The San Francisco Giants acquired outfielder Marlon Byrd and cash Thursday from the Cincinnati Reds to boost their injury-plagued outfield for the stretch run. A day after losing out on second baseman Chase Utley, whom the Philadelphia Phillies traded to the NL West-leading Los Angeles Dodgers, the defending World Series champions made their own move to replenish an outfield that has dealt with injuries to all three starters. San Francisco trailed the Dodgers by two games at the start of the day.
