Christina Black downs Jennifer Jones in 1st major upset at PointsBet Invitational

The PointsBet Invitational saw its first major upset in women's competition Friday with Christina Black defeating Jennifer Jones 9-6 in second-round action at the single-elimination curling tournament.

Jones, the women's third seed, led 6-5 after six ends. But after a blank seventh end, Black's sixth-seeded team took the lead with two in the eighth.

The third seeds kept the hammer heading into the final end after a blank ninth. But Jones, who curled a game-low 69 per cent, missed on her last shot to give Black a steal of two.

Black moves on to play Rachel Homan in the semifinals. The second-seeded Homan advanced with a 10-6 win over No. 7 Isabelle Ladoceur.

Top seed and three-time defending Canadian champion Kerri Einarson advanced to the semifinals with a 10-6 win over No. 8 Kayla Skrlik.

Einarson will next face fourth seed Kaitlyn Lawes, who was an 8-3 winner over No. 5 Clancy Grandy on Friday.
