Bosna Sarajevo made it six of the best with a 80-78 win at Hercegovac Bileca to open up a two-game gap at the top of the A1 League play-offs in Bosnia Herzegovina.
Bosna have taken a stranglehold on the play-offs, winning all six of their matches to leave the five other teams with an extremely tough task if they are to overhaul Bosna.
Banjalucka Pivovara and Siroki Hercegtisak are currently the best-placed teams to challenge Bosna, as both have 4-2 records.
Banjalucka defeated Celik Zenica 115-74, but Siroki missed the chance to stay within one game of Bosna as they lost 85-81 at Leotar Trebinje.
That defeat moved Siroki back to third place behind Banjalucka, who have a superior points differential.
