British number two Aljaz Bedene is out of the China Open after being beaten by Czech Lukas Rosol in the first round.
Bedene cruised through the first set and had break points in the second, but Rosol went on to win 1-6 7-6 (8-6) 6-3.
The result prevents Slovenia-born Bedene from breaking into the top 50, having risen to a career-high 54.
Meanwhile, Tomas Berdych captured his 11th career ATP title by beating Spain's Guillermo Garcia-Lopez in the rain-delayed Shenzhen Open final.
Held over until Monday because of heavy rain that drenched parts of southern China over the weekend, Berdych maintained his composure to win in straight sets 6-3 7-6 (9-7).
