The Nationals will try for a sweep of the Giants tonight against Matt Cain, who of course threw a perfect game earlier this season. Both teams are wearing throwback jerseys from 1924, the last year Washington won the World Series. Ross Detwiler will try to play the role of a left-handed (but not eight-armed) Walter Johnson. The best part about the throwback night is the grounds crew in suspends and bowties. Talk about the game right here.
