Peter Wright claimed his first Premier League win over Michael van Gerwen with a 7-5 victory in Cardiff.
The Scot gained revenge for his defeat in last year’s final to end his eight-match winless streak against the Dutchman in this competition.
Wright missed six match darts in the showpiece at the O2 Arena last May, but produced an impressive performance this time around as he averaged 101.04 and registered a 58.33 checkout percentage.
Rob Cross continued to struggle as world champion, suffering a second consecutive heavy defeat in his debut Premier League campaign, this time a 7-1 hammering by Simon Whitlock.
Like Whitlock, Michael Smith maintained his perfect start to the competition with an impressive 7-4 win over Daryl Gurney.
Gary Anderson, struggling with a back complaint in recent weeks, put any fitness concerns behind him to beat Welshman Gerwyn Price 7-3 in front of his own fans.
Raymond van Barneveld produced a 167 checkout en route to edging past Mensur Suljovic 7-5 in the final match of the evening.
