Ian Crouch on Michael Pineda and the pine tar: http://nyr.kr/1iRIvvR

“Pine tar may improve a pitcher’s accuracy, thus cutting down on dangerous wild pitches, but it can also make his curveballs and sliders markedly better. There is some romance in the notion of a crafty pitcher using handed-down secrets of the trade to gain a slight advantage on the mound.”
