When B1 hits a line drive and F5 knocks it down but throws wildly into dead-ball territory, what is B1 awarded?

In the scenario where B1 hits a line drive and F5 knocks it down but then throws the ball wildly into dead-ball territory, B1 is awarded two bases from the base he was at when the pitch was thrown. Since B1 is likely on first base at the time of the pitch, the award would be two bases, meaning he is allowed to advance to second base.

This situation falls under Rule 7.5 regarding a ball thrown into dead-ball territory. The official rule states that when a fielder makes an attempt to make a play but fails (in this case by not successfully throwing the ball to a base), the runner is granted the appropriate number of bases. Since the throw went into dead-ball territory, it is treated as a delayed dead-ball situation that allows the runner to take additional bases.

Thus, B1 is indeed awarded second base after the errant throw into dead-ball territory, making this the appropriate ruling in this situation.
