Results

Caty McNally def. Sam Stosur (AUS)
6-1, 6-4

Was this the last time we'll see Sam Stosur grace the courts of her home Grand Slam? The 35-year-old was defeated by 18-year-old American Caty McNally under the roof of Melbourne Arena, but didn't go down without a fight.

The veteran Aussie, who has now bowed out in the first round of the Australian Open for five straight years, looked to be well out of depth when McNally raced to a 6-1 lead. But Stosur, after being broken early in the second, rallied back to have the match on serve before McNally broke again in the 10th game of the second to win the match 6-1, 6-4. The stat lines were damning for Stosur, who racked up 39 unforced errors to her opponent's 22, while she could only manage to take advantage of 1/12 break point opportunities to McNally's 5/12.

Matteo Berrettini (8) def. Andrew Harris (AUS)
6-3, 6-1, 6-3

The No. 8 seed Berrettini never looked threatened by Australian wildcard Andrew Harris. The Italian opened up a 3-0 lead right off the bat in the first set, and dropped just one game in the second set to come away with a comfortable win in just under two hours.

Guido Pella (22) def. John-Patrick Smith (AUS)
6-3, 7-5, 6-4

JP Smith had the opportunity to take a big scalp early at this year's Australian Open, but the 22nd seed Guido Pella proved too strong, winning in straight sets. After losing the first set in 35 minutes, the Aussie looked much more settled in the second, but couldn't take advantage - falling 7-5. The Argentine didn't look back after that, winning the third set comfortably to advance to the second round of the Australian Open for just the second time.

Ann Li def. Lizette Cabrera (AUS)
7-6, 7-6

It was a straight sets win for the American qualifier Li, but it was anything but a walkover. Lasting 1 hour and 58 minutes, both sets went to tiebreaks, with Cabrera saving five match points in the second before a rain delay held up proceedings. Following the brief break, Li came out, hit two winners and the match was done. It was an entertaining affair if nothing else.

Aussies in action

Marc Polmans (AUS) vs. Mikhail Kukushkin
Rescheduled due to rain

It might come as a surprise to some that Mikhail Kukushkin is still doing the Grand Slam rounds; the 32-year-old hasn't had much luck in Melbourne over his career. Aside from a surprise fourth-round appearance back in 2012, he's been knocked out in the first round in every other Melbourne Park appearance. That fact won't be going to Polmans' head, however. The 22-year-old Aussie only made his Open main draw debut last year and fell to Denis Kudla in what really was a five-set epic. Can the Melbourne boy get his first Slam match victory on Monday? This may be his best shot.

John Millman (AUS) vs. Ugo Humbert
Rescheduled due to rain

Crowd favourite Millman makes his 2020 Australian Open debut against Frenchman Ugo Humbert. Humbert has already made waves this summer by upsetting John Isner and Benoit Paire in Auckland for the ASB Classic title. Millman is a battler and rises to the occasion when playing on home soil, but the 21-year-old Frenchman isn't an easy first-round match-up.

Jordan Thompson (AUS) vs. Alexander Bublik
Rescheduled due to rain

Could Thompson be somewhat of a late bloomer? Ranked No. 65 in the world, Thompson is coming off a career-best year, in which he won four Grand Slam matches and made the last 16 of the Miami Open. Last year in Melbourne, he accounted for Feliciano Lopez in the first round -- no mean feat -- before falling to Andreas Seppi. Thompson faces mysterious Kazakh Alexander Bublik (ranked just above him at No. 55) in the first round, and will be hoping the home court factor will give him the edge.

Max Purcell (AUS) vs. Jannik Sinner
Rescheduled due to rain
