Have R1 on second, R2 on first batter hits a line drive by the 3rd baseman but lands foul by about 10 feet in left field. Ump ruled fair ball and later stated that 3rd baseman touched the line drive as it went past her. Now here is where it gets interesting, batter saw that ball was well foul and after making a couple of steps toward first she stops and returns to toward batters box then after everyone told her it was fair ball she reversed direction again and ran to first. After play was over I question blue about the fair ball call and he stated the above about contact by the 3rd baseman. I then address the issue of batter/runner stopping and then reversing directions back to home plate. State that batter/runner should be out and all baserunners should have to return to org base becasue she cannot reverse direction going to first. Blues got together and changed then call to foul ball. How can these be done...can a fair/foul call be reversed after the play? I did not push the situation because we had a nice lead but would like to know how this should have been handled.
