Vinh was left out of the top three after scoring 658.5 points-just 0.1 point less than the bronze medal winner, Wang Zhiwei of China.

Jin Jongoh from the Republic of Korea took the gold with 662 points, followed by countryman Choi Young-rae who scored 661.5.

The Vietnamese marksman was expected to earn a place in the final round before departing for the games.  He exceeded expectations when he became the fourth-highest point shooter after the qualification with a score of 563 points.

At one point, Vinh’s score was only three points less than that of the third-ranked Wang of China, raising hopes for Vietnam’s first Olympic medal.

Vinh also performed well in the eight series, jumping to third place with 78 points

But when his attention faltered for a second, Vinh scored only 7.3 in the ninth series and fell out of the top three. Although he corrected his mistake with 10.2 points in the final series, this was not enough for him to win a medal.

However, it was the highest score that Vinh has attained since the start of his career. It was also an achievement for the country, as Vinh was the first Vietnamese shooter to win a place in the Olympics and his fourth place here is the highest honor Vietnam has achieved in international competitions.

Vinh also took part in the men’s 10m air pistol event last week but did not make it to the final round

After shooting, Vietnam will complete in London in taekwondo, wresting and track-and-field events.

Two taekwondo martial artist, Le Huynh Chau and Chu Hoang Dieu Linh, and female wrestler Nguyen Thi Lua will start their competitions on August 8, while high jumper Nguyen Thi Viet Anh will compete on August 9 and petite athlete Nguyen Thi Thanh Phuc will walk two days later.
