Saina is the first Indian shuttler to win two singles gold medals in badminton in Commonwealth Games as she had previously won at the 2010 event as well.

Saina, who led the head-to-head count 3-1 before today's match, won 21-18 23-21 in the high-pressure match that lasted an hour. However, Sindhu once again gained the three-point lead to make it 18-14 in her favour.

On Sunday, she began with a flourish, went for the big smashes each time the opportunity presented itself and raced to a 11-6 lead. While Saina had some trouble dealing with the brute force of Sindhu's smashes, the latter found it tough to adjust to the delicate placement of her senior's strokes.

Saina had taken the early lead in the second game as well before she fired one wide to allow Sindhu to draw level at 4-4. Sindhu on the other hand, struggled to match her compatriot although she gave a stiff fight in the second game.
