Mike and mcrowder have pretty much captured my thinking process.

Obstuction has been a personal POE for me for the last year or so. I felt like I was missing too many calls and not ruling properly on the ones I did call. This call in particular, at first base on a hit, has been part of my focus.

This was a B level tournament, so it is entirely possible that the player had not been coached properly to get away from the bag on a hit, then come in behind the runner for a possible throw.

In most cases on this call, nothing is going to happen, and few will even notice the arm out for OBS. On this particular play, somebody noticed and it resulted in a play I had to make a ruling on. I'm comfortable with my ruling on the field.

I posted here to bring attention to this type of OBS, because I notice a lot of umpires on a base hit are lazy about getting into the infield and making the pivot to watch the BR touch first and pick up this particular type of OBS.
