Czech sixth seed Tomas Berdych has crashed out in the first round of the Olympics to Belgium's Steve Darcis.
In a tight opening set on Centre Court, Darcis snatched a late break to clinch it 6-4.
The world number 91 broke once more in the second with a delightful drop shot before he broke again to give him the chance to serve out the match.
However, Berdych got himself back in the contest with his first break, but Darcis then held serve to win 6-4.
The Belgian will now meet Santiago Giraldo after the Colombian saw off American Ryan Harrison in straight sets.
