Saina came up with a series of sharp cross court smashes to extend the lead and finally sealed the issue rather comfortably when Mitani hit wide.
After Saina's victory, a lot was expected from Sindhu and the teen sensational delivered once again in style.
In a battle of nerves, both the shuttlers struggled to control the shuttle and committed many unforcederrors. While Sayaka lost more than a dozen points at the nets, Sindhu erred in her judgement of the shuttle and gave away points when she could not reach the shuttle at the forecourt.
However, in the end it was Sindhu who had the last laugh.
In the first game, world No 13 Sayaka opened up a 9-6 lead early on but Sindhu repaired the deficit and went into the interval with a slender 11-10 lead. However, Sayaka clawed back with a mid-court smash at 16-16 and wrested back the lead when Sindhu hit long. In the end, Sindhu hit long and found the net to hand over the game to Sayaka.
