Favorite Coach rule misapplication

[3appleshigh]

R1 and hot shot to CF, R1 has wheels, and and rounds 2 going to 3rd, CF launches a quality throw in to the dugout. I award R1 home and BR 2nd as he was about 3/4 the way to 1st when the CF throws the ball.

Coach comes out and asks why BR is on 2 not #rd, I explain, and he says no way, he got the ball through the infield, he is "given 1st base", He got a hit so he was "given 1st base", I said, no he was given anything until the ball went out of play. The coach throws up his hands and leaves. He talk to me again after the game nicely about it, and still thinks he is right.
