ELI5: Why would a baseball pitcher use pine tar?

In light of the Yankees pitcher being ejected from the game for having pine tar on his neck, what's the advantage of it?

A lot of pitchers do this to get a firm grip on the ball, especially on windy days. When a pitcher is singled out and thrown from a game, it's usually because he's being obvious and obnoxious about doing so; such was the case in yesterday's game. Pineda was caught using tar in a game against the Red Sox on April 10th and shrugged off allegations, though he knew that the Sox let him off with a warning. Blatantly running his hand across his neck less than a month later was a middle finger towards his opponents ... So they called him out on it.
