Katie Boulter is out of the Wuhan Open after a straight-set defeat by Ukrainian qualifier Lesia Tsurenko.
The British number one was beaten 6-2 7-5 in the first round by the world number 96.
Boulter fell 3-0 down in a topsy-turvy first set that produced six breaks of serve, including five in a row, with Tsurenko taking it in 43 minutes.
The second set was more competitive, with Tsurenko making the decisive break in the 11th game before holding serve to seal victory.
The Ukrainian will next play Poland's Magda Linette, who beat 11th seed Liudmila Samsonova 6-2 6-2.
