Hosts Poland will meet Germany in the semi-finals of the FIVB Volleyball Men's World Championship after defeating Russia on Thursday.
The home nation came into the clash in Lodz knowing a win - or a losing bonus point - would seal their spot in the last four of the tournament.
Upon taking the opening two sets, Poland knew they had done enough to at least seal the point they required and although Russia fought back to level, Poland clinched a 25-22 25-22 21-25 22-25 15-11 victory.
The win means they finish Pool H with four points, and progress as group winners, ahead of Brazil, having been victorious in both of their games.
"Our dream was to go to Katowice [for the semi], now we dream about playing in the final," Poland's Michal Winiarski said.
Saturday's other semi-final sees France take on defending champions Brazil, after the former defeated Iran 25-20 25-23 22-25 19-25 15-9 in another match to go the distance.
Success meant France topped Pool G, two points clear of Germany, and in Brazil they face the only side to have also reached the last four in the previous tournament.
Thursday's results mean Iran will take on Russia in the fifth-place play-off in Lodz on Saturday.
