Novak Djokovic beat Daniil Medvedev, 7-5, 6-2, 6-2, to keep his Australian Open dominance intact — nine finals, nine championships.

• Why it matters: Djokovic now has 18 Grand Slam singles titles, two away from the men's record held by Roger Federer and Rafael Nadal. Only Nadal has won a single Slam more often (13x at Roland-Garros).
• The big picture: The Big 3 have won 58 of the last 70 Grand Slams — and 15 of the last 16. Since Federer's first Slam in 2003, they've lost back-to-back titles just once (2016 Wimbledon and U.S. Open).

Looking ahead: Djokovic, 33, has spent his career in the shadow of Federer, 39, and Nadal, 34, as the de facto bronze medalist on the all-time podium.

• And yet, considering he's the youngest and currently the most dominant (5-0 in his last five Australian Opens and Wimbledons), he seems destined to win the most Grand Slams of the three.
• The bottom line: The Big 3 are a gift from the sports gods. How often do we get to watch a G.O.A.T. debate play out in real-time like this?

Naomi Osaka cruised past Jennifer Brady to win her fourth Grand Slam, adding to the 2018 and 2020 U.S. Opens, plus her 2019 Australia title. The 23-year-old sensation has yet to lose a major final.

"We talk about the depth of women's tennis ... But something is shifting now, and it's all about Naomi. ... She's breaking away from the pack."

BioReference Laboratories, Inc. has been a key cog in the sports-amid-a-pandemic machine, providing tailor-made, COVID-19 testing solutions for most major American sports leagues, Axios' Jeff Tracy writes.

• Year founded: 1981
• Parent company: OPKO Health
• Overview: One of the largest full-service, specialty laboratories in the U.S., averaging 50-60,000 PCR tests per day.

The state of play: BioReference works mostly with non-sports clients (they've tested New York City public schools, for example). But the company's athletic footprint is unmatched over the past year.

• Bubbles: NBA, NHL and MLS bubbles; Winter X Games; NBA G League bubble.
• Non-bubbles: 2020-21 NFL season; current NBA and NHL seasons; USMNT and USWNT.
• Fan testing: Bills home playoff games; NBA teams hosting fans this season.

Between the lines: Each client requires a custom solution. So while BioReference has become the de facto "sports testing partner," they've provided vastly different services from league to league.

• NFL: BioReference performed 1.23 million tests last season, comprising 5,000 people tested daily for seven months, per OPKO's Q4 earnings call. They tested teams at their facilities, then delivered the tests to nearby labs, which returned results within 24 hours.
• NBA: Roughly 100 BioReference employees lived in the Disney bubble and administered tests to players, which were then driven 75 minutes away to a lab in Melbourne, Florida.
• Fans: Testing fans ahead of the Bills' playoff games presented a new challenge. "We had to build the IT infrastructure so fans could go to the website, pick a time, schedule their test, show up, get tested in five minutes and have the result on their phone within 24 hours," executive chairman Jon Cohen tells Axios.

What's next: BioReference has an agreement with MLB to be their testing partner for the 2021 season, which begins in less than five weeks.

West Ham United beat Tottenham, 2-1, on Sunday to move into fourth place in the Premier League, Jeff writes.

Why it matters: The 126-year-old club has the best record among the six London-based clubs in England's top flight:

• West Ham: 45 points (fourth)
• Chelsea: 43 (fifth)
• Tottenham: 36 (ninth)
• Arsenal: 34 (10th)
• Crystal Palace: 29 (14th)
• Fulham: 22 (18th)

The backdrop: West Ham have never finished better than fifth in the Premier League, and at this point last season, they had just 24 points and were the worst of the London clubs.

• Founded in 1895 as Thames Ironworks by and for the shipbuilders in the neighborhood, they became West Ham United in 1900.
• Their fans were once among the most notorious hooligan outfits in England, engaging in a bitter, decades-long rivalry with Millwall (as fictionally portrayed in 2005's "Green Street Hooligans").

• 🇬🇧 Premier League: In other EPL news, Everton beat Liverpool, 2-0, for their first Merseyside Derby victory at Anfield since 1999.
• 🇮🇹 Serie A: Inter beat rival AC Milan for the sixth time in the last seven matches, as the two Milanese clubs remain atop the league.
• 🇩🇪 Bundesliga: Eintracht Frankfurt, who haven't lost in league play since Dec. 11, beat first-place Bayern Munich to move into a tie for third.
• 🇺🇸 USWNT beat Brazil, 2-0, to improve to 2-0 in the SheBelieves Cup. Next up: Argentina on Wednesday.

No. 3 Michigan beat No. 4 Ohio State, 92-87, on Sunday in the best game of the men's college basketball season, Jeff writes.

• And in women's hoop's, No. 11 Michigan also took care of No. 15 Ohio State, 75-66, to improve to 13-2.
