Nottingham, UK, 15 June 2014 |

Nick Kyrgios has won his fourth ATP Challenger title by beating Sam Groth in an all-Aussie Nottingham final on Saturday.

The victory guarantees the 19-year-old a wildcard into the main draw at Wimbledon.

In further good news for Australia, Jarmila Gajdosova reached the women’s final with a 6-4 6-4 win over Andrea Hlavackova of Czech Republic.

Krygios beat Groth in a big-hitting, rain-delayed final by the scoreline of 7-6(3) 7-6(7) at the grasscourt event.

Players were forced off court deep in the second set with Groth serving to stay in the match down 5-6.

When they returned, Groth managed to force the set to a tiebreak and make Kyrgios work extremely hard for victory before the teenager finally triumphed on his fifth match point.

“Wow!! Pleased to get through that!! Always nice to get a call on court from the Wimby Ref saying I have an MD wild card to @Wimbledon! #BOOM,” he tweeted.

Meanwhile, Gajdosova will take a seven-match winning streak into the Nottingham women’s final against Swiss Timea Bacsinszky.

The former world No.25 won three matches in qualifying and then four in the main draw to reach her first final of any kind since winning the WTA title in Hobart in January 2011.

Should Gajdosova win, she would also be granted a Wimbledon main draw wildcard.
