INTERFERENCE (a) Offensive interference is an act by the team at bat which interferes with, obstructs, impedes, hinders or confuses any fielder attempting to make a play. If the umpire declares the batter, batter-runner, or a runner out for interference, all other runners shall return to the last base that was in the judgment of the umpire, legally touched at the time of the interference, unless otherwise provided by these rules. According to Ueck the throw beat Rendon anyway. Even if it didn't, how could he have reached first at the time of the interference, unless the interference happened well after the throw, and in that case how is it interference? It has to be a blown call.
