Brantley stepped on Kelly because Kelly was blocking the plate. Don't want to get stepped on? Don't put your foot on the front edge of the ******* bag.
I don't think Kelly was intentionally aiming for the Astros heads. He's always had control issues and he couldn't find his curveball. To me, it wasn't intentional. But also, the Astros need to keep their goddamn mouths shut and realize that they did this to themselves IF those errant throws were intentional. Jeff Blum did make a good point during the broadcast though...he said he could understand taking a shot at someone's ribs or backside, but throws at the head are not ok. Kelly has been suspended in the past for that shit, so maybe it was intentional and maybe that's why they dished out an eight-game suspension. Who knows.
