Late in the third game, Johnson was walking toward his bench when he tossed his paddle at his bag, but it accidentally struck a nearby spectator, resulting in a forfeit that ultimately ended the contest at Life Time Arden.

Ford automatically advanced to the semifinals against No. 6 Jack Sock.

It actually wasn't the only paddle toss that made headlines on Friday.

After falling to No. 2 seed Kaitlyn Christian in three games in the women's singles quarterfinals, No. 7 seed Isabella Dunlap flung her paddle into the fence in frustration before approaching the net to congratulate her opponent.

Both matches took place on Grandstand Court.
