Editor's Note: This story was published on 26 August 2019. Brooksby is now facing No. 17 seed Nikoloz Basilashvili of Georgia in the second round of the US Open.

American teenager Jenson Brooksby enjoyed a breakthrough moment on Monday at the US Open, defeating former World No. 4 Tomas Berdych of the Czech Republic for his first tour-level win. It was also the 18-year-old’s first victory over a player inside the Top 100 of the ATP Rankings.

Brooksby will face No. 17 seed Nikoloz Basilashvili in the next round. ATPTour.com looks at five things to know about the right-hander.

1. Brooksby Enjoyed Plenty Of Junior Success
The 18-year-old’s only previous tour-level appearance came as a wild card in last year’s US Open, which he earned by winning the USTA Boys’ 18s National Championships. He also reached the semi-finals of the boys’ singles event in last year’s US Open, which marked his final junior tournament.

2. He’s On A Hot Streak
Prior to his New York moment, Brooksby won back-to-back singles titles at ITF Pro Circuit events in Illinois. He clinched his first professional singles title this March at an ITF Pro Circuit event in California and earned his maiden ATP Challenger Tour main draw win the following month in Sarasota.

3. His ATP Ranking Is About To Soar
The 18-year-old is currently No. 394 in the ATP Rankings, but is projected to jump to around No. 280 when the newest standings are released. Should Brooksby win his second-round match, he will climb well inside the Top 250.

4. He’s Headed To College
Brooksby signed a letter of intent to play college tennis starting in January at Baylor University in Texas. He plans to play several professional tournaments before then.

"Jenson is one of the strongest competitors I have seen and has a love for the game that is second to none,” said Baylor Director of Tennis and Head Men's Tennis Coach Brian Boland. "The combination of his innate skill set and incredible work ethic have helped him separate himself from his competition at every age group.”

5. He Might Turn Down A Ton Of Money
College tennis players are unable to accept prize money as a condition for maintaining their amateur status, which means Brooksby can't receive the $100,000 he earned for reaching the second round. However, he told the New York Times after his final-round qualifying match that he was unsure about whether he would turn pro this fortnight and collect his winnings.
