthroscopic surgery on June 5. He started the season as the team's closer but was eventually replaced by Kenley Jansen after early-season struggles.
