When the Chicago Cubs began their NL Division Series clincher in Washington on Thursday night, the Los Angeles Dodgers watched it on their stadium video boards during an upbeat team workout in Chavez Ravine. By the time Wade Davis got the final out in Chicago's 277-minute victory , the Dodgers were long gone home. Whether the rested, hungry Dodgers can use these advantages in any meaningful way against the possibly bedraggled World Series champions will be decided when they get together this weekend to play for the NL pennant again.
