Sindhu kep her never intact and her confidence high as she smashed and maneuvered her way to a historic 21-16 scoreline, to wrap up the match in straights games.
This was Sindhu's second Super Series title after the China Open past year where she defeated Sun Yu of China in the final.
Sindhu, the world No 5, weathered a fightback from Sung, the world No 4, before winning 21-14 18-21 21-14 to the cheers of a packed audience at the Siri Fort auditorium. Sindhu prevailed 21-19, 21-16 against the current world champion, which was her fifth win over Marin overall. However, the victory will be a huge marale booster for the Indian and soothe the pain of her Olympic defeat.
With the scores level at 19-19, Sindhu launched into the offensive and grabbed the first set 21-19 with two last points. "I am happy with my performance", Sindhu, who won the TOISA player of the year and badminton player of the year awards, said at the post-match press conference.
"It was a good match, Marin played really well". PV Sindhu at fifth and Carolin Marin at the third in the World.
In the second game, the ace Indian shuttler raced into a big lead, surging 11-7 ahead during the break. Her repertoire of strokes, particularly the cross-court ones, gave her a 15-9 advantage, thanks to a spell of six successive points from nine. The Spaniard managed to save one match point but Sindhu sealed it on the very next point when Marin found the net again. The 21-year-old has opened the new season with a Grand Prix Gold title in India as well.
"It was a close encounter and tied at 19-19, either of us could have won it from there". I knew there will be long rallies and Sung will not give points easily. Marin on her part admitted that unforced errors cost her dearly today.
In the men's singles final, Viktor Axelsen of Denmark clinched the title beating Taiwan's Chou Tien Chen in straight games. But then she hit two returns outside the area and handed Sindhu a match point which she converted as Marin hit the return long.
Japanese pair of Shiho Tanaka and Koharu Yonemoto claimed the women's doubles title, while China's Kai Lu and Yaqiong Huang won the mixed doubles title.
