What Age Group?
Yes you could have rotated up to 3rd base line extended, however, the team didn't do the expected 6-4-3 double play. They instead went for the 6-4-5 DP with a tag play. However, this is not an expected position based on the potential for a pulled foot, swipe tag that may occur on a 6-4-3 DP.
Which coach is asking - Offense or Defensive?
Use your logic to deduce if R3 scored. How?
1) Did R3 go by in your peripheral vision between home and 3rd?
2) Was there sufficent time for R3 to reach the plate prior to the tag play based on your distance from Home Plate, and the tiem you saw him in your vision?
3) Do you believe that if a tree falls in the woods and no one is there to hear it, does it still makes a sound?
As for telling the cheap *** coach that not hiring a 2nd ump is Crap.
Tell the frillin' truth. "Coach, that's a 50 dollar call."
