The Czech's Commanding Performance
The contest presented an possibility for the British player to prolong her remarkable campaign, but her opponent demonstrated why she is much-touted as a promising talent.
The Czech player displayed her clean and devastating shot-making abilities from the outset, dictating points with forceful shots from each side, aggressively moving forward the net and imposing her style throughout the match.
Sonay's Solid Effort
Although losing the first set in somewhat comfortable manner, Kartal had performed well at all, which further emphasized the difficulty she encounters when playing at the elite level.
She defended well, making few errors and demonstrating her resourcefulness with low backhand shots and numerous superb passing shots.
She also sought opportunities to attack with her heavy forehand, but there is only so much against an confident opponent who could produce greater ball speed and power.
Final Set Battle
Kartal continued her solid level in the second set and capitalized when Noskova's level briefly dipped, earning an service break in the final set.
Nevertheless, after dropping her opening service game, the Czech player established a dominant rhythm, surrendering just minimal points for the remainder of the set.
Her success rate on 79% of her initial serves and produced multiple aces, with her confidence behind the serve carrying over to the remainder of her game as she controlled Kartal in the last moments to earn the most important final four of her early career.
Tournament Context
She will be the only non-American player in the China Open last four, awaiting the successful player of the last-eight between Pegula and Navarro.
In the other semi-final, Coco Gauff and Anisimova will resume their competition from the junior circuit.
Positive Developments for Kartal
Despite the loss, Kartal will leave Beijing having achieved several improvements in her career.
After climbing as high as the 44th position in the world rankings earlier this year, the removal of points from her maiden WTA title in Tunisia had caused her fall to as low as No. 82 last month.
Following this performance, she will climb to No. 60 and overtake Francesca Jones and Katie Boulter to become the UK's number two.
Long-term Potential
The effect this tournament will have on her confidence and how she is perceived by the other players is particularly notable.
Given her smaller 164cm stature, Sonay will consistently be vulnerable against strong ball strikers like Noskova, who can simply outhit her on their good days.
Nevertheless, she is also proving that her competitors must earn their successes and perform at a sufficiently high level to overcome her.
Through her superb fitness, her sharp and powerful forehand, her versatility of shots and her composure in difficult moments, the British player has numerous assets in her toolbox to disrupt skilled opposition.
With a few weeks remaining in the competitive year, her immediate goal is to maintain this high level until the end.
