I think you're right. Pettiti was indeed in the last frame, so that might be Proctor (71), Peterman (72) or Batiste (78). Glad to get Pettiti's name "cleared", I kind of like him myself so hate to see him get mauled over.
And since the guy already has a star on his helmet, I further ruled out Proctor and Batiste...
so Peterman it was. Agree?
