The Giants surprised the world with a furious two-out rally to turn a 6-0 laugher into a 6-4 game, so when they started the bottom of the fifth with a single, it felt like something that could turn into something more substantial. Joe Kelly walked Buster Posey shortly after, putting two on with one out.
But right fielder/motivational speaker/onbaseophobe Hunter Pence popped out to shallow center. After Mike Matheny brought in Marc Rzepczynski to relieve Kelly, Brandon Belt flew out to end the inning.
One interesting note: Rzepczynski is the only left-handed reliever in the Cardinals bullpen, so there isn't going to be a lot of match-up playing in the late innings. The Giants have Belt, Gregor Blanco, and Brandon Crawford at the bottom of the order, and they've been fond of bringing in Xavier Nady and Joaquin Arias for the latter two against lefties. Which really isn't that scary when you see it typed out like that.
