Lets use Houston as an example with the yellow lines in the outfield. Bases loaded 2 outs ball hits the outfield wall careens past the outfielders (however outfielders give up on the ball when they see the HR signal or they don't see the signal and hustle after the ball) in such a way that all three runners will score BR will have at least a double and probably a triple. However umpires signal home run. Crew chief decides to review and reverses the home run call. How many runs will score and where will the BR be placed? Will the fact that the outfielders either saw or didn't see the HR signal be an issue concerning the placement of BR and the runners?
