Anderson hit a nine-darter along the way with him saying he fancied hitting it but that it put him on the back foot afterwards which made him miss darts at double.
He did give credit to his opponent though as well as to his next one Jeffrey de Zwaan who he thinks the winner of the
World Matchplay will have to beat.
"I fancied hitting the
nine-darter tonight," revealed Anderson afterwards.
"Hitting the nine-darter so early was actually the worst thing I did because it gave me time to think about it and I missed a lot more darts at tops than I normally do.
"Joe played well, he's been playing well for the last few games so it's great to get the win over a top player.
"Next up it's Jeffrey, who has been the player of the tournament for me. Whoever wins this tournament will have to beat him."
