If the umpire saw what he saw, this is what he gets: a loose-loose situation. I agree with Irish, you don't want to see all of it!
Yes, we are supposed to get it all right. However I do think we also have to do/call what is fair. In this case not seeing the OBS, so not award 3th base is more fair than award a runner (that should be put out on the force) a base.

Last saturday as PU I call "Play ball" after a foul. Batter comes up, turns her head and asks me "What?". F1 is already in her wind up, but stops her motion and the pitch... Complete unfair was my justified call: IP. The batter gained an advantage out of a stupid act. I didn't feel bad, if F1 completed the pitch it would have been a strike. She didn't, thus IP.

Coming back to our situation. F6 screw up. But was that enough to award R1 a base? Don't think in rules, think fair/unfair and let the rules support your opinion...
