Cole Hamels, the Philadelphia Phillies pitcher, has been given a five-day suspension for beaning Bryce Harper of the Washington Nationals on Sunday. (Hamels admitted that the hit was intentional, saying he did it to welcome the 19-year-old Harper to the MLB.) Beanballs are against the rules, so some kind of punishment was certainly in order. But what kind of punishment is applicable in these situations? According to a 2011 law review article, Hamels is lucky to be in the big leagues—and not just for the salary.
