The reeling San Francisco Giants managed just six hits off Ian Kennedy and three relievers, losing 8-2 to the San Diego Padres on Sunday to fall 4 1/2 games behind the Los Angeles Dodgers in the NL West race. The Giants' chances of winning the division were dealt a serious blow by the three-game sweep at the hands of the lowly Padres. The Giants open a three-game series at Dodger Stadium on Monday night. San Francisco is still in good shape to clinch a wild-card berth, although it dropped into a tie with Pittsburgh in the race for the top spot.
