The Dutchman has struggled with dartitis at the Wolverhampton tournament already over the last few days but victory put him through to the knockout stages.
Dartitis is a condition in which a player struggles in the release of the dart.
With the scores at 4-4 in the decisive leg, Van Peer’s condition hit an all-time high.
After Menzies failed to check out on 116, Van Peer stepped up to the oche but struggled to release his first dart.
He hit 100 to reduce his checkout to 79 before Menzies failed once again to check out on just 20 that left him holding his head in his hands.
On his return from the board Menzies accidentally bumped into Van Peer that raised a few boos from the crowd.
Needing double tops to checkout and win the match Van Peer took his time before eventually missing.
His luck looked out with Menzies having three match points but he too failed to hit double 10 and Van Peer was handed a lifeline.
With Menzies looking on, Van Peer finally landed the winning shot that left both players in tears as they embraced.
And Van Peer’s performance went down a treat online.
One user tweeted: “Hi #berryvanpeer you played very well. I was with you during the whole match and have had tears in my eyes. Congrat and all the best for you.
Another added: “That was emotional to watch so god knows what it must’ve been like for the players up there. Well done Berry van peer, a victory of courage! #grandslamofdarts.”
