Do you call OBS everytime?

I worked a middle school game today with both teams that played surprisingly solid defense.

The F3 for one team, however, while straddling the first base bag, would drop her back knee in front of the base before she would catch a pick-off throw from F2. So as the runner tried to dive back to the base, it was blocked by F3's right foot to her right knee.

I must have called OBS 8 or 9 times. The girl's coach asked about it, but if he spoke to her about it, she didn't change her method of blocking the base.

Never did have to call any OBS on base hits. Both F3s cleared the base for runners to advance.
