Right or Wrong

[wobster]

Playing summer league under OBR. Here's the sitch.

R1, R2, R3, BR hits a grounder to 3B. 3B misfields the ball, but he kicked it, and stops between his feet. He reaches down to pick it up, and is standing directly in the baseline. R2 runs into him, not hard, or probably even intentional, both stumble, R3 makes it to 3rd. What are the penalties.

I ruled basically no penalty. R3 was obstructed, but the fielder was in the act of catching the ball. R2 interfered with F5, but there was already an error which had killed the possibility for an out and he was in the baseline.

Offensive coach says that should have been R2 getting 3B and home. He said obstruction is always an extra base beyond what they could have gotten. I checked it out in the rule book. nope. Rule book states at least one base from the last legally touched base. That was 3rd.

Right or Wrong Guys?
