United States' teenager Nathan Chen held on to deny Japan a home victory in the men's event at the International Skating Union's Grand Prix of Figure Skating Final today in Nagoya.

The 18-year-old Four Continents champion broke a run of five straight Grand Prix Final titles for Japan at the Nippon Gaishi Hall

He scored a winning total of 286.51 points after the free skate to narrowly defeat Shoma Uno.

Home hope Uno had to settle with a second-best haul of 286.01 after both stars produced error-strewn free skates.

Chen, however, had the advantage of a two-point lead after yesterday's short programme,

Russia’s Mikhail Kolyada was third with 282.00.

World champion Yuzuru Hanyu of Japan had won the last four Grand Prix final before missing out due to injury this time around.
