The Giants, who lost Sunday to the Arizona Diamondbacks, 5-1, have dropped nine of their last 10 games. After losing three of four games to Arizona, the Giants own a disappointing 1-6 record at home. Their 4-10 overall mark matches that of four other teams (1980, 1983, 1985 and 2000) for the club's worst after 14 games since the franchise moved to San Francisco in 1958.
