"It was kind of annoying. It was like something about, 'Go ahead and cry to your mother again.’ It made me pretty mad. So I said shut up. It wasn’t beneficial," said Young. "And I was down 5-6, all that combination wasn’t great."
The defeat could see Young, currently ranked No. 47, fall from the Top 50 in the rankings.
