British number three James Ward is out of the Claro Open Colombia after suffering a straight-sets defeat to Jimmy Wang.
Ward was aiming to reach his first ATP Tour quarter-final since Queen's Club three years ago after advancing through the first round when Matt Ebden retired from their match while trailing 6-4 3-0 on Wednesday.
However, the 27-year-old Londoner could not get through the second round as Taiwanese Wang broke him four times on the way to a 6-3 6-1 victory.
Defending champion Ivo Karlovic advanced to the quarter-finals after a hard-fought victory over Dudi Sela.
The second seed was taken to a tie-break twice by his Israeli opponent but eventually prevailed in straight sets 7-6 (10/8) 7-6 (7/5) to set up a clash with Wang.
Eighth seed Victor Estrella Burgos is also through to the last-eight after a 6-4 6-1 win over Peter Polansky.
