The Giants mocked each other by imitating their batting stances and pitching motions

Dance-offs weren't the only things happening at Giants FanFest last week. Several Giants players were also asked to do their best imitations of teammates' batting stances and pitching motions:

McCutchen definitely thought that he nailed Pence's mannerisms:

It'd be hard to argue. "Two pots of coffee already" sounds like the correct approach to Pence's stance.
