In FED softball, their are no more train wrecks. You either have:
a) Fielder has ball, runner contacts fielder for a tag out, interference, and/or malicious contact.
b) Fielder does not have ball, runner contacts fielder (unintenionally), obstruction on the fielder.

A throw that takes the fielder into the runner is NOT obstruction in NCAA BASEBALL or LL BASEBALL. Why would softball ever be considered a model for baseball - they are two very different sports.
