TORONTO - Olympic champion Brad Jacobs captured the Players' Championship Grand Slam of Curling event on Sunday with a 4-3 comeback victory over previously undefeated Mike McEwen.

Jacobs, from Sault Ste. Marie, Ont, trailed 3-1 after four ends but grabbed a deuce in the fifth and then scored a single in the eighth to complete the come-from-behind win.

McEwen, from Winnipeg, was the only player to go undefeated leading up to the championship at 5-0 while Jacobs went 4-1 -- his only loss coming against Winnipeg's Reid Carruthers in round-robin play.

Jacobs topped Edmonton's Brendan Bottcher 6-5 earlier in the day to qualify for the finals while McEwen beat Toronto's John Epping 7-3 in the other men's semifinal.

On the women's side, singles in both the seventh and eighth ends gave Scotland's Eve Muirhead a 4-2 win over Russia's Anna Sidorova in the final Grand Slam Curling competition of the season.

Sidorova opened the scoring with a single in the second end before Muirhead tied it in the third.
