Australia Davis Cup captain Lleyton Hewitt is bullish over the fitness of star pair Nick Kyrgios and Bernard Tomic heading into the upcoming tie against the United States.
Hewitt and Co. will face the USA in the first round of the Davis Cup in Melbourne, starting Friday, with Kyrgios nursing back and hip issues, while Tomic is battling wrist soreness.
Kyrgios retired hurt against Stan Wawrinka in the semi-finals of the Dubai Tennis Championships on Friday.
Tomic complained about his wrist following Saturday's loss to Dominic Thiem in the Abierto Mexicano Telcel final.
Hewitt, however, is confident the duo will be fit to play at Kooyong.
"Both Nick and Bernie are playing extremely well at the moment. The biggest thing for them is to get their bodies as close to 100 per cent physically [as they can]," Hewitt said.
"They've had the matches, they're confident, they feel good out on the court at the moment and they back themselves on the big points.
"That's why it's important for them now to more mentally prepare than anything. They've beaten quality players over the last couple of weeks.
"It's more about just managing those two now because they've had such a busy workload ... and just about getting a bit of a feel for the grass.
"I'm comfortable for both those guys that their games naturally suit grass, as well, so it's not going to take very long."
