Without many difficulties they were able to defeat Yeon Seong/Eom Hye Won from South Korea 21-12, 21-12 in the final round to win the title.
The 2012 All England champions led the game from the beginning and continued giving pressures to make their opponents unable to fight back.
"We are glad we could win in Singapore despite our loss last week in the Indonesia Open. With the victory our self-confidence is increasing again. We played very well from the beginning," Liliyana said according to a release from the Indonesia Badminton Association (PBSI).
"I did not imagine we could leave them far behind in point collection while the fact is they are a good pair and difficult to beat," Tontowi said.
He said the champion title was meaningful for them with regard to their loss in the Indonesia Open recently.
"From the beginning we could play comfortably," he said.
This was the second title the world`s third ranked players won from the Singapore Open Super Series.
In 2011 Tontowi/Liliyana also won a champion title in the championship. They were absent in 2012 because they had to prepare themselves for the London 2012 Olympic Games.
For Liliyana it was the fifth champion title she won. Pairing with Nova Widianto she won the title in 2004, 2006 and 2008.
