The 31st Summer Olympic Games, Rio

Team Korea failed to add to its medal tally in the Rio de Janeiro Olympics on Monday, with several gold medal favorites suffering shock defeats.

World number-one judoka An Chang-rim was knocked out in the Round of 16 of the men’s 73-kilogram event, where he succumbed to Belgium’s Dirk van Tichelt. 

In the women’s judo competition, second-seeded Kim Jan-di also suffered an early exit after losing to Brazil’s Rafaela Silva in the Round of 16 in the 57-kilogram event.

Archers brought home a mixed result, with top ranked male archer Kim Woo-jin losing to Indonesia’s Riau Ega Agatha by a set score of 6-2 in the Round of 32 of men’s individual event.

Kim won gold in the men's team event last Saturday and also set a 72-arrow world record with 700 points in Friday's ranking round.

In the women's individual event, Ki Bo-bae advanced to the last 16 after a 6-2 victory over Ukraine’s Veronika Marchenko.

London Olympic gold medalist fencer Kim Ji-yeon dashed hope to defend her title early, as she was upset by Italy’s Loreta Gulotta 15-13 at the Round of 16 of the women’s individual sabre.

In table tennis, South Korea’s Jung Young-sik raised hope for a medal when he was leading world No. 1 Ma Long of China by 2-0 at the Round of 16 of men’s individual event, but the Ma came from behind to beat Jung 4-2.

Jung’s female colleague Jeon Ji-hee also lost to Singapore’s Yu Mengyu 4-1 at the Round of 16 of the women’s individual event. With her loss, South Korea also lost a chance to set up an inter-Korean quarterfinal in women’s table tennis, with North Korea’s Kim Song-I progressing to the quarterfinals.

South Korea’s female swimmer Kim Seo-yeong advanced to the semifinals in women’s individual medley after tying her South Korean record.

She clocked two minutes 11-point-75 seconds in Monday’s preliminary, finishing 10th out of 39 athletes. She posted the same record during the National Sports Festival in 2014.

Meanwhile, the South Korean men’s Olympic football team arrived in Brasilia on Monday, to prepare for their final Group C match against Mexico on Wednesday.

Leading runner-up Mexico by goal difference, South Korea can advance to the quarterfinals with a draw with Mexico, but coach Shin Tae-yong said he will not settle for a draw, adding he is convinced his players can produce a win.

With no medals added, South Korea fell by three notches overnight to the seventh in the medal standings by the end of Monday.
