LOS ANGELES >> Brandon McCarthy is all too familiar with the process of being injured, rehabilitating and returning to action.But when his elbow gave out 14 months ago, he said the fear entered his mind "that it could have very well been my last pitches."They weren't.McCarthy returned to a major-league mound Sunday afternoon at Dodger Stadium and pitched five scoreless innings as the Dodgers completed a three-game sweep of the Colorado Rockies with a 4-1 victory.
