BC1 David Smith, BC3 Patrick Wilson and BC4 Stephen McGuire all made it through the pool stage to the quarter finals as the other five GB athletes were knocked out.
Smith had good wins in his first two matches but lost the last to end up with the toughest possible quarter final against Pattaya Tadtong of Thailand. Facing the World Number 1 will be a rematch of the final in London 2012 with Smith hoping to avenge his defeat in that match. It will take place at 14.00 UK time on Thursday.
Wilson had to recover from a 3-0 deficit in his second pool game but clawed it back and will face Han Soo Kim of Korea, a player he beat 9-2 in Montreal earlier in the year, for a place in the semi finals. He will be on court at 14.00 UK time.
McGuire also came from behind in two of his pool games and still topped his group despite a loss to Dirceu Pinto of Brazil in his last match. World number 1 Yuk Wing Leung of Hong Kong finished second in his group so will be McGuire's opponent at 15.30 UK time on Thursday.
Nigel Murray, Josh Rowe, Jamie McCowan, Scott McCowan and Kieran Steer all exited the competition at the pool stage but will be court side to cheer on their compatriots in their matches.
