MELBOURNE, Australia – There were many unknowns going into the opening round of the 2021 Australian Open with a 14-day quarantine period leading up to the event. However, some of the biggest stars in tennis showed no signs of rust, advancing to the second round.
Most Interesting Match
 Denis Shapovalov (CAN) had one of the most difficult first round matches in the tournament. The 11th-seed was up against Jannik Sinner, who was on a 10-match winning streak and coming off a title run at one of the Melbourne Summer Series events.
After losing the first set, Shapovalov faced a flurry of break points in a nine-minute opening game to begin the second but held on. The Canadian built some momentum, eventually scoring his first break to level the match at a set a piece.
The pair split the next two sets as the clock ticked midnight local time. To open the deciding set, Shapovalov created an immediate break point opportunity and converted. His fifth break of the match proved to be the difference maker, as he went on to hold and eventually score a five-set victory, 3-6, 6-3, 6-2, 4-6, 6-4.
Straight Sets Sweep
 Naomi Osaka (JPN), one of the tournament’s favorites, made quick work of her opponent, needing just over an hour to advance. Osaka’s first serve percentage was an impressive 81%.
Stan Wawrinka (SUI) began his quest for a 2nd Australian Open title with a straight-set victory. The 2014 champion never faced a break point, winning 88% of his first serve points, to advance, 6-3, 6-2, 6-4.
After taking nearly a year off from tournament competition due to the global pandemic, Nick Kyrgios (AUS) returned to his home Slam, putting on an entertaining performance for those fans in attendance. Underhand serves, between-the-leg shots, flashy drop shots, and a magnitude of aces and winners were on display in his 6-4, 6-4, 6-4 victory.
- Playing as the aggressor the majority of the match, Shapovalov recorded 62 winners, more than double Sinner’s 26.
- Osaka’s win streak extends to 15, including 8 straight at majors.
- Canadian qualifier Rebecca Marino (CAN), who came out of retirement in 2018, won her first Grand Slam match in 10 years.
- Marton Fucsovics (HUN) recorded the longest opening round, winning in 4 hours, 12 minutes.
- Jessica Pegula (USA) scored the biggest upset of the first round on the women’s side, taking out 12th-seeded and two-time Australian Open champion Victoria Azarenka, the highest seed to fall so far.
- Along with Pegula, Radu Albot (MDA) (def.  Roberto Bautista Agut), Olga Danilovic (SRB) (def.  Petra Martic), Kaja Juvan (SLO) (def.  Johanna Konta) also upset seeded players in the first round.
- 20-year-olds Danilovic and Tomas Machac (CZE) picked up their first career Grand Slam victory
