TEHRAN, June 23 (Xinhua) -- Iran became the first team to secure a final six spot, with four matches to spare in pool play, as Amir Ghafour once again led the side to a 3-0 (25-19, 25-19, 25-14) sweep of Australia for their 10th win in 11 games at the 2019 FIVB Men's Volleyball Nations League on Saturday.

The win ensures that Iran remain at the very top of the standings and sets up a most anticipated faceoff with France for Sunday.

Brazil can join Iran in securing a ticket to the final six on July 10-14 in Chicago, if they beat Germany at home in Cuiaba later on Saturday. Team USA, as hosts, are automatically through.

Iran outblocked and outserved the 'Volleyroos' with Ghafour leading the way on 16 points, including three blocks and four aces, before a thrilled 6,000-strong home crowd in Ardabil.

France themselves also extended their winning streak with a 3-0 (25-23, 26-24, 25-23) win over Portugal that places the 2018 Nations League silver medallists in the qualifying zone for this year's final six.

France's Timothee Carle with 12 points and Daryl Bultor with 10 were the only two players with double-digit scoring in the match as the winners overcame Portugal's strong blocking.

Elsewhere, Poland also scored their second win of the weekend holding off Serbia 3-2 (32-30, 21-25, 25-21, 19-25, 15-11) in Milan, to go 7-4 in the standings.

It was the second loss this weekend for Serbia who dropped to 5-6 and are now playing catch-up to be in the race to make the final six.

Poland missed their chance to finish the first set quicker, when Serbia cancelled two set points at 24-23 and 25-24. But the Balkan side then blew their own opportunities to go a set-up, failing to capitalize on five set points of their own, before Poland took the lead again and finished it off with a block by Artur Szalpuk on Drazen Luburic.

Bartosz Kwolek was top scorer of the game on 24 points for Poland, exactly the same as Serbia's Miran Kujundzic.
