Am curious views of this non-DQ.

Would appear there is no issue that Alvarado's filly bodyslammed the other filly. The only question was that the fouled filly was looking like an also ran and ended up an also ran. Is the rule that no matter how egregious the foul, if the horse fouled wasn't going to do anything, then no change? She probably lost a placing, but not a significant placing.

if the fouled filly could have finished 4th or better, then this would have been an egregious non-call.

Am I looking at this wrong?
