Already assured of a semi-final spot, PV Sindhu dispatched Japan's Akane Yamaguchi in straight games but Kidambi Srikanth's dismal run ended with another defeat at the $1 million Dubai Super Series Final here on Friday.
World No 3 Sindhu, an Olympic silver medallist, thrashed World No 2 Yamaguchi 21-9, 21-13 in just 36 minutes to top group A in women's singles at the Sheikh Hamdan Indoor Stadium here.
However, world No 4 Srikanth suffered his third straight loss in men's singles Group B, going down 17-21, 21-19, 14-21 to All England Championship finalist Chinese Shi Yuqi in the last group stage match.
Sindhu, who clinched two Super Series titles this season before winning a silver at the World Championship, will tomorrow face China's Chen Yufei, who saw off Thailand's Ratchanok Intanon 21-18, 13-21, 21-18 in another Group B match.
The 22-year-old Indian showed great anticipation and athleticism to completely dominate the proceedings even as Yamaguchi got buried under a heap of unforced errors in the last Group A women's singles match.
Before the match, Sindhu had a 4-2 head-to-head record against Yamaguchi, which included a win at the Hong Kong Super Series last month.
Sindhu made a rousing start to the match, zooming to a 5 -0 lead.
Sindhu entered the opening break at 11-1 with a superb return and continued to rule the roost after the breather, reaching 15-4.
At 18-6, Sindhu committed a fault at the net but she followed that with a smash and gained 13 game points when her opponent went wide again and Sindhu wrapped up the opening game with a delightful cross court drop.
The second game started on an equal footing with Sindhu and Yamaguchi splitting the initial four points after engaging in some fierce rallies. The ordeal continued for Yamaguchi as she struggled to control the shuttle, allowing Sindhu to move to a 13-8 lead.
A low lift at the forecourt and an overhead return going to net further swelled Sindhu's lead. The Indian capitalised by a cross court drop, reaching 18-12.
A deceptive return and another miscued stroke by Yamaguchi handed Sindhu seven match points and she sealed it with a quick reflex near the net.
After two straight losses, Srikanth stretched Shi Yuqi to the decider after grabbing the second game but he was no match to his opponent in the third
game.
