OTHER KEY DAY ONE MATCHES

JAMES DUCKWORTH (Aus) v 2-RAFAEL NADAL (Esp)

ROD LAVER ARENA — DAY: Duckworth, winning his place in the draw through last month’s wildcard playoff tournament, returns for a seventh Australian Open. It is likely to be short after drawing the world No. 2 in the first round; the 26-year-old hasn’t beaten a top-50 player in three years.

ASTRA SHARMA (Aus) v PRISCILLA HON (Aus)

COURT 7 — DAY: At least one Australian will reach the second round at Melbourne Park thanks to this pairing of happy-to-be-here locals. Sharma, a 23-year-old from WA, is in her first grand slam after defeating three higher-ranked Russians including Vera Zvonareva in qualifying. Brisbane-based Hon returns as a wildcard three years after her first effort.

22-ROBERTO BAUTISTA AGUT (Esp) v ANDY MURRAY (Gbr)

MELBOURNE ARENA — NIGHT: The tears and tributes have flowed for Murray since the well-loved Scot’s looming retirement announcement due to hip issues. The five-time Australian Open runner-up wants to get to Wimbledon for a farewell.

15-ASH BARTY (Aus) v LUKSIKA KUMKHUM (Tha)

MARGARET COURT ARENA — NIGHT: Australia’s chief singles hope begins her campaign against Kumkhum, a surprise last year in beating Belinda Bencic and reaching the third round. The Thai beat Barty in 2016 Wimbledon qualifying. Since then, Barty has blossomed into Australia’s brightest female prospect.

6-MARIN CILIC (CRO) V BERNARD TOMIC (AUS)

MARGARET COURT ARENA — NIGHT: After enduring a failed 2018 qualifying mission, Tomic has quietly put in the hard yards to return to the world’s top 100. His reward is a meeting last year’s finalist. At the Australian Open in 2010, the Queenslander let slip a two-sets-toone advantage over Cilic to lose in five sets.

3-CAROLINE WOZNIACKI (Den) v ALISON VAN UYTVANCK (Bel)

ROD LAVER ARENA — NIGHT: The popular Dane returns as a grand-slam champion and for the first time against Belgian van Uytvanck, who climbed into the top 50 last year after winning the Budapest Open.
