Based on the comments of Lawrie's reaction to hitting a grand slam, and there apparently being an HBP shortly thereafter, it made me think he hit the HR, threw his bat 50 feet, punted his helmet and yelled loud enough to be heard on camera the entire time he bunny hopped around the bases. When I watched the replay, and although he pauses for a brief moment in the batters box, his reaction looks no different than many other hitters, and probably much less than some (Pujols, Prince and Braun on occasion, others). There is no helmet tossing until he is safely in the dugout, at which point I really see no way in which his reaction could be seen as showing up a pitcher or being a goon in any way. This in no way proves that he isn't some kind of jerk or whatever, but I don't think this HR can be pointed to as any deficiency in his personality. If someone did get beaned over it, then it is the opposing pitcher who was the goon in this instance.
