TWP that actually happened

[MD Longhorn]

OK, this happened about 2 years ago (and it was in 8U... where all the TWP's happen), but it happened and I've been gone a while. Let some of the newer folks take a shot at this before the big guns come in and answer.

R1 on 2nd, R2 on 1st, no outs.

Batter hits a medium-high trouble ball between RF and CF. R1 takes off, R2 holds to see if it's caught. Ball falls to the ground, but 3BCoach thinks it's caught and yells at R1 to get back. R2 sees it drop and easily makes it to 2nd. 1BC is watching the ball and waiving his arm, so BR keeps going. R2 standing on 2nd when R1 and BR both slide into 2nd at about the same time.

Meanwhile, CF retrieves the ball and throws it over F1's head. F2 retrieves and gets it back to pitcher because that's what she always does.

F1 has the ball in the circle and makes absolutely no indication that she's going to ever make a play.

What do you do?
