Smith was managed to follow Wright in the first seven legs, as the Australian only was 4-3 behind at the first break. However, 'Snakebite' proved he was too strong for 'Guru' in the second half of the match.
The local qualifier was able to win one more leg, before Wright claimed a 10-4 victory. The world number two will now meet Rob Cross in the semi-finals. Michael van Gerwen faces Raymond van Barneveld for the second final spot.
