It's not as clear in OBR. The BRD quotes a MLB umpire as saying that the BR is liable to be put out unless there was some reason for him to run hard to 1B. I guess this might mean a pitch getting away from the catcher on ball 4 or something. Or maybe he thinks ball 4 was strike 3 uncaught and runs hard.

MLBUM says you CAN overrun on a walk.
