We're checking in at the midpoint of the 2018 Australian Open, an altogether different experience than last year. The topic of most interest to us is Novak Djokovic's alleged call for a players' union at the recent ATP all-player meeting, and the questions this raises for the sport. We grapple with the coverage that openly ridiculed Djokovic's actions, the potential ways that a union can change tennis for the better, and the inevitable gender politics embedded in the discussion. But first, we recap some of the biggest moments of the first week, including Naomi Osaka's big night, the Halep-Davis marathon, Tsonga's thrilling 5-setter against Shapovalov, and Kerber's convincing beatdown of Maria Sharapova.
