There was a reason because Radocano was confident of Cheng, who still finds her feet at the grass stadium and has a service that can hesitate when under pressure.
Radocano, the world number 37, also made a relatively calm progress through its first two games, fell only eight games in four groups.
However, as Radocano was found against Iga Swiatek in Melbourne and Paris, and Coco Goffs in Italy, there is a different and consistent level necessary to overcome the players in order to win is usually.
At the start of an exciting start, Raducanu pressed the Zheng service while providing rest points in its own games.
But Cheng was invented in the seventh attempt, a few rear blow below the line that was silent, which was previously expressed by their dissatisfaction after Cheng was forced to change her shoes in the middle of the match.
Radokano maintained pressure, creating an immediate opportunity to win, but the huge Cheng strikes that kept it in a critical position, rushed to infiltrate the network that delivered the first group in the first group.
Radocano left the court for a medical deadline on her back, but she benefited from the first Cheng service that disappeared after her return.
With wind interruption, Raducanu produced a series of harsh revenues to the second Zheng service and soon found itself 3-0.
But Cheng is to struggle with a break and raised its severity when needed, and it crawls forward to attack the Radocano service. Double Cheng's mistake handed over a break and fell four games in a row to close the match.
“I have improved a lot and made a lot of good work behind the scenes, but there is a lot to go to reach the next level,” Radokano said.
“They are stronger than me and they had more time to train – I need to do the same. I need to raise my level.”
Raducanu is scheduled to compete at the Grass-Court event in Berlin next week, but she said she would consult with her team before making any decisions.
