Mohammad Ahsan and Hendra Setiawan paired up to cause South Korean heartbreak in the badminton as they defeated local heroes Yoo Yeon-seong and Lee Yong-dae in the men's doubles final.

In one of the most highly anticipated finals of the day, the 2013 world champions, and half of the duo that won gold at the Beijing 2008 Olympic Games, sealed a 21-16, 16-21, 21-17 victory against the 2014 world silver medallists, to cause agony among the home fans.

The Indonesians were looking strong in the opening set and, after taking an early lead, never looked like dropping back into the South Koreans' firm grip.

With partisan fans behind them, despite a very local Indonesian gathering, Yoo and Lee, part of the men's gold medal winning team, struck back in the second, reversing the scoreline of the opening game to move level for the match.

As the tensions began to build and the crowds grew louder, it looked as though the South Koreans would snatch the win as they led throughout the majority of the third game.

Things turned at 16-16, however, as Ahsan and Setiawan moved up to another gear, pulling ahead of their opponents and staying there as they recorded a 21-17 final game to seal gold.

The match followed an all-Chinese affair in the women's singles that saw Wang Yihan topple team mate Li Xuerui in a reverse of the result from the London 2012 Olympic final.

The pair had played together in the earlier team final, however, there was no love spared in this final as Wang exacted sweet vengeance on her compatriot with a 11-21, 21-17, 21-7 scoreline.

On the athletics track, Qatar's Nigerian-born Femi Ogunode blew the field away in the men's 100m final as he set an Asian and Asian Games record of 9.93sec.

Ogunode moved to Qatar in October 2009 and began competing for the nation the following year.

At his first Asian Games in Guangzhou he won the 200m and 400m titles in personal bests of 20.43 and 45.12, respectively, and became just the second athlete in Games history to have won both events at the same competition - Milkha Singh of India first achieved this at the 1958 Asian Games.

His Asian record here beats that of fellow Nigerian-born Qatari Samuel Francis, who finished down in eighth in today's final.

China's Su Bingtian took silver in 10.10 and Kei Takase of Japan claimed the bronze in 10.15.

History was made inside the Dowon Gymnasium as Japan's Yoshida became the first athlete to win gold at four consecutive Asian Games.

The 55 kilogra class competitor has now won Asian Games titles in 2002, 2006, 2010 and 2014, a feat achieved by nobody ever before.

She won Olympic golds at Athens 2004, Beijing 2008 and London 2012 and has won 12 World Championships titles, in every single year since 2003, except for 2004, when no event was held.

Since her debut in 2002, she has won practically every world and international level tournament she has entered.

In September 2006, she surpassed a 100-match winning streak.

In fact, until January 20, 2008, Yoshida had never lost an international match at the senior level and held a streak of 119 consecutive victories, before American Marcie Van Dusen defeated her 2-0 during the Team World Cup series in Beijing, China.

The ninth day of action here also saw China breach the 100 gold medal mark after an overnight tally of 96.

Wang Zhen got the ball rolling as he won gold number 97 with victory the men's 20 kilometres walk in 1:19:45.

China's men swept past their Malaysian opponents 6-0 in the men's team archery contest for number 98, before Lu Xiuzhi recorded a time of 1 hour 31min 06sec in the women's 20km walk for number 99.

Ma Yuanyuan and Xia Xinyi were the duo to tie up gold number 100 as they beat Thailand's Tanaratta Udomchavee and Varapatsorn Radarong 2-0 in the women's beach volleyball final.
