Bumgarner gem gives Giants 2-0 lead

San Francisco's Madison Bumgarner bounced back in a big way, giving up two hits and striking out eight as the Giants stretched their World Series lead over Detroit with a 2-0 victory. The triumph gives the Giants a two-games-to-none lead in Major League Baseball's best-of-seven championship series as it shifts to Detroit for game three on Saturday. The cushion is an unfamiliar comfort for the Giants, who had to rally to beat both Cincinnati and St. Louis in the previous rounds of this post-season by capturing the final three games in each series. After Pablo Sandoval's record-equalling three home runs highlighted the Giants' 8-3 game one win on Wednesday, pitching dominated game two. Two rough playoff outings for Bumgarner had seen him relegated to the bullpen. But he showed that some work on his mechanics had done the trick as he pitched seven sterling innings in a game that was scoreless until the seventh frame. Brandon Crawford drove in the go-ahead run in the seventh inning and Gregor Blanco added a run-scoring sacrifice fly in the eighth. Blanco went 2-for-3, including a key bunt that advanced Hunter Pence to third base in the seventh, from where he scored the first run. Giants relievers Santiago Casilla and Sergio Romo finished off the two-hit shutout with a scoreless inning apiece. Bumgarner outdueled Doug Fister, the Detroit starter who was charged with the loss although he allowed only four hits and a walk over 6-plus innings. He allowed the first run to reach base by walking Pence to lead off the bottom of the seventh. It was a gutsy performance by Fister, who shook off a scary moment in the second inning when he was hit in the head by a drive off the bat of Blanco.
