Here's a short story:

(CNN)At the 1994 U.S. Open, John McEnroe said he would commentate on his head if Jan Siemerink won a fourth-set tiebreak after falling behind 6-0 to fellow Dutchman Richard Krajicek. 

Guess what? It happened. 

Siemerink claimed the next eight points and McEnroe did as he promised in a later match at the season's final major. 

No commentators were believed to have said something similar when Stan Wawrinka trailed Guillermo Garcia-Lopez 5-0 and 6-2 in a fourth-set tiebreak Monday at the Australian Open -- and lucky for them. 

Just like Siemerink, Wawrinka did the almost unthinkable and pulled off a great escape. 

The defending champion at the year's opening grand slam saved five set points in the tiebreak to close out the encounter against the Spaniard 7-6 (2) 6-4 4-6 7-6 (8) and advance to the quarterfinals. 

"Losing 5-0 was a bad start to the tiebreak," Wawrinka, upset by Garcia-Lopez at the 2014 French Open, told reporters. "At 6-2 I knew it was close to come back because I had the wind with me. 

"I had to focus on every point. I knew if I was going to come back (to) 6-5, (he) was going to get nervous. Just focused point after point." 

Wawrinka is flying the Swiss flag after Roger Federer's surprising loss to Andreas Seppi in the third round and the world No. 4 will have to maintain, or increase, his level if he is to continue his winning streak at Melbourne Park. 

Wawrinka's quarterfinal opponent, Kei Nishikori, beat the 29-year-old in the last eight in September en route to making the final at the U.S. Open.  (End of story)
