Angelique Kerber upset Serena Williams 6-4, 3-6, 6-4 to win the Australian Open title on Saturday, ending the six-time champion’s unbeaten streak in finals here and winning a major title for the first time. Williams was an overwhelming favorite at Melbourne Park, where she had won all six previous times she’d reached the final, and was trying
to equal Steffi Graf’s Open-era record of 22 Grand Slam singles titles. For the second time in as many majors, though, she fell short. Williams won the Australian Open, French Open and Wimbledon titles last year before losing to Roberta Vinci in the U.S. Open semifinals. She was so close to a calendar-year Grand Slam in 2015, but now has no chance to push for that honor in 2016 after losing the first major of the year.
