And let's not forget the Giants' amazing reliever, Pablo Sandoval (0.00 ERA and 0.00 WHIP)!
For those not in the loop, he was a (seemingly) overweight 3rd baseman who made phenomenally athletic plays and hit monster home runs (especially in the postseason, leading to 3 World Series trophies and a WS MVP), earning the nickname "Kung Fu Panda."
Then, in the twilight of his career, he also pitched 2 innings without allowing a baserunner, becoming a bit of an SF meme, including at least one "Let Pablo Pitch" bobblehead.
