A goal in each half from Manchester City striker Edin Dzeko ensured Bosnia warmed up for their first World Cup with a 2-1 friendly victory over the Ivory Coast in St Louis.
Bosnia came into the game off the back off defeats against Argentina and Egypt but Dzeko opened the scoring in the 17th minute with a neat finish after some chaotic defending from Ivory Coast.
The 28-year-old doubled Bosnia's advantage after 53 minutes with a crisp half-volley which flew past goalkeeper Sylvain Gbohouo.
Former Chelsea striker Didier Drogba netted a stoppage-time consolation goal for the Ivory Coast direct from a free-kick, taking his tally to six goals in eight international matches.
Elsewhere Egypt squandered a two-goal lead after slipping to a 3-2 defeat to Chile in Santiago.
Mohamed Salah and Khaled Kamar scored in the opening 16 minutes to put Egypt firmly in charge, before Barcelona's Alexis Sanchez set up Marcelo Diaz to pull a goal back for the home side after 26 minutes.
Sanchez turned provider again on the hour mark after picking out Eduardo Vargas who hit a first-time finish past Egypt goalkeeper Sherif Ekramy.
And the pacy winger made it a hat-trick of assists with a slide-rule pass to Vargas in the 78th minute which the striker coolly finished.
