It's now a cliché to say that the events of 2020 are unprecedented, and that we feel unstuck from time itself, but early 2020 does seem of a different era. After a packed January and February, which saw a new Slam winner and two high-profile retirements, the COVID-19 pandemic threw our lives (and the tennis season) into disarray. How tennis responded tells us a lot about the sport: at times remarkably agile and resilient, and at other times inequitable, clunky, and slow. Some players shone on the court, others took the year off, and at the end of the year, there's merit in simply getting through.
