Mikhail Kukushkin and Viktor Troicki will create ATP Tour history when they play in the first-ever all-qualifier final following wins at the Sydney International on Friday.

Kukushkin eliminated the last remaining seed Leonardo Mayer, while Troicki knocked out Gilles Muller to reach Saturday's final.
The Kazakhstan world number 66 downed the Argentine fifth seed 6-4, 6-4 to reach his third ATP Tour final, while Troicki overcame Muller 6-2, 6-4.
"It's interesting. I hope I go into the record books as the winner. That would be nice," Troicki said.
"Definitely it's going to be a good final. Kukushkin is playing good tennis.
"He's really hitting the ball nice. We played few times. I know what to expect."
It is the second time that world number 92 Troicki will appear in the Sydney final after he progressed to the title match in 2011.
Troicki, who reached as high as number 12 in 2011, served a 12-month suspension for failing to take a blood test at an event in 2013. It is his first ATP final since the incident.
Initially banished for 18 months -- a sanction he disputed -- he later had the sentence reduced to one year on appeal by the Court of Arbitration for Sport.
Returning in July last year with a world ranking of 847 he is likely to move at least into the 70s after his results in Sydney.
A 10-year tour journeyman, Kukushkin has one career title from Moscow in 2013.
"It's my third final, the first one outside of Russia," Kukushkin said.
"It feels good to start the season with the final with so many wins in a row. I didn't expect that on the second tournament on the year to play in a final already."
He had a service break in each set against the Argentine and has yet to drop a set this week in Sydney.
Kukushkin also saved 11 break points, including nine in the second set -- taking him to a total of 19 saves out of 22 break points for the tournament.
The triumph extended his winning record in Sydney to seven matches after he won three times in qualifying to make the main draw.
