Funny enough - Buchholz is the cover man for this approach, which everyone uses. From what I read, it's to give you better grip. I'd rather pitchers have a good grip when throwing 90+ MPH. It's funny watching the pitchers put on sunscreen for the night games...
Pineda had pine tar...he's dumn because you can visually see it.
