SAN FRANCISCO None of the clubhouse meetings from calmconversation to intense, in-your-face yelling seemed to work.Neither did all the lineup juggling. The Giants remained comatose through alosing August. So on the last day of the month, with hope nearly exhausted,management used shock therapy on the defending World Serieschampions. They cleared two unproductive and unhappy veterans offtheir roster Wednesday morning, designating infielder Miguel Tejadaand outfielder Aaron Rowand for assignment. The moves were a cold-water dunking for the Giants , who looked awake and alivein their 4-0 victory over the Chicago Cubs to finish an 11-18month.
