Off the subject a little but I heard a commentator during the 6th inning speaking about the base runner running down the line to first and beating out a hit and passing first, then an overthrow. She made mention that if the runner passed first base and made even one step towards second, she could have been out when tagged by the defense. I could be wrong here but I believed that you have to make a legitimate attempt to advance to be at risk of being put out in this situation. I would not think a step to the left(towards second) would meet this standard and ultimately, it is the opinion of the umpire that matters.
This may be a new emphasis for umpires this year. I played in a big midwest tournament last week and umpires call my girls out at first twice for simply looking at second-no step and still on the baseline returning to first when they got tagged.
I was not happy nonetheless.
