The women's final four is set at the Grey Power Players' Championship curling event in Grande Prairie, Alta.
Calgarians Shannon Kleibrink and Cheryl Bernard, Winnipeg's Jennifer Jones and Kelly Scott of Kelowna, B.C., advanced to the women's semifinals of the season's final Capital One Grand Slam of Curling event with wins in Friday's late draw.
Kleibrink remained undefeated at 4-0 with a 5-3 win over Rachel Homan of Ottawa and Jones cruised past Sherry Middaugh of Coldwater, Ont., 9-2.
In the other two quarter-final games, Bernard won her fourth straight game after squeezing past Heather Rankin of Calgary 4-3 while Scott kept her hopes of securing the fourth and final direct Canadian Trials spot alive after doubling up Krista McCarville of Thunder Bay, Ont., 6-3.
Kleibrink and Scott will meet in one of Saturday's semifinals while Jones and Bernard will meet in the other.
The women's championship game will take place later Saturday (CBC, CBCSports.ca, 3 p.m. ET).
Failure to execute
The top seed in the women's tournament, Kleibrink led 4-3 in the eighth end and managed to escape with the win after Homan failed to execute a difficult two-point double runback on the game's final shot.
"It was such a tough shot for her," said Kleibrink. "If she makes it, she deserves the win."
Jones jumped on Middaugh early, executing an open draw for two in the first and adding a steal of one in the second frame to race out to a quick 3-0 lead.
The reigning Canadian champion put the game out of reach in the fourth end by nailing a short run back for three points and a 6-1 advantage.
"Jill (Officer) and Cathy (Overton-Clapham) played lights out," said Jones. "They just made every roll and took everything away from (Sherry). That makes my job easy."
In men's action, Kevin Martin of Edmonton, Mike McEwen of Winnipeg and Brad Gushue of St. John's, N.L., qualified for Saturday's men's quarter-finals (CBC, CBCSports.ca, 6:30 p.m. ET) after each team won its respective "B" bracket final.
Martin remained in the hunt for his sixth career Players' Championship title with an 8-1 victory over Dale Matchett of Churchill, Ont., while McEwen reached the final eight with an 8-2 win over Wayne Middaugh of Midland, Ont.
Gushue advanced to the playoff round with a 5-4 come-from-behind win over Joel Jordison of Moose Jaw, Sask.
With the victories, five of the men's eight quarter-finalists have been confirmed as Martin, McEwen and Gushue joined defending champion Glenn Howard of Coldwater, Ont., and Randy Ferbey of Edmonton.
Matchett, Middaugh and Jordison can still reach the quarter-finals by winning their respective "C" bracket matches.
