Bratislava, Slovakia, 8 February 2016 | AAP

Sam Stosur’s Fed Cup heroics at the weekend in Slovakia have seen the Australian join rarefied company in the process.

The world No.27 won all three matches she contested – two singles matches and the decisive doubles rubber with Casey Dellacqua – in the World Group II tie in Bratislava to book Australia a place in the World Group Play-offs in April.

Stosur’s singles wins including a tough 7-6(5) 7-5 win over world No.29 Anna Karolina Schmiedlova on Sunday, not long before her 5-7 6-1 6-2 victory over Slovak pair Jana Cepelova and Daniela Hantuchova with Dellacqua.

It cemented Stosur’s place in Australian Fed Cup history, taking her career win-loss record to 36-15.

That edged her past the likes of Evonne Goolagong Cawley, Margaret Smith Court and Dianne Balestrat and gives her more wins than all but Wendy Turnbull (46-16) and Kerry Reid (37-10).

More than that, captain Alicia Molik argues, it removes the doubts over her ability to perform in high-pressure situations.

“It just proves she’s gutsy, she’s brave and she can play under immense pressure,” Molik told AAP.

“There’s no more pressure than holding your country up, having to win two singles to keep us alive.

“And then finishing it off in the doubles as well after backing up after two big days, it’s a real effort.

“It’s a real testament to her character and the type of tennis player and person she is – she does take it all in her stride and she can handle the load exceptionally well.”
