KRASNAYA POLYANA, Russia (AP) Gold medal contender Mark McMorris is through to the men's snowboard slopestyle finals.

The Canadian rider finished third in the semifinals on Saturday morning, posting a score of 89.25 on his second run to advance.

Billy Morgan of Britain led all riders with a 90.75, followed by American Sage Kotsenburg, McMorris and Yuki Kadono of Japan.

The quartet will join the eight riders who automatically qualified on Thursday. The finals are Saturday afternoon.

McMorris, who is dealing with a broken rib, botched his final landing during his first run and needed to come through the second time down the mountain. He delivered with a solid set and let his shoulders sag in relief when his score was posted.

Kotsenburg is the only American in the finals.
