Double Play Following Obstruction

 
With a runner on first base (R1), the batter (B1) hits a double into right field. However, the first baseman is standing in the base path and obstructs B1. The field umpire sees the obstruction and calls the obstruction. B1 is thrown out on a close play at second base. After the tag out at second base, the ball is thrown home, where R1 is also tagged out.
 
The defensive coach likes this unusual 9-4-2 double play. The offensive coach argues that R1 should be awarded 2nd base (maybe even 3rd base) and R1 should be called "safe" at home (or at least returned safely to 3rd base). What do the umpires do now?
 
Call
When a runner is obstructed when advancing to a base, the umpire awards the obstructed runner a minimum of one base (NF only). The umpire can award any runner additional bases that would nullify the obstruction (NF 8-3-2). This is a delayed dead ball scenario (NF 5-1-2b).

In the situation below, B1 was obstructed advancing to second base. B1 is awarded second base in this scenario. The ball remains live. Since R1 was not impacted by the obstruction, his out at home stands.
