Rank 11

Sloane Stephens

Stephens U.S Open triumph is arguably one of the biggest Grand Slam flukes. Stephens did not win a match for the remainder of 2017 after her U.S Open victory, it will be interesting to see if she can regroup in 2018. Stephens has an exciting game, explosive speed, power and versatility.

Rank 12

Julia Goerges

Goerges has always been known for inconsistency. Goerges has the game to trouble most players on her day, however she also has the ability to lose to most players on a bad day. In late 2017 the German showed that she has the ability to play consistent quality tennis as she won two big titles in a row in Moscow and Zhuhai. The problem for Goerges is that her game will always be very hit or miss, she also lacks versatility.

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 14

Rank 15

CoCo Vandeweghe

At her best, CoCo Vandeweghe is one of the best players on tour. A huge serve and forehand combination and a good game at the net are the hallmarks of the American's game. However, the volatile American struggles with inconsistency and adaptability. Vandeweghe has shown her ability to perform on the big stage with two semi-final appearances at the Grand Slam level in 2017. With Pat Cash by her side, if Vandeweghe gets things together in 2018, she could go one step further.

Rank 16

Anastasija Sevastova

Sevastova’s comeback has been impressive. A solid top 20 player. The Latvian had some big wins in 2017, most notably her fourth round win over Maria Sharapova at the U.S Open. Sevastova has a unique game, a huge amount of variety headlined by the best backhand drop shot in the business. Sevastova’s tendency to get down on herself and lack of big weapons are her downfall.

Rank 17

Rank 18

Kristina Mladenovic

The difference between Mladenovic’s best and worst is huge. At her best, Mladenovic controls the court with her flashy, stylish tennis. However, at her worst, she is tentative and nervous, plagued with double faults. In 2017 we saw her best and her worst. Mladenovic has a versatile game, her ability and the net and touch, are unique strengths for someone with her power.

Rank 19

Ashleigh Barty

Barty is a player on the rise. A very effective first and second serve are the hallmark of her game. Solid groundstrokes, variety from the baseline and a good ability at the net make the Aussie a very complete player with great potential.
