The wildcard entrants from Thailand, after earning their first ever semi-finals on the pro tour in Newport last week, managed a crucial break in both sets in the quarter-finals and will play American Scott Lipsky and David Martin for a place in the final.
"We didn't expect to play so well after such a disappointing result at Wimbledon. We practised with Kerr and Thomas earlier this week and lost to them. We were serving really well,'' said Sanchai who together with his brother blast up to eight aces and maintained the high level of first serves at 70 per cent.
The twins step closer to meeting their idols Bob and Mike Byan, the world No 1 twin doubles players who should be waiting for them in the finals if they all clear their semi-final hurdles.
"We absolutely love to play them. But first we have to worry about our rivals in the semis which is not easy."
