Look Back Rule

[WestMichBlue]

R1 off 3B with the pitch; comes to a stop when batter does not swing. F2 steps out in front of plate and fakes throw towards 3B; R1 starts back to 3B.

Ball is returned to F1 in circle who turns and looks at R1. R1 stops and looks back at F1; then, within a second (or so) turns and continues back to 3B.

Would you allow that second stop? Or call R1 out?
