Krisztian Pars and Anita Wlodarczyk took the 2013 hammer season to new heights with their victories at the 11th Athletic Bridge - Memorial Zdenka Hrbacka in Dubnica nad Vahom.
Hungary's Olympic champion Pars gained quick revenge on Poland's Pawel Fajdek after losing to him at the IAAF World Championships in Moscow as he won by the narrowest of margins with 82.40m.
But the throw was the best in the world this year and Wlodarczyk achieved the same feat as she won with 78.22m.
The events at this European Athletics area permit meeting were part of the IAAF Hammer Challenge and Pars won by just 13 centimetres.
He said: "The conditions were excellent and I am happy I was still able to throw that far after the World Championships where I had problems with my shoulder."
He still managed to throw 80.30m in Moscow but Fajdek triumphed with 81.97m.
This time Pars had the upper hand after starting in style with 80.94m as Fajdek responded with 80.66m.
Pars then reached 81.54m but Fajdek answered like the world champion he is with a personal best and world lead of 82.27m.
But in a brilliant competition, Pars responded this time with 82.40m, another world lead.
Slovenia's Primoz Kozmus did not start after suffering with back problems in the warm up.
But Slovakian Marcel Lomnicky, who was eighth in Moscow, finished third with 77.91m as World bronze medallist Lukas Melich, of the Czech Republic, was fourth with 77.83m.
The night looked good for Wlodarczyk, the 2009 world champion, even in the warm-up as she was throwing 75m and she maintained that form in the competition itself.
She started with 74.79m and then landed her first meeting record with 76.16m and ended with the brilliant 78.22m - the seventh best of all-time.
It gave her victory over American Jeneva McCall, who was second in 74.77m, with Yipsi Moreno, of Cuba, third with 73.30m.
The hammer event took place before the main meeting where, in front of 4000 fans, Jan Kudlicka and Czech Republic teammate Michal Balner both cleared 5.68m in the pole vault to break the meeting record.
Kudlicka won on countback and then failed in his bid to break the national record of 5.82m.
There was another meeting record in the 3000m walk as Slovakia's Anton Kucmin won in 11:00.68 while Bulgarian shot putter Georgi Ivanov produced 20.25m to earn a fine win over Canada's Dylan Armstrong with 20.15m and Christian Cantwell, of the USA, with 19.82m.
The 600m could hardly have been closer as Hungarian Tamas Kazi won in 1:17.10 from Jan Kubista, of the Czech Republic, in 1:17.11 and Slovakia's Jozef Repcik, third in 1:17.31.
