Jonathan Lucroy drew a leadoff walk in the 10th against Matt Guerrier (0-1) and Morgan came on as a pinch-runner. Morgan stole second and moved on to third on the play when the throw from catcher A.J. Ellis sailed wide.
Two intentional walks loaded the bases before Braun sent a fly ball to shallow center. Third base coach Ed Sedar signaled that Morgan should stay on the bag, but Morgan headed home anyway and was called safe by umpire Mike DiMuro.
Replays indicated the tag was applied to Morgan before he reached the plate.
