Drawing the OBS call

[reccer]

I generally agree with MTD's granting one base penalty, even making it 2 bases if the ball reaches the wall, but might back off this "award" if its a one hop bullet directly at an outfielder.

The decision at first should be an easy one for you. The inside corner of the bag belongs to the runner, and good preventive umpiring makes sure this is so without the offense having to do your job for you.

In my 20 years of playing men's slow pitch. We never had this problem for obvious reasons.

As an aside, I wonder if your view of obstruction is tempered by what type of player you were? If you were slow, and generally only advanced one base at a time, it didn't matter whether you caught the corner as you weren't going any further anyway. To us (former) burners, it makes a huge difference.
