Question: Which opponent who beat Miskew's team in the first two Grand Slam of 2012-2013 season is the oldest? Passage:The 2012–13 curling season was Miskew's most successful to date on the World Curling Tour. In her first Grand Slam event of the season, the 2012 Curlers Corner Autumn Gold Curling Classic, her team lost to Sherry Middaugh in the final. In the second Grand Slam event of the season, the 2012 Manitoba Lotteries Women's Curling Classic, the Homan rink once again lost in the final, this time to Stefanie Lawton. The team lost in the semi-final of the third Slam, the 2012 Colonial Square Ladies Classic but followed it up with their first ever Grand Slam victory at the 2012 Masters of Curling where she beat Chelsea Carey in the final. Outside of the Grand Slams, Miskew and her team won the 2nd Royal LePage OVCA Women's Fall Classic. Later in the season, they qualified for her second Scotties Tournament of Hearts by going undefeated at the 2013 Ontario Scotties Tournament of Hearts. The Homan rink tore through the competition representing Ontario at the 2013 Scotties Tournament of Hearts in Kingston, Ontario. The team lost just one game, to Manitoba's Jennifer Jones. This gave the rink a 10–1 record, 2nd behind Manitoba who went undefeated. However in their first playoff game against Jones, the Homan rink made amends by defeating Jones 8–5. This put the Homan team in the final, where they faced Jones once again, and this time would beat them again, by a score of 9–6. With the win, the Homan rink becomes the first Ottawa-based team to win the Canadian women's curling championship. The win earned Miskew and her team the right to represent Canada at the 2013 World Women's Curling Championship in Riga, Latvia. At the World championships, the Homan rink led Canada to an 8–3 round robin finish, which put them in third place. In the playoffs, they beat the United States (skipped by Erika Brown) in the 3 vs. 4 game, but they then lost to Scotland (skipped by Eve Muirhead in the semi-final, after Homan missed her last shot of the game, jamming a double takeout. After the loss, Homan would go on to beat the Americans once again, this time in the bronze medal game. The Homan rink wrapped up the season by losing in the quarter final of the 2013 Players' Championship.
