A four-ender in the eighth has propelled Alliston's Jacqueline Harrison into the playoffs at the provincial woman's curling championship at the Port Arthur Curling Club in Thunder Bay.
She downed Sarnia's Carrie Lindner 8-2 in nine ends.
Harrison, forced into a tiebreaker after losing her final round-robin game earlier on Friday, earned a rematch with Catherine Auld, the author of that loss, in Saturday's 3-4 page playoff.
Thunder Bay's Krista McCarville, who finished 9-0 in round-robin play, will take on Sudbury's Tracy Horgan in the 1-2 page playoff. The winner advances to the final on Sunday, the loser to Saturday night's semifinal.
