FED. B1 hits a ground ball to short. Shortstop's throw is to the home plate side of first (bad throw). B1, seeing it's a bad throw and F3 is coming off the bag toward him, veers around F3 who ever touches the bad throw. The umpire calls "That's obstruction". The throw goes to the fence, and B1 goes safely into second base. The defense then appeals B1 missed first base, which in fact he did. The offensive coach says he missed it because of being obstructed by F3.

What's the call?
