The pair lost to top seeds Marcel Granollers of Spain and Horacio Zeballos of Argentina in the championship match at the indoor hard-court event in Switzerland.
It was Zieliński’s 15th career doubles final, excluding mixed doubles, and his fourth this season, Poland’s PAP news agency reported.
Earlier this year, he fell in the finals in Marseille and Rotterdam with Belgium’s Sander Gille, and in Båstad, Sweden, with Pavlásek.
Zieliński has won five men’s doubles titles, most recently in Acapulco in March last year, partnering with Monaco’s Hugo Nys.
