Cyprus star Marcos Baghdatis beat crowd favourite and 16th seed Ryan Harrison of the US 6-4 6-1 to advance to the quarter-finals at the Citi Open in Washington.
Baghdatis faces a tough task in his next match, with the tennis star taking on third seed Milos Raonic on Thursday night.
The big-serving Canadian beat Nicolas Mahut of France 7-6 (2), 7-6 (6).
“There are a lot of things I need to be happy with,” Raonic said. “I lost a bit of sharpness and discipline in the second set, but I’m glad I was able to get through and keep going in this tournament.”
