A day after winning the Team BC1/BC2 gold medal for Thailand, Watcharaphon Vongsa produced a superb comeback in his last-32 match against Japan’s Hidetaka Sugimura.
He trailed 5-0 after the first two ends and was still four shots behind going into the fourth and final end, but was able to level at 5-5 and then won the tie-break to progress.
Vongsa said: ‘The first two ends was not what I liked, or expected, or how I wanted to play. I was a little bit agitated. I will take everything and try to improve from how I did today.’
Adam Dukovich also needed a tie-break to see off Great Britain’s Zoe Robinson, who was mostly a substitute for the bronze medal-winning BC1/BC2 team, after their match also ended 5-5.
Elsewhere in the first of the seeding rounds in the BC2 event, Portugal enjoyed a fine day with three players progressing into the last 16 as Cristina Goncalves (4-1), Fernando Ferreira (5-4) and Abilio Valente (6-1) all recorded victories.
Their fellow countryman Joao Fernandes is the defending Paralympic Games champion in the Mixed Individual - BC1and the Portuguese made a fine start to his campaign with a 6-1 win over Leung Mei Yee of Hong Kong.
Also progressing to the quarter-finals of the same classification were two players from Thailand - Pattaya Tadtong and Witsanu Huadpradit - while Jose Carlos Chagas de Oliveira of Brazil saw off Ji Kwang-Min of the Republic of Korea in a tie-break after their match ended 3-3.
In the Individual - BC3 qualifiers, Ireland’s Johnny Cronin was cheered on by a strong Irish contingent at ExCeL as he saw off world number four Nurul Binte Mohammad Taha of Singapore 6-4 in the morning’s seeding matches, but he must now repeat the feat if he is to progress in the tournament after being drawn against the same opponent in the last 16.
Taha bounced back in the round of 32 to book his place.
The Great Britain duo of 17-year-old Jacob Thomas and 21-year-old Scott McCowan both went through into the last 16 after 8-1 and 11-0 wins respectively over Spanish opponents.
The task does not get any easier for McCowan as he will now take on Jeong Ho-Won of the Republic of Korea, who received a bye into the last 16 as the world number one.
‘It's going to be a tough game. He's the world number one for a reason. But if I play like that in the next game then I'll give him a game and I've got a real chance of going through,’said McCowan.
Choi Ye-Jin of the Republic of Korea and Canada’s Paul Gauthier also impressed with sizeable victories in their BC3 last-32 matches, winning 10-0 and 7-1 respectively.
In the Individual - BC4 there was only one encounter that took place, with 2010 Asian Paralympic Games champion Zheng Yuansen of China recording a comfortable 9-0 win over world number three Jose Dueso Villar - although the Spaniard lives to fight another day as it was only a seeding match for Thursday’s last 16.
