I watched the replays after seeing the original post. It's hard to disagree with anything you said. The interesting thing, however, is that the hole the 6 was trying to go through was closing from both sides. While the 4 was came out, the 5 was also coming in and being hit right-handed, and the 4 had actually straightened out when the contact occurred. Yet the 4 gets DQ'd and the 5 gets moved up. Tough call.
