After a historically bad run, the San Francisco Giants will be riding the momentum of a rare win when they seek revenge on the Cincinnati Reds in a four-game series that begins Thursday night. The series is a rematch of a three-game demolition by the Reds in Cincinnati last week. The Reds won the games 13-3, 14-2 and 4-0 -- beating San Francisco by a cumulative 26 runs, the Giants' largest margin of defeat in a three-game series since getting trounced by a total of 37-10 by the Pittsburgh Pirates in 1922.
