FREESTYLE SKIING: Winter Olympic Games hopefuls Brodie Summers and Nicole Parks scored upset victories in the ABOM Mogul Challenge, the last event of the national ski championships.

Summers and Parks turned the tables on the two pre-event favourites, Matt Graham and Britt Cox.

Graham, who has won the last four ABOM events, was chasing a record equalling fifth victory but had to be content with second place ahead of Rohan Chapman-Davies in third.

Parks added a second ABOM trophy to a previous win in this event in 2009 with a narrow 13-12 win over second placed Madii Himbury.

While in many ways it was a surprise that Cox, with two World Cup podium finishes to her name, did not win her fourth consecutive ABOM, it was an even bigger shock that Cox failed to win through to the final.

Cox lost a tight semi-final dual with Himbury, with Cox relegated to third after winning the consolation final.
