Catcher covering third base

[mbyron]

I see 2 possible explanations for the apparent no-call:

1. What JM said: OBS WAS called, and the runner was protected to 3B. BUT, the remedy for Type B is negating the OBS, and with the ball rolling way out to LF a runner could have scored. I doubt that the award would have been only 3B.

2. The runner was hurt, and so lying on him didn't hinder him or prevent him from advancing.

Nothing suggests that OBS was called at all, which further undermines (1), so I think (2) is better.
