Kevin Martin squeaked into the quarter-finals of the $100,000 BDO Canadian Open with an 8-3 win over Robert Schlender on Friday.
Knowing he needed a win in the final round-robin draw to advance, Marin opened strong with four points in the first end and finished with three in the sixth to beat fellow Edmonton skip Schlender.
Martin, the reigning Olympic champion, finished the round robin at 3-2, but avoided the tiebreaker with his superior score in the draw-to-the-button shootout held before the event, which is the second leg of the Capital One Grand Slam of Curling.
Edmonton's Kevin Koe and Jean-Michel Menard of Levis, Que., also finished 3-2 and will meet in Saturday's tiebreaker for the final quarter-final berth.
Koe could have qualified for the quarter-final outright but he lost 7-6 to Edmonton's Randy Ferbey in the final draw.
In other Draw 9 action, Winnipeg's Mike McEwen finished the round-robin unbeaten at 5-0 with an 8-3 win over Sweden's Niklas Edin. It was Edin's first loss of the tournament.
Glen Howard of Coldwater, Ont., knocked Winnipeg's Jeff Stoughton from the ranks of the unbeaten, scoring in the sixth end and stealing one in the seventh for an 8-6 win. Both rinks finished at 4-1.
Brad Gushue of St. John's, N.L., beat Scotland's Tom Brewster 5-3. Both teams finished at 2-3.
Saturday's quarter-final matchups are: McEwen versus the tiebreaker winner; Stoughton versus Martin; Brad Jacobs of Sault Ste. Marie, Ont., versus Howard; and Rob Fowler of Brandon, Man., versus Edin.
