That doesn't mean it will happen this time. Whatever pattern of behavior that exists or doesn't exist will be part of the review. There's a perception of a pattern of behavior in the minds of the public that has to be taken into account. In the past, hitters have been penalized for throwing bats at pitchers, most notably Oakland's Bert Campaneris. It was an unusual incident.
Intent is always difficult to establish.
Any suspension would not start until next season, because the players' association almost certainly would appeal, delaying any penalty until after a hearing before Paul Beeston, baseball's chief operating officer. I think to be thorough about it, that's probably the right thing. And very often, I've disagreed when people have been thrown out of games. So I don't think I'm a very good arbiter in that manner.
