Jenson Brooksby d. Pedro Martínez

Starting an hour and a half late because of a rain delay, Brooksby, an 18-year-old Californian also known as J.T., won and became the only American man to reach the main draw through qualifying. Last year, Brooksby got a wild card into the main draw when he won the junior national championship in Kalamazoo, Mich. He lost in the first round to the Australian John Millman, who went on to upset Roger Federer in the round of 16.

Brooksby could have competed in Kalamazoo again this year, but he opted for the challenge of U.S. Open qualifying. He played before a packed house of more than 1,500 on Court 11.

“I just felt like I had worked so hard, I was a year older and I felt ready,” Brooksby said after he defeated Martínez, a 22-year-old from Spain , 6-3, 6-7 (4), 6-3. “Coming through qualies is incredibly tough. I’ve never played in front of a crowd this big.”

Brooksby led by 5-3 and served for the match at 5-4 in the second set, only to double-fault on break point. After a brief rain delay in which both players stayed on court, Brooksby dropped the tiebreaker. He then sat in his chair while Martínez called the trainer. Brooksby removed his baseball cap and repeatedly ran his fingers through his hair.
