Who's call?

[chris s]

This one happened to me in an elimination round of a PONY sectional.Very close game, 1-0 in the 3rd, both pitchers are getting ground balls and throwing strikes, I have the dish.
Weak grounder to F1, very fast runner booking it to first, soft toss by F1 to F3 results in F3 leaving bag and catching ball about 10 feet towards home, he is right on the line.
Br is a few steps from F3, he then veers well outside of the lane as F3 attempts a swipe tag and misses. Br then stumbles and misses first as f3 tosses to F4 at the back of the bag. Br then scrambles to bag and obtains posession before another tag. BU, after a loooong moment, then sells a safe.
Now defensive skipper comes out asking me if I had a better view. I ignore for about 2 seconds and then repeatedly tell him to ask the ump who made the call.
After skipper asked partner for help, BU comes to me and I relate that I have an out of baseline/attempted tag situation, "bang the runner ", I tell pard.
Pard changes call and there was no bitchin(surprise). Now between innings, offensive skipper comes to me and asked who's call is it. he did not have a beef, told me call was right, but he was curious as to the mechanics. If it was before the 45(40) foot line, I surely would have nailed it, but 10 feet from bag??
after game, BU told me he was freaking lost, total brain fart. He was screened by his not so good angle, that happens, but, I am at a bit of a loss. Should I have banged runner as soon as I saw the avoiding infraction??
