DETROIT — Pablo Sandoval did it while walking toward the camera in the dugout and again while pulling into second base with an eighth-inning double. So what was with the heart-shaped signal that the Kung Fu Panda was making in San Francisco's 2-0 win over Detroit in Game 3 of the World Series on Saturday? Even his teammates didn't know, though they were plenty willing to hilariously mock him in the dugout after he did it. "I was just messin' around in the dugout. I don't know what it is," reserve infielder Ryan Theriot said. "He does it, and we were really kind of just making fun of him." "Maybe he's a big Taylor Swift fan," shortstop Brandon Crawford said.
