Hungary’s Tamara Alekszejev upset the home favourite Laura Asadauskaite to secure a maiden International Modern Pentathlon Union (UIPM) World Cup Final title in Lithuania’s capital Vilnius.
Alekszejev had never finished on a podium at a UIPM competition before, but produced an impressive display in Vingis Park.
The Hungarian triumphed in the fencing round to take an early lead, although her time of 2min 19.56sec was only the 15th quickest in the swimming.
She would begin the combined event clear of the competition having topped the standings in the riding discipline.
Lithuania’s Asadauskaite, the London 2012 Olympic champion, was among those seeking to chase down Alekszejev in the combined event.
Despite her best efforts in front of a home crowd, Asadauskaite was unable to close the gap to the leader.
Alekszejev completed the combined event in 12:37.04 to take gold, ending on a tally of 1,384 points.
"I feel perfect, I can't believe I'm World Cup champion," said Alekszejev.
"I didn't look behind me, I just focused on my shooting.
“After the first two runs I realised that Laura was coming, but I'm strong."
Asadauskaite settled for the silver medal in front of a home crowd, ending with a total of 1,369.
The podium was completed by Russia’s Gulnaz Gubaydullina, who scored 1,365, with Belarus’ Anastasiya Prokopenko just two points behind.
The World Cup Final concludes tomorrow with the mixed team relay.
