Pena knocks in winner, Giants beat D-backs 5-4 in 11

PHOENIX (AP) Pinch hitter Ramiro Pena doubled in a run from first base in the 11th inning and the San Francisco Giants escaped with a 5-4 victory over the Arizona Diamondbacks on Sunday to take two of three in the series.

The Diamondbacks' Jake Lamb hit a two-run home run in the eighth inning to tie it 4-4 but Enrique Burgos (0-1), Arizona's seventh pitcher of the game, walked leadoff batter Jarrett Parker in the 11th and Pena lined the first pitch he saw into the right field corner, giving Parker time to score.

Josh Osich (1-1) pitched a scoreless 10th to get the win. Santiago Casilla escaped trouble in the 11th for his 19th save in 23 tries.

The Giants took a series from an NL West foe for the seventh straight time. The last series they lost to a team in their own division came when they were swept at home in four April 18-21.
