The latest controversy over the Dodgers outfielder came in Game 3 of the NLCS against the St. Louis Cardinals when Puig flipped his bat after thinking he’d hit a home run. He ended up with an RBI triple that still stands as one of the biggest hits of his career.
However, many took exception to the play, complaining about his showboating, including Cardinal outfielder Carlos Beltran:
As a player, I just think he doesn’t know [how to act]. That’s what I think. He really doesn’t know. He must think that he’s still playing somewhere else.
He has a lot of passion, no doubt about that — great ability, great talent. I think with time he’ll learn that you’ve got to act with a little bit more calm.
Instead of noticing that he has a .361 batting average in the playoffs with more hits (13) than anyone else in the National League, the discussion is focused on whether he plays the game “the right way.”
