This is about as dirty as it gets when it comes to playing catcher.
With Mikie Mahtook attempting to steal third base, Red Sox Humberto Quintero threw the ball directly at the gut of Durham Bulls catcher Luke Maile.
It appears that Quintero was trying to draw an interference call.
If there is any doubt about the intent, look at how Quintero drops way down side-arm to make the throw. That is not how a catcher ever throws the ball.
