Arroyo's double lifts Giants to 13-inning win over Cardinals

ST. LOUIS - Christian Arroyo's two-run double broke a scoreless tie and the San Francisco Giants beat the St. Louis Cardinals 3-1 in 13 innings on Saturday night.

Arroyo's double off the wall in left field scored Buster Posey and Brandon Crawford and came on the 12th pitch he saw from Cardinals reliever Kevin Siegrist (0-1). Posey, Crawford and Eduardo Nunez singled to load the bases, giving the Giants their first runners in scoring position in the game.

Giants starter Jeff Samardzija threw eight innings, scattering five hits and striking out eight. He threw 75 of his 105 pitches for strikes.

Hunter Strickland (1-1), Derek Law and Josh Osich pitched in relief for the Giants, who won for the seventh time in their last eight tries.

Mark Melancon earned his eighth save.

The game was stopped for 42 minutes after the 10th inning for a rain delay.

Cardinals starter Carlos Martinez pitched nine innings for the first time in his career, but fell victim to lack of run support. Martinez gave up two hits, struck out five and needed just 93 pitches to get through nine innings.

Matt Bowman and Trevor Rosenthal each pitched a scoreless inning in relief for the Cardinals, who dropped their fourth straight.

Matt Carpenter led off the bottom of the ninth with a double, but was thrown out at third trying to stretch it into a triple, thwarting the best chance either team had of scoring in regulation.
