Australian qualifier Jason Kubler faces a restless night after being left stranded one tantalising game shy of a coveted place in the Wimbledon third round.

A late-afternoon downpour forced the suspension of play for the day with Kubler leading fellow qualifier Dennis Novak 6-3 6-4 5-4 on court 16 on Thursday.

He’d just broken the Austrian and was about the serve for the match when the heavens opened, prompting a wry smile from the self-confessed “Australian tennis battler” as he gathered his gear and scurried for cover.

If Kubler can hold his nerve – and serve one more time – when the match resumes on Friday, the 29-year-old will have earned more money in the past week than he has all season.

A place in the last 32 at the All England Club is worth a minimum of Stg 121,000 ($A213,000).

Kubler would earn even more if he gatecrashed the last 16 with another victory on Saturday over either Jack Sock or Maxime Cressy.

Sock was leading Cressy 6-4 6-4 when the all-American second-round affair was also suspended.

It would be nothing less than Kubler deserves following an inspired comeback from the one-time world No.1 junior, whose career has been cruelly dogged by injury, including five rounds of knee surgery.

With 17 wins from his past 19 outings, Kubler is finally back in the world’s top 100 with seemingly his best work to come.

The Queenslander was Australia’s last man standing at the French Open after also winning three qualifying encounters just to make the main draw, like he did last week at Roehampton to seal his Wimbledon spot.

Now he’s yet to drop a set this week, having taken out British seed Dan Evans in round one without dropping one service game.
