PORT ST. LUCIE — There’s bad trash talking, and then there’s good trash talking.

Recuperating reliever Joe Kelly engaged in bad trash talking when he made fun of the Yankees’ October foibles and faux pas after Kelly’s Dodgers became champions.

That was bad for two reasons. One is that it emphasized the Yankees’ weaknesses and unwittingly, and unfairly, de-emphasized the greatness of his own team by suggesting they only beat a loser.

The other issue, of course, is that Kelly was merely a Series spectator.
