Bosnia and Herzegovina are up to second place in UEFA European Under-21 Championship qualifying Group 1 after Edin Višća scored the only goal against Greece.
The İstanbul BB SK player punished the hosts' failure to clear their lines midway through the second half, running on to a neat pass from Miroslav Stevanović and unleashing a powerful left-footed drive from inside the penalty area that beat goalkeeper Kostas Lambrou.
Lambrou was called into action inside the opening three minutes to save a shot from Nemanja Bilbija, who then had another effort kept out by the Greece goalkeeper. Sandwiching those attempts was a Tassos Lagos header which pressed Semir Bukvić into service at the other end.
Both goalkeepers, from Giannis Fetfatzidis and Višća respectively, were tested again before the end of a lively half, while after the break Višća struck a post. From the rebound the woodwork was rattled again, this time by Bilbija.
Višća then cleared the crossbar but was rewarded for his perseverance after 67 minutes. Greece, beaten 5-4 at home by Germany on Friday, were unable to respond, substitute Nikos Karelis coming closest to an equaliser in added time when he hit Bukvić's left-hand upright.
