Nordqvist led after each round of the Honda LPGA Thailand tournament, using a 4-under-par 68 in the final round Sunday to hold off Inbee Park for the win by two strokes.
It was the third LPGA title for Nordqvist but first since she won the McDonald's LPGA Championship and LPGA Tour Championship in her rookie season of 2009.
The title lifts her from 27th to No. 14 in the rankings.
Park, the defending Thailand champion, finished second and Matthew, with a closing round of 65, was third. That finish allows Matthew to go from 13th to No. 10. Paula Creamer, one of three players forced down one spot by Matthew's move up, drops from the Top 10.
Matthew's re-entry to the Top 10 is the only change in the top tier of the rankings. Park has now reached 46 weeks as the No. 1-ranked women's golfer.
The LPGA finishes its current Asian swing with the HSBC Women's Champions tournament in Singapore beginning Thursday.
