Ben and Tumaini had a lot to catch up on this week, so we are splitting this episode into two parts. The first part, here, begins with the Court of Arbitration for Sport issuing a radical reversal of the first decision on Simona Halep's positive test, which means Halep can return to tour immediately. We don't have all the answers yet, but what does the dramatic disparity between the two decisions say about the dysfunction of the tennis anti-doping system? In the second part of this episode, we discuss Andrey Rublev getting defaulted from his semifinal in Dubai for berating a line judge, and how that moment should be instructive. Thanks for listening!
