What a difference a year makes. This time in 2021, Barbora Krejcikova was ranked 66th in the world but is now up to fourth and third in the live rankings. Now she takes on Madison Keys in the Australian Open quarter finals. The winner of this match takes on either top seeded Ashleigh Barty or Jessica Pegula in the last four. Before this year, Krejcikova (who can move up to second in the rankings if winning this match) had never been past the second round in this tournament. More success has come in the doubles where she is ranked second in the world. Winning the French Open singles title last year was the highlight of a breakthrough year for her in the singles ranks. This year began with her making the final of a tournament in Sydney, losing to Paula Badosa. Only one set has been dropped by her on the way to this quarter final and in the last round, Krejcikova dropped just four games in beating Viktoria Azarenka.
Six years ago, Madison Keys was as high as seventh in the world rankings. On January 10 of this year, the American was down to 87th but has been in top form since then. Keys beat Elina Svitolina, Coco Gauff and Allison Riske, in winning the second Adelaide International tournament. That was the first event she'd won since 2019. At the start of the Australian Open, she was up to 51st but is now 35th in the live rankings. To reach the quarter finals of this Australian Open, Keys has had four wins, including beating former champion Sofia Kenin and in the last 16, Paula Badosa (recent victor over Krejcikova) for the loss of just four games. This looks like being a close match, go for both players to win a set.
