PEORIA, Ariz. -- Padres left-hander Christian Friedrich has been diagnosed with a mild left lat strain, ruling him out for the Opening Day roster.
The 29-year-old southpaw, who led the team in starts last season, hasn't pitched since March 17 and won't resume throwing for another week or two, according to manager Andy Green.
Friedrich's absence leaves three candidates -- Trevor Cahill, Jarred Cosart and Luis Perdomo -- fighting for two spots in San Diego's starting rotation.
