Animated relief pitcher Jefry Yan may be polarizing to Mets fans

This is going to be fascinating to watch unfold. 

It is the type of thing that Mets fans will probably love because he plays for them, and because it is going to at least bring some excitement and juice to a completely lost season that has been miserable from the start. Remember when Lastings Milledge hit his first Major League home run 20 years ago and then celebrated by doing a victory lap and high-fiving fans on his way back out onto the field? Mets fans loved it. 

Old school baseball people, on the other hand, hated it.

While there has been a push in recent years for baseball players to show more emotion and flair in their performances, there is still a significant old school thought process that frowns on these things.

They see the baseball diamond as sacred, and that should be treated with respect.

The whole "act like you have been there before" mentality. 

There is also a chance that it is not going to be well-received by hitters on the wrong end of a strikeout and walk back to the dugout in the bottom of the seventh inning of a blowout game. Words will probably be exchanged at some point. Maybe the benches empty. And, hey, maybe that also brings a level of excitement.

But another way of looking at this is that it is simply a pitcher turning the tables on hitters in a celebratory sense.

Bat flips have not only become a normal part of baseball, but they are widely accepted forms of celebration, as are slow home run trots and celebratory gestures after any extra-base hit, let alone after a ball leaves the park. Why shouldn't pitchers be able to throw it back in their faces a little bit? Yan is taking the opportunity, even if it's not meant to be a dig at hitters and is just an overflowing sense of excitement and love of the game. It remains to be seen how long of a career he has in the Major Leagues, but he is almost certainly going to make it one that people talk about.
