Dave Chisnall reached the semi-finals of the Low6 Home Tour Play-Offs, winning Group Four on Friday evening.
A keenly contested Group Four saw the opening three matches all go to deciding legs, as Chisnall lost out to Heta, allowing Dutch youngster Geert Nentjes to storm to the top of the table with back-to-back wins.
World number 11 Chisnall clawed his way back into contention with a convincing 6-2 defeat of Darren Webster to set up a straight shoot-out to win the group in the final game of the night between Chisnall and Nentjes.
Missed doubles from Nentjes proved costly, as Chisnall took full advantage to end the night on top of the group, sealing his place in next Wednesday's first semi-final night.
The Low6 Home Tour Play-Offs continue on Saturday night with Group Five, which will feature World Matchplay champion Rob Cross, 2020 Players Championship event winner Ryan Searle, Home Tour nine-dart hitter Luke Woodhouse and Sweden's Daniel Larsson.
