Seven-time Grand Slam champion and returning hero, Justine Henin, beat giant-killer Nadia Petrova in a close quarter-final in which the Belgian came through 7-6, 7-5. The "Roger Federer of women's tennis", as Todd Woodbridge labelled her, is looking better with each match, and will face Chinese Zheng Jie, who beat Maria Kirilenko, for a place in the final.
Andy Roddick got awfully lucky in his last 16 match with Fernando Gonzalez when the most outrageous umpiring decision saw Mr. Molina fail to replay a challenged point when the Chilean had a shot on the questioned ball. Roddick was resultingly awarded the point, which just happened to be game point, break point and set point at a crucial moment in the match.
He wasn't so lucky against Cilic, when after coming back from two sets down, the young Croat blew him away 6-3 in the fifth.
The amazing run of Marin Cilic has seen him conquer Stanislas Wawrinka, Juan Martin Del Potro and now Andy Roddick, en route to his first Grand Slam semi-final.
There, he will meet Andy Murray who was on top of Nadal from the start, taking the first set 6-3 and then winning the 2nd set tiebreak in a largely impressive performance against the second best player in the world. Murray had an answer to everything Nadal came up with, and with the Briton leading 3-0 in the third, the Spaniard conceded the match, being troubled with yet another knee injury which flared up in the 2nd set.
However, Murray should be cautious of the dangerously impressive Cilic, who could yet spring another surprise at Melbourne Park.
