The 65-year-old from Swinton pipped Failsworth’s Lee Lawton 21-20 to keep alive his hopes of lifting the sport’s most coveted title.
He is one game away from tomorrow’s finals day, with Burton’s Kevin Kelley-Walley standing in his way today.
Walker, who plays for Swinton club Borough Social, reached the Waterloo semi-finals back in 1982.
He raced into an 18-11 lead before Lawton launched a comeback to lead 20-19, only to play two loose bowls at the last end and let Walker in for a double.
Kelley-Walley ended the dream of 18-year-old Jack Hargreaves from Hyde with a 21-16 win.
Hyde’s Tommy Heyes, 66, led title favourite Graeme Wilson (Audenshaw) 16-14 before bowing out 21-18.
Nicky Brooks kept his run going with a 21-18 win over Billy Harding (Barrow).
But other Greater Manchester hopes Ryan Goodman and Clive Chapman (Heywood), plus Andy Buckley (Chadderton), were all sent packing. Tweet
