British number one Katie Boulter has been knocked out of the Ningbo Open in straight sets by Beatriz Haddad Maia.
World number 10 Haddad Maia completed a 7-6 (7-2) 7-5 victory to reach the quarter-finals, where she will play Spain's Paula Badosa.
The sixth seed dominated a first set tie-break following an even start and then broke Boulter in the 11th game of set two before holding serve to win the match.
It is a first loss to Brazil's Haddad Maia in four meetings for the 28-year-old Briton, who beat Sara Errani in her opening match after exiting the Wuhan Open in the first round last week.
