AUSTRALIAN OPEN AT A GLANCE

Seven-time Australian Open champion Serena Williams plays Eugenie Bouchard in the second round and if their pre-match comments are any indication, there’s some mutual respect there.

“She does everything well, and I really like that she doesn’t quit,” Williams says. “People write her off, and she doesn’t let that bother her. She continues to fight and do what she needs to do.” Bouchard’s ranking has dropped from a career-high of No. 5 in 2014 to 79th following a spate of injuries and poor results. Asked to comment on Williams’ strengths, Bouchard replies: “Well, it’s a long list, she’s the greatest ever. It’s just so cool that I’ll be able to share the court with her and an opportunity to see how I compare to one of the best players. Her ranking is top 20 right now, but to me she’s always basically No. 1.”

The official No. 1, Simona Halep, plays Sofia Kenin. The men’s No. 1 and six-time Australian titlist Novak Djokovic takes on 2008 Australian Open finalist Jo-Wilfried Tsonga. No. 4 Alexander Zverev plays Jeremy Chardy and 16th-seeded Milos Raonic takes on 2104 champion Stan Wawrinka.
