Aryna Sabalenka

2018 closing comment: Aryna Sabalenka was arguably the biggest improvers in 2018, rocketing up the rankings with her bold and aggressive style of tennis. The sky is the limit for Sabalenka, she has already proven that her best is capable of beating anyone, yet she still has a heap of room for improvement in her game.

Rank 11

Petra Kvitova

2018 closing comment: Petra Kvitova is back. Kvitova won 5 titles in 2018, when she was on she was almost unstoppable, showing that her best is still as good as it gets. Inconsistency is still an issue for Kvitova and probably always will be, Kvitova really struggled at the Grand Slams in 2018, no doubt 2019 will see Kvitova largely focus on performing well in the 4 Grand Slams. If Kvitova gets things together at a major, she is still a threat and chance to win a third major. 

Rank 12

Madison Keys

2018 closing comment: Madison Keys continues to tease but ultimately stumble at the final hurdle. 2018 was another season of near misses for Keys, Keys made the quarter-finals in Melbourne, the semi-finals in Paris and New York but in all 3 of those matches she was fairly comfortably beaten in straight sets. Keys has struggled in the last few years in the biggest matches, especially against counter-punchers. Keys still remains injury prone and probably needs to sort out those issues before she can go all the way at a Grand Slam.  

Rank 13

Johanna Konta

Johanna Konta shot to prominence at the 2016 Australian Open with a run to the semi-finals. Konta has not looked back since, narrowly missing out on an appearance at the WTA Finals in 2016 and 2017. Konta has a very complete game, one of the best serves on tour, her backhand is also up there with the best. A good forehand and a tidy game at the net make Konta very dangerous. What is worth noting is that Konta also has one of the most dangerous returns of serve, coupled with her very consistent serve, she is hard to stop when performing at her best. Expect Konta to be featuring prominently at major titles for years to come.

Rank 15

Garbine Muguruza

2018 closing comment: Muguruza had her worst season in while in 2018. Muguruza consistently looked unhappy and agitated on court in 2018 and was very rarely able to find her best tennis, certainly not on a consistent enough basis. There is no doubting that Muguruza’s best level is very dangerous, she has won 2 Grand Slam titles for a reason. However, there is no guarantee that she will ever reach that level again. Time will tell…
