John Millman has continued his remarkable run at the Japan Open by beating American Reilly Opelka 6-3 7-6 (7-4).
The world number 80 had to save three match points in qualifying just to make the main draw, while he also fell a set down in his last-32 meeting with Adrian Mannarino.
However, he has now won eight consecutive sets to reach his second ATP Tour final, neutralising the massive serve of the 211cm American.
“That was a pretty good match. It’s always difficult playing against someone like Reilly, who has got such a massive serve. I was really happy to take the few little chances I had and took care of my own service games pretty well,” Millman said after the match.
“Managing to get through to play a final in Tokyo, that’s pretty special for me.
“When he’s got such a big serve and they’re coming down so quick, even if you are leaning towards the right way, it’s still very tough to put that ball back,
“Really happy, really nice to also get off in straights.”
He will now face Novak Djokovic, who defeated David Goffin in straight sets on Saturday to reach his 110th career ATP final.
The world number one needed one hour and 29 minutes to record a 6-3 6-4 triumph over the third seed, meaning he is still yet to drop a set in his first appearance at the tournament in Tokyo.
Djokovic has dropped his own serve just twice in four matches so far, albeit he was forced to save four break points against Goffin, who was crowned champion at the event two years ago.
However, the top seed recorded early breaks in each set and won 87 per cent of points on his first serve.
Even when there was an occasional glimmer of hope for Goffin, sublime defence helped Djokovic get out of trouble.
See you tomorrow, @DjokerNole
