Masahito Obayashi claimed his first speed skating World Cup win, in the men's mass start, on Saturday, stunning his more fancied rivals after only just qualifying for the final.

The 27-year-old earned 66 sprint points as he crossed in 7 minutes, 56.91 seconds to edge Russia's Ruslan Zakharov on Day 2 of the World Cup opening round in Poland.

Working his way into the lead around the halfway mark, Obayashi held on through the 16th and final lap. Zakharov finished in 7:56.99, with Poland's Zbigniew Brodka rounding out the podium in 8:09.48.
