DARTS: Adams edging closer to regaining Lakeside title
"Wolfie" triumphed 4-2 in his second round contest against Lakeside debutante Daryl Gurney, from Northern Ireland, on Wednesday.
The England captain raced into an early 2-0 lead, before Gurney battled back to level the contest.
But Adams, the 2007 champion and the most experienced player at the tournament, took the last two sets to book a last-eight clash with sixth seed Gary Robson.
Adams said: "I would like to have won 4-0, but Daryl threw some very good darts and perhaps it is a case that these close matches wear me down because I am getting older and have lapses in concentration.
"I even tried standing half-an-inch back from the oche but it didn^t help.
"Daryl is a great player and has a big future in the game."
Adams survived a scare against unseeded Englishman Dave Chisnall in his opening match on Monday.
He endured a 63-minute showdown, missing countless doubles before finally winning 3-2.
If Wolfie can see off fellow Englishman Robson, he will face either John Walton or Ted Hankey in the semi-final, with the final taking place on Sunday.
