The Case of Kenny Rogers and the Pine-Tarred Hand

I have a simple question for this: Why would Rogers have pine tar on his hand for the whole world to see, especially during the World Series? Kenny Rogers isn't that stupid. Even Joe Niekro hid the sandpaper in his pockets when he got caught. There has got to be another explanation.

Maybe baseball fans have gotten cynical. No one can do amazing things anymore without cheating.
