The San Francisco Giants brought in Marlon Byrd to help an offense in serious need of jolting. Maybe finding a way to get Madison Bumgarner in the batter's box semi-regularly would help too. Bumgarner smashed his fifth homer of the season and Byrd drilled his 20th in his first game with the defending World Series champions as San Francisco held off the Pittsburgh Pirates 6-4 on Friday night to climb within 1 1/2 games of the Los Angeles Dodgers for first in the NL West.
