Roger Federer erased seven match points to reach semifinal on Tuesday and stated with a smile while on court-interview " I believe in miracles".

Roger Federer gave the greatest Houdini performance of his career to move on semi-finals on Tuesday which happened after 22 years on Tour. The third seed eradicated seven match points to achieve a stunning 6-3, 2-6, 2-6, 7-6(8), 6-3 win up Tennys Sandgren in an instant classic. 

Anyhow, the 38-year-old survived this match and controlled to exceed his more primal escape in incredulity."Gotta get lucky sometimes, I'll tell you that," Federer stated Jim Courier after the match. "I think I got astonishingly lucky today."I don't deserve this one, but I'm still standing here, and I'm extremely happy."

As the match moved on, I began to feel better and just tried to play. I believe in miracles. There could be rain… Just let him finish me off in style, and he didn’t do that.

Federer stated his groin and leg ailed him, but he never more thought of leaving. His body was "stiff and tight," but if Sandgren was to win, he desired his competitor to destroy him off properly.

"The most useful of when it's a groin is that you go off the court, and no one knows what it is."What's next for Federer? For one, he'll face Novak Djokovic or Milos Raonic on Thursday night."The draws don't get any more difficult."Real, but as Federer said, he's still playing tennis in Australia—not that Tennys—rather than skiing in Switzerland.

Next up for him is second-seeded Serbian Novak Djokovic or No. 32 seed Milos Raonic of Canada. Federer trails Djokovic 23-26 in their rivalry and has dropped their past three matches in Melbourne, all of which took place in the semi-finals (2008, 2011, 2016). The Swiss leads Raonic 11-3 in their series and won their lone clash at this event in 2013.

”The draws are not getting simpler. But I’ve got the next days with nothing to do… You do feel better and you just never know. With these lucky escapes, you might play without expectations as you know you should be skiing in Switzerland… Might as well make the most of it!"
