Jankovic mounted a brief regroup as her backhand winner down the line and her backhand winner crosscourt led to her break of serve to pull even once again at 4 all.
With Jankovic serving, Bartoli's extreme Seles-like return of serves continued as Bartoli would reach 30-40. Bartoli pounced upon timid serving from Jankovic and survived a six deuce game to break serve to reach 5-4 behind two backhand winners, the last of which was a huge backhand crosscourt return winner.
Seles won the Australian Open in 1991, 1992, 1993 and 1996 and could have been proud had she seen another twohander wowing the Melbourne crowd on Sunday.
In the final game of the match, Bartoli reached 15-0 after a Jankovic backhand floated just long. Jankovic requested to challenge the call but had used her last challenge earlier in the set at 2-3.
Bartoli scored her first matchpoint after striking an ace and after another Jankovic backhand would land long. And after doublefaulting, Bartolli, reentered Seles mode as she whipped a final twohanded forehand down the line for a winner to close the match 6-1, 6-4.
Bartoli screamed and raised both arms in delight after the point. Then as she blew kisses and waved to the equally delighted Melbourne crowd, Bartoli was serenaded with loud applause and whistles.
Jankovic came under criticism last year after she reached the top ranking as she is the only top ranked WTA Tour player never to win a singles grand slam title.
Bartoli aged 24 and ranked 17th, is known for her unorthodox but very powerful two handed forehand and backhands which were inspired by Seles.
The Frenchwoman may also be remembered for reaching the 2007 Wimbledon singles final. In route to the final, Bartoli had upset Jankovic, Shahar Peer of Israel and the then world number one Justine Henin of Belgium.
It was my first time in Rod Laver Arena, Bartoli said. I think I just played amazing today. The last game of the match she was really tough. I served so well the last game and I'm so happy. I'm just so happy about today.
