Serena Williams kept her record-breaking Grand Slam dream alive Wednesday by beating Johanna Konta to make the Australian Open semi-finals, where she will meet fellow veteran Mirjana Lucic-Baroni. The American joined sister Venus in the last four after stepping up a level to oust the dangerous Briton 6-2, 6-3 on Rod Laver Arena and end her nine-match winning streak.
