Cuban high jumper Luis Zayas is set to defend his title at Banskobystrická latka in Banská Bystrica tomorrow.
Both Zayas and Jamal Wilson of the Bahamas achieved jumps of 2.33 metres at the contest last year.
Reigning Pan American Games champion Zayas added three centimetres to his lifetime best and was deemed the outright winner on countback.
He is set to defend his title at Stiavnicky Sport Hall in the Slovakian city tomorrow and will once again be challenged by Wilson.
Joining the field is Wilson's compatriot Donald Thomas, who earned a high jump world title in 2007, a Commonwealth Games gold medal in 2010, and Pan American Games title in 2011.
Other key contenders include Maksim Nedasekau of Belarus and Mateusz Przybylko of Germany.
The men's competition at the Banskobystrická latka is a gold-level meeting on the World Athletics Indoor Tour.
A women's silver-level contest is also scheduled to take place tomorrow.
World silver medallist and Youth Olympic Games champion Yaroslava Mahuchikh is set to face fellow Ukrainian Yuliya Levchenko, 2014 world indoor champion Kamila Lićwinko of Poland, and Italian duo Elena Vallortigara and Alessia Trost.
All five athletes have personal bests of two metres or higher.
