Answer: Pablo Sandoval
The panda man himself, Pablo Sandoval had a great 14-year big league career. Throughout so, Sandoval posted a 19.1 career bWAR, had a .278 batting average, and hit 153 home runs. Most of his glory years came out in San Francisco, where he won World Series' in each even year from 2010-2014.
Sandoval went down in baseball history when he had a memorable three homer game in the first game of the 2012 World Series. That performance spurred him to World Series MVP honors' that year.
