In the bottom of the sixth, the Reds made a modest bid to break Game 2's 1-1 tie, but failed.
In top of the inning, with Giants starter Ryan Vogelsong having thrown 95 pitches, Aubrey Huff pinch-hit for Vogelsong (and struck out). That meant a new pitcher for the Giants, and lefty Jeremy Affeldt got the call.
After a couple of quick outs, Jay Bruce took one for the team and Scott Rolen reached safely on a swinging bunt. Would Bruce Bochy bring in a right-hander to face Ryan Hanigan? Nope. Affeldt isn't just a situational lefty, so he stayed in the game and retired Hanigan on a grounder to end the frame.
So in the top of the 7th inning, the score's still even despite the Giants having just one hit in the whole game.
