Mackenzie McDonald, an unranked 18-year-old wild card from Northern California, qualifies for the Cincinnati Masters. McDonald, who had never won an ATP match before, was given a wild card into qualifying. He had lost in the round-of-16 of the USTA Boys' 18s at Kalamazoo, Michigan earlier in the week.
McDonald overcame world No. 77 Nicolas Mahut and former NCAA champion Steve Johnson to qualify.
"I'm just enjoying this,” McDonald told USA Today. "I'm 18 years old. I'm playing a Masters 1000 main draw that I qualified for, so it's pretty unique."
McDonald said he felt more nervous playing Kalamazoo.
"I definitely felt more pressure out there, because a U.S. Open wild card is at stake, and I really thought I had a great chance to win it," said McDonald. "I did get tight at times there."
