Monterey County fire crews responded to a report of a grass fire in Salinas this afternoon. The blaze, which was reported just after 3 p.m., burned an open field on the east side of Old Stage Road across from Spence Road. Fire officials say the fire was quickly contained due lots of open land around the flames. The cause of the fire awaited confirmation from PG&E officials, who were on scene examining a power pole at the edge of where the fire began. No structures were damaged or threatened, and no injureis were reported.
