Tinkoff-Saxo has added another Slovakian to help World Champion Peter Sagan's efforts next year with the signing of U23 European road champion Erik Baška.
The 21-year-old rode for Czech Continental team AWT-GreenWay the past two seasons and is known for his fast finishes.
Sagan said he was "doubly pleased" to have a fellow Slovakian, whom he called a "strong serious rider," join the team.
"His recent victory at the U23 European championships speaks for itself, and I look forward to welcoming him to the team," Sagan said. "I think Erik is an example of the serious work at a grassroots level carried out in Slovakia and I am proud of him."
In 2015, Baška's wins include a stage at the Tour of Berlin and the Carpathian Couriers U23 race. His biggest result came at the European championships, where he took the win from a bunch sprint.
According to a statement released by the team, Baška started out cycling at the age of 14 and joined the strongest Slovakian team, Dukla Trencin in 2013. In 2015 he moved to AWT Greenway. Baška is a three-time Slovakian U23 individual time trial champion and won three UCI races in 2014.
"This is obviously a unique chance for me and I couldn't be any happier," he said. "I am given the opportunity to join one of the strongest teams in the peloton and support the World Champion, Peter Sagan. This doesn't happen every day and I will do my best to demonstrate I'm worth the faith they showed in me."
Tinkoff-Saxo director Steven de Jongh said Baška's European championship confirmed his talent.
"He is a fast sprinter and I think he could be a good support for Peter Sagan," De Jongh said. "Similar to the other young riders that will join Tinkoff Team next year, he will have the best training and racing program to progress."
