A quick look at the Australian Open:
LOOKAHEAD TO TUESDAY
Serena Williams goes up against Simona Halep in the quarterfinals — their 12th meeting on tour in a matchup that dates to a decade ago. Williams leads the series 9-2, but Halep won their most recent showdown, 6-2, 6-2 in the 2019 Wimbledon final. That was one of four consecutive defeats in Grand Slam title matches for Williams as she chases her record-tying 24th major singles trophy. Naomi Osaka, whose three major championships include the 2019 Australian Open, goes up against Hsieh Su-wei, who at 35 is the oldest woman to make her Grand Slam quarterfinal debut. Hsieh hadn’t won a match against a Top 10 opponent until 2017, but now has seven such victories. Four of their five previous matches have gone three sets; Osaka is 4-1 head-to-head. In the men’s quarterfinals, eight-time Australian Open champion Novak Djokovic carries an abdominal muscle injury into his match against 2020 U.S. Open runner-up Alexander Zverev. Djokovic holds a 5-2 edge over Zverev overall, including winning the last four in a row they’ve played. Djokovic seeks his 31st career appearance in a Grand Slam semifinal as he chases title No. 18, which would move him within two of rivals Roger Federer and Rafael Nadal. The other men’s match is 18th-seeded Grigor Dimitrov against 114th-ranked Russian qualifier Aslan Karatsev, who is making his Grand Slam main-draw debut at age 27.
