Serena Williams overcame a spirited challenge from fellow American Madison Keys to become the oldest Australian Open finalist in the open era on Thursday.
Williams recovered from a break down in the opening set and saw teenager Keys save seven match points before eventually securing a 7-6 (7/5) 6-2 win in an hour and 24 minutes on Rod Laver Arena.

Novak Djokovic has secured his 25th career Grand Slam semi-final after a convincing straight sets victory over Milos Raonic.
The four times Australian Open winner will face Stan Wawrinka, who earlier defeated Kei Nishikori.
World number one Djokovic needed a tie break to claim the first set, but went on to break his 24 year-old Canadian opponent early in the second and third sets to claim a 7-6 (7-5) 6-4 6-2 victory.
Eighth seed Raonic, who pushed deep at the grand slams last year, was supposed to offer the first real test for the top-seeded Serb but was completely outclassed under the lights at Rod Laver Arena.
It was the first time Djokovic has booked his place in the Australian Open semi-finals without dropping a set since 2008.

Andy Murray saw off Nick Kyrgios in three sets to progress to the Australian Open semi-finals where he will face Tomas Berdych.
The Scot took control early on in the match, winning the first set 6-3.
Kyrgios fought back, but lost out in a tie-break to Murray in the second.
Once Murray broke to make it 4-2 in the third, the British No.1 had almost sealed the victory, eventually taking the final set 6-3.
Rafael Nadal refused to make any excuses after his record-equalling winning streak over Tomas Berdych came to a comprehensive end in the quarter-finals of the Australian Open on Tuesday.
Berdych won three of his first four meetings with Nadal but had not tasted victory over the Spaniard since 2006, his 17 straight defeats equalling a record in the open era.
However, the 29-year-old Czech picked the ideal time to end the sequence with a stunning 6-2 6-0 7-6 (7/5) victory on Rod Laver Arena and has yet to drop a set in the championship.
I didn't play with the right intensity, with the right rhythm, and the opponent played better than me.
It is a day that I just can congratulate my opponent. It is obvious that I needed something more to be more competitive, as I did in the third set. The third was the right set, the right game that I have to play.
But is obvious that before I didn't play with the right confidence, with the right intensity, losing court (position), playing very short. I make him play very easy. So you cannot expect to win matches in quarter-finals of a grand slam helping the opponent to play well.
Andy Murray says he doesn't know if will wear full Scottish attire for his wedding.
The tennis star, who beat Grigor Dimitrov at the Australian Open on Sunday, is set to marry long-term partner Kim Sears in October.
Murray was quizzed on the subject by on-court interviewer Hamish McLachlan following the Scot's victory over Grigor Dimitrov on Sunday.
Chief among McLachlan's interests was whether Murray would be wearing a suit or a kilt on his wedding day.
Murray, clearly taken a little aback by the question, replied: "I think... I am going to have both options and see what I feel like in the morning when I wake up."
Traditionally Scots do not wear any underwear beneath their kilts.
When quizzed on whether he would be wearing a kilt "properly", Murray replied: "Yeah, obviously proper kilt, yeah."
When asked if that meant he would be going "freeball" - i.e. without any underwear - Murray replied with a smile: "Exactly."
Andy Murray has made it through to the fifth round of the Australian Open after a testing encounter with Grigor Dimitrov.
The Scot won the opening set, but lost the second on a tie-break.
After cruising the third set, it looked like he was setting himself up for an easy victory, but Bulgarian went 3-0 up in the fourth, but Murray fought back strongly to win the set.

Andy Murray has set up a mouth-watering clash with Grigor Dimitrov and a chance to avenge his defeat at Wimbledon after hammering Portugal's Joao Sousa 6-1 6-1 7-5 to reach the fourth round of the Australian Open on Friday.
The Briton had his Wimbledon title defence ended by Dimitrov in the quarter-finals last year and will face the rising Bulgarian after he prevailed in a five-set dog-fight against Marcos Baghdatis.
"It will be a tough match obviously," sixth seed Murray told reporters.
"He's played well in the slams the last year or so. Yeah, he's obviously a talented player. You know, he's one of the young guys trying to make a breakthrough, so he'll be motivated.
"Hopefully I can play a good match and make it tough for him."
