I concur (never had to rule on the FED caseplay sit) but I have a nagging question about a play I just saw. Bunted ball down 3B line. F3 set up behind 1B and we get the out. Offense says he slowed down my runner who peeled off in stride to avoid trucking the F3. I have nothing but it might be a intentional position to affect the runner. Do we require a train wreck here? That's what that offensive coach is going to tell his runner next time.
