Regina's Mark McMorris successfully defended his snowboard slopestyle title at the X Games on Saturday, while fellow Canadian Max Parrot earned silver.

The 19-year-old McMorris won with his third-run score of 98.00 — the highest in the event's history. The victory comes a day after McMorris failed to defend his title in the men's snowboard big air final after being nudged out of the top spot by a perfect score from Norway's Torstein Horgmo.

McMorris edged out Shaun White in the slopestyle after the five-time winner fell on his final two runs and settled for fifth place.

McMorris pulled out a difficult cab double cork 1260 on his last run, which bumped his score from 94.66 to 98.00.

White and McMorris are expected to challenge for the 2014 Olympic gold medal when slopestyle debuts in Russia.

Parrot, and 18-year-old X Games rookie from Quebec, placed second after landing a triple cork to earn a 90.00. Belgium's Seppe Smits claimed bronze.

Meanwhile, Spencer O'Brien of North Vancouver, B.C., won bronze in women's snowboard slopestyle with a score of 88.66.

O'Brien finished behind American Jamie Anderson (93.00) and Sarka Pancochova of the Czech Republic (90.).

Montreal's Turski picks up ski slopestyle silver

Montreal's Kaya Turksi earned a silver medal in ski slopestyle at the X Games on Sunday, while fellow Canadian Dara Howell earned bronze.

Norway's Tiril Sjastad Christiansen — at 17 the discipline's youngest gold medallist — pulled off an upset win against Turski, who was looking for a fourth straight gold medal at the event.

Turski crashed on her first two runs and was sitting in last place going into her final run. The 24-year-old needed to beat Christiansen's 92.33 score for a record fourth title, but only scored 90 with a run that included a rodeo 540, a switch 720, and a switch cork 540.

"I'm so excited about the silver medal a and relieved," said Turski. "You know, the second rail kind of messed with me, it's so silly, I feel like it's often the features you don't even think twice about that give you a hard time and today they did."

Turski was forced to wait at the top of the course for more than 30 minutes before her third run as officials attended to Chicago's Ashley Battersby, who crashed on the course and slid into the retaining fence. Battersby was taken to a hospital with a knee injury.

"It was for sure a little bit of a mind game and the course changes a little over that time too," said Turski.

That was the second serious injury of the day as Rose Battersby (no relation) of New Zealand was taken to hospital following a serious fall in training.

Howell, an 18-year-old X Games Aspen rookie from Huntsville, Ont., held the lead momentarily in the middle of the second round before finishing with the bronze at 89.33.

"I missed my grabs a little bit, but I'm happy to be on the podium," said Howell. "I definitely want to keep progressing. I want to keep pushing the sport and pushing myself and today was a run I knew I could put down and I just have to get those grabs better for next time."

Meanwhile, Alex Bellemare of St. Bonfiface, Que., was fourth on the men's side with a score of 90.66.

American Nick Goepper won the gold with a third-run score of 94.00, followed by Sweden's Henrik Harlaut (92.66) in second and James Woods (92) in third.
