Jenson Brooksby on the rise with ATP run in Newport

It's not bad winning the smaller events, but now Jenson Brooksby wants to take it to the next level.

The 20-year-old American scored the third tour win of this career—and his second this week—at the ATP Newport event, defeating Denis Kudla in the second round.

"I want to prove that I can do the same on the ATP events as I have in the Challenger events," Brooksby was quoted as telling press.

On the Challenger tour this season, he has been on a roll—winning an event in South Africa, reaching a final in Cleveland, then winning in Tallahassee and Orlando. He also won three qualifying contests at the French Open before falling in the first round to Aslan Karatsev.

Getting some ATP wins at Newport has been a welcome next step.

WATCH: Jack Sock spoke with Blair Henley after his victory in Newport.

"I knew that I had the level, I believe in my skills, but it takes more than that... this has given me confidence that I can compete with the best," he said.

"I’m excited to play some more. I try to treat every match the same. I try to focus on myself and take care of the rest."

Brooksby did not play qualifying at Wimbledon, taking time off to rest his shoulder, but is happy to finally get some play on grass.

"Grass can be the best surface for my game style," he said. "It’s the ball staying lower in general. On clay, it sits up more.

"My movement is good when the ball is a little lower, my footwork is good."

Brooksby is No.152 in the rankings.
