Kyrgios proved too strong for the No. 5 seed in a 6-3, 6-2 win, and will now take on Argentine Facundo Bagnis in the semi-finals.

It's the ultimate praise a young tennis player can get - a comparison with Australia's best player of the past decade, Lleyton Hewitt.

That's exactly what Canberra rising star Nick Kyrgios has received from former doubles gun Todd Woodbridge after Kyrgios won his second consecutive Challenger Tour event on Monday.

While Kyrgios' world ranking jumped to No.152, his highest yet, the Savannah Challenger win came at a slight cost, with Kyrgios straining his adductor.

It forced him to withdraw from the Tallahassee Challenger, which started on Tuesday, and instead he'll head to  Munich to continue his  clay season - hopefully culminating at the French Open.

Woodbridge said the ability to return from injury in form was rare and he was very impressed with the way Kyrgios had hit the ground running.

It was something the 16-time major doubles winner said he'd struggled with during his own career, but something Hewitt had been able to do as well as anybody.

"It's the sign of a quality player that can come back so quickly from a break and find form," Woodbridge said.

"As a trait, it's an excellent one to have.

"If you look at Lleyton Hewitt's career, he's always had that ability to come back and win matches.

"It's not that easy, that's one of the hardest things you can do."

Woodbridge felt the back-to-back wins had Kyrgios in the box seat to gain Tennis Australia's wildcard for the French Open, which would see the 19-year-old return to the scene of his victorious Grand Slam debut where he beat former world No.8 Radek Stepanek in the first round.

He said Kyrgios had clearly outgrown the Challenger Tour and would now have to re-plot the rest of his year to focus on ATP World Tour events.

Over the next 12-18 months Kyrgios would need to establish himself in the professional ranks and leave wildcards behind.

"His next step is to knock on the door and say, 'This is me qualifying at [world] tour level'," Woodbridge said.

"So a young player will then have to start adjusting their schedule on the way up.

"Then he won't be needing wildcards, he'll have cemented himself and be direct acceptances [into tournaments].

"I think within the next 12-18 months [his goal is] to be inside the top 100 well and truly so he can choose a schedule and stick to it."

Kyrgios has struggled with injury over the past six months, only recently returning from an elbow injury, but was philosophical about missing Tallahassee.

"It's unfortunate, I've had a really good couple of weeks playing well and I was really excited to play here," he said.

"I'll be hanging out and watching the tournament for the next couple of days.

"I want to get healthy again for the French Open.

"I'm just going to relax a bit and get to the gym if I can. There are a couple of Aussies playing, so I'll get behind them."
