James Wade completed only the third whitewash in the history of the Premier League, beating Simon Whitlock 8-0 in Cardiff on Thursday, as world champion Adrian Lewis avenged a poor defeat in his opener to take a win in his other match at the Motorpoint Arena.
Wade, the 2009 Premier League champion, produced a clinical display to see off the Australian, who was limited to only three darts at a double in a below-par display.
The win moves Wade up to second in the league table following a unusual night in Cardiff, which saw Lewis compete twice in the absence of Gary Anderson, who was attending his father's funeral in Scotland.
The evening began with an emotional minute's applause in memory of the late two-time World Champion Jocky Wilson, who passed away last Saturday, as the seven players and former stars Rod Harrington and Keith Deller led the tributes on stage.
Adrian Lewis and Andy Hamilton contested the night's opening match, and it was the The Hammer who took an 8-4 victory to avenge his world final defeat to Jackpot.
Lewis was punished a string of missed doubles as he fell 5-1 behind at the break and Hamilton closed out the match to record just his second win on the campaign, his first since the opening night.
"I've been playing well throughout the Premier League but fortunately I hit my doubles tonight," said Hamilton.
"There were some big finishes there which I had to take out and I did that well. It's all about handling that pressure, and I can be a force to be reckoned with if I keep doing this during the second half of the season," he added.
Lewis returned to the stage for the night's final game, and turned the tables on van Barneveld by hitting finishes of 160, 110 and 106 in taking a superb 8-2 win over the Dutchman.
Barney lacked the ruthlessness that had been showcased in recent weeks and appeared unhappy with Lewis's celebrations early in the game.
"I'm pleased to come out of the night with two points," said Lewis. "I was setting my sights on playing Raymond and then when Gary unfortunately lost his father I found out that I'd play twice and that's difficult to prepare for.
"Andy Hamilton took his chances really well in the first game and fair play to him, but I did the same against Raymond."
Phil Taylor recorded his seventh successive victory and continued his unbeaten run this season with a superb 8-2 defeat of Kevin Painter, completing the victory with a ten-dart finish and averaging over 113.
Taylor is now 11/2 with official betting partner William Hill
to remain unbeaten throughout the final six weeks of the league season, and he added: "It's my objective to win every match and to win the final.
"The other players just want to make the top four but I'm looking at the final because I want the trophy back from Gary Anderson."
Wade has now been installed as the 15/2 second favourite to win the event, behind William Hill's 1/2 favourite Taylor, and the left-hander admitted after his whitewash win: "It's a good win for me and it could be important when we get to the Play-Offs, I could see Simon was struggling but I had to get the job done."
The McCoy's Premier League Darts continues at the Capital FM Arena in Nottingham next week, while Anderson is now scheduled to play twice in Sheffield on April 12 to make up his game in hand.
