The veterans were out to prove age is just a number on day 10 of the 2017 Australian Open.

Serena Williams, aged 35, reached her 10th consecutive grand slam semifinal by beating Britain's Johanna Konta 6-2 6-3.

Williams will play Croatia's Mirjana Lucic-Baroni, who won the Australian Open doubles competition as a 15-year-old in 1998. Now aged 34, Lucic-Baroni defeated Karolína Pliskova to book her semifinal place Wednesday.

Three of the four women's semifinal slots have now been taken by players aged 34 or older.

Venus Williams -- who became the Australian Open's oldest women's semifinalist in the Open Era at the age of 36 after winning through against Anastasia Pavlyuchenkova on Tuesday -- will face Coco Vandeweghe of the U.S..

Vandeweghe is something of an anomaly in the women's draw. The 25-year-old will play in her first grand slam semifinal at the Australian Open.

In the men's draw, Rafael Nadal overcame No. 3 seed Milos Raonic Wednesday to book a date with Grigor Dimitrov in the semis. The 30-year-old is a grand slam veteran with 14 titles to his name.

Roger Federer, who turned 35 last August, has also breezed through the tournament so far. He will face Stan Wawrinka in the other men's semi.
