Taylor, a 16-time world champion, was making his way to the oche for his match with Dutchman Raymond van Barneveld when he alerted security to the attack.
Taylor won the match 7-3, but spoke afterwards of his disappointment at the spitter’s actions and said that he was “a bit disgusted”.
“I wanted to give the fans a show,” he said. “It’s a shame if one tries to spoil that.”
Two years ago at the same event, fellow English darts player Adrian Lewis was attacked with a glass of beer and struck by a coin during a match. Lewis described the actions of some in the crowd as “sad”.
