Serena Williams reached her 10th consecutive Grand Slam semifinal, and kept her bid alive for a record 23rd major title, with a 6-2, 6-3 win over Johanna Konta at the Australian Open on Wednesday. Her opponent in the semifinals, Mirjana Lucic-Baroni, who beat fifth-seeded Karolina Pliskova 6-4, 3-6, 6-4, had a much longer wait to get back to this stage at a major – nearly 18 years.
