Konta played well, but will be concerned about her inability to build upon a promising start.
This was the fourth straight match when she has blown a first-set lead against an opponent ranked inside the world's top 10.
World number one
Simona Halep was given a walkover after Madison Keys withdrew due to a rib problem.

Caroline Wozniacki to retain the top-ranking going into the French Open.

"I felt my rib in my match yesterday and after trying to warm up this morning it was still painful," she said.
Halep, runner-up last year, will play either
Sloane Stephens or Caroline Garcia in the last eight
