Turkey earned a 25-20, 25-21, 24-26, 15-18 win over the Dominican Republic in the opening game of Pool 11 at the Indoor Stadium Huamark in Bangkok.

Italy, playing in Pool nine at the Hong Kong Coliseum, beat the Netherlands 25-13, 22-25, 25-19, 25-16.

The results left Turkey top and Italy second, each with a record of six wins and one loss since this year's event got underway last month.

Italy's Indre Sorokaite served seven aces against the Netherlands, tying the all-time Volleyball Nations League record of most aces in a single match.

In the other two matches played today in their groups, China took their record to five wins and two losses with a 3-0 victory over Japan in Hong Kong, while Thailand beat Bulgaria 3-1 in the Dominican Republic.

A total of 16 teams are involved in this competition, with finals due to be held from July 3 to 7.

In the two other pools being contested in week three, Poland had the chance to move level with the top two teams in terms of their win loss record.

But they were unable to withstand the power of world champions Serbia, who earned a 27-25, 25-21, 25-22, with Katarina Lazovic contributing 18 points to the winning total.

The Poles had arrived with a five-match winning run, while the Serbians had only managed three wins and three losses.

But they had no answer to the power of the Serbs on the day.

Defending champions United States matched the 6-1 record of the top two after defeating South Korea in their opening match.

They came from one set down to reassert their dominance and win 19-25, 25-15, 25-22, 25-19 at Pinnacle Bank Arena in Lincoln. 

Germany edged past Brazil at the same venue in a five-set thriller, eventually triumphing 21-25, 31-29, 21-25, 25-20, 15-13. 

The competition continues tomorrow.
