Olympic silver medallist PV Sindhu produced a comfortable straight-game win over 2013 World Champion Ratchanok Intanon at the Hong Kong Super Series to seal a second successive final spot in Kowloon on Saturday.
Last year's finalist, Sindhu moved well and seemed always ready for the shuttle. She dominated the front court, defended well and maintained her attack to outclass the World Number 6 21-17, 21-17 in a 43-minute contest.
It was their sixth meeting and Sindhu was lagging behind 1-4 in the head-to-head count. The only time the Indian had beaten Intanon was at the 2015 Korea Open when the match went to the decider.
Sindhu, a silver medallist at World Championship, will next face top seed and World Number 1 Tai Tzu Ying, hoping to emulate Saina Nehwal and Prakash Padukone, who had clinched this title in 2010 and 1982 respectively.
Locking horns with Intanon after 18 months, Sindhu showed her prowess as she countered the deceptive strokes of her rival with her better defence, which included superb backhand returns and attacking game plan.
In the opening game, Sindhu jumped to a 6-2 lead early on and continued her march ahead, despite some good-looking strokes from the Thai player.
A cross court smash from the Indian left her opponent stranded and allowed Sindhu to grab a 11-7 lead after seven minutes of play. The Thai player struck the shuttle long a few times as Sindhu led 17-9.
Intanon produced a superb cross court dribble to break the rhythm but she again found the net.
The Thai constructed another post with an angled shot to draw Sindhu near the court and then produced a winner on her backhand. But the Indian once again came up with a quick straight return from the front court to move to game point.
The Thai girl produced sensational disguise return to bamboozle Sindhu twice and then the Indian found the net as Intanon grabbed three points.
She again set up Sindhu with her angled return to take another point but the Indian grabbed the opening game when Intanon's backhand return hit the net.
In the second game, Intanon had a 3-1 lead before Sindhu drew parity. An onrushing smash helped Sindhu take a 5-4 lead.
However, two unforced errors again gave the lead back to Intanon. The Thai shuttle then sent a backhand return wide and it was 6-6.
Intanon continued to commit errors, finding it difficult to get the bird away. Sindhu produced another instinctive reactionary stroke to put the shuttle across to move to 10-6 lead with Intanon again going wide.
It was Sindhu who had a healthy advantage at the mid-game breather.
A brilliant forehand defensive return after the break left a stretched Intanon. The Thai player produced a body line smash and returned on Sindhu backhand to grab two points. But the Indian then unleashed a smash to move to 13-9.
Intanon continued to snap at her heels, making it 12-13 with her immaculate placements. A body smash and a controlled deep return from Sindhu helped her to extend the lead to 16-13.
A magnificent on the line smash was followed by two miscued strokes as Sindhu led 18-14. The Indian faltered with a net return and then Intanon produced a straight smash to make it 16-18.
However, the Thai sent the shuttle out again to give another point to Sindhu.
Intanon grabbed another point with a precise return before she went wide to give a match point opportunity to Sindhu, who won it after winning a referral following another wide shot from the Thai shuttler.
