Iga Swiatek tends not to waste time in the first week of Grand Slams. When the five-time Grand Slam champion dispatched Rebecca Sramkova 6-0, 6-2 in a clean hour at the Australian Open on Thursday, Swiatek was living a habit of advancing quickly through the early rounds.

It was a year of frequent coaching changes for Raducanu. Having won the U.S. Open with Andrew Richardson, she replaced him with Torben Beltz just two months after winning the title.
