Wang stunned Serena Williams in the third round but the 27th seed ran out of steam against the powerful Jabeur, who fought back from a break down in the first set to win 7-6 (7/4), 6-1. Jabeur, the highest-ranked Arab woman in history -- she reached a career-high 51 last year -- is the first Tunisian woman to win a main-draw match at the Australian Open. "I'm really shaking right now, it's unbelievable, I can't describe how I feel," said the 25-year-old, who will play America's Sofia Kenin in the last eight. 

"Last time Kenin won against me so maybe it'll be my revenge," added Jabeur, who lost to Kenin last year in Hobart and retired against her in Mallorca.
