Lleyton Hewitt has said that some of Australia's emerging young players have big careers ahead of them after impressing at this year's Australian Open.
The former world number one joined the likes of Bernard Tomic, Nick Kyrgios and Thanasi Kokkinakis in the second round at the event in Melbourne earlier.
The 33-year-old told reporters: "I think for the most part those three guys, obviously Tomic, Kyrgios and Kokkinakis, they have big futures.
"All three guys like playing on the big stage, which is really important. I've seen that in Davis Cup now. It doesn't get much more pressure than playing Davis Cup, where you're playing for your country and your teammates as well as yourself.
"It hasn't really surprised me the last couple of days. It's great for Australian tennis. It's starting to get back like the good old days. The younger guys are coming through, There's the emergence of Sam Groth. It's exciting."
Seven Australian men made it through to the second round of the tournament, while three women are already through too.
