Thanasi Kokkinakis does not yet have a set date for returning to the ATP World Tour, said Lleyton Hewitt.

The 20-year-old Australian underwent shoulder surgery a year ago and played just one match this season before he tore his pectoral muscle and was sidelined again.

Hewitt, who is the Davis Cup captain for Australia, told AAP News that Kokkinakis is still having “ups and downs” as he returns to full fitness.

“I’m not 100 percent sure when he’ll probably be back,” Hewitt said. “He probably thought it was going to be maybe a three-, four-month injury and it’s turned into a whole year now.”

His comeback was intended to begin at the Australian Open wildcard playoffs, but may be delayed until the ATP event at Brisbane.

Hewitt said he sees it being a while before the former junior champ regains his form, but added that Kokkinakis still has the ability that turned him into one of the tour’s top young up-and-comers before the injury.


“I don’t think we can come back and expect him to pick up where he took off,” Hewitt said. “I think it’s going to be a longer-term process.

“But he’s got so much talent. He’s such a good kid.”

Having reached a career-high No. 69, Kokkinakis is now unranked on the ATP World Tour.
