Louw, who dominated the grueilling four days of qualifying rounds including the Top 24 Round, lost his lead in the final game during today's Top 8 Round-Robin finals and barely made the stepladder finals in fourth position.
The South African had led the round from the start, right up to the final eighth and position round match where he faced Germany's Oliver Morig with a 32 pins cushion. Louw struggled big time and lost to the German, 155-220 but survived to clinch fourth position for the stepladder finals.
Ironically, Louw faced Morig in the semi-finals for a re-match and the South African sailed past the German, 262-196 to advance to the championship round. Indonesia's Ryan Lalisang, who trailed Ireland's Christopher Sloan by 6 pins before the position round match, outclassed the Irishman, 254-182 to snatch the third stepladder spot.
Australia's Sam Cooley finished second to take on the Indonesian in the semi-finals. Cooley also struggled in the match while Lalisang, cheered on by the large crowd of local supporters, breezed past the Aussie, 239-158 to set the finale with Louw.
