No longer does Andre Ethier wake up in the morning wondering how his right knee will feel. Almost six months removed from a minor knee operation, Ethier said he is free of the pain that crippled him last season and drained him of his trademark power. Ethier hit his first home run of the spring Tuesday, a towering solo shot against Barry Zito in the second inning of the Dodgers' 8-4 loss to the San Francisco Giants at Camelback Ranch.
