Einar Otto Wallinis a Swedish professional boxer. At regional level, he has held multiple heavyweight championships, including the Swedish title in 2018. He holds a notable win over world heavyweight champion Murat Gassiev.
Wallin comes from a working-class family. His father and one of his brothers boxed, and he began boxing when he was 15. As an amateur, he won the Swedish championship for beginners in 2008. There were few heavyweights available to fight in Sweden, where professional boxing was banned until 2007, so Wallin would often fight whoever and whenever in order to stay active.
In 2009, Wallin won a bronze medal at the Swedish Youth National Championships in the heavyweight division, and won the Ruska Tournament in the super-heavyweight division. In 2010, Wallin won silver at the Swedish National Championships, and silver at the Haringey Box Cup, losing to Anthony Joshua on points in the final. He also won silver at the 2010 Ruska Tournament.
Wallin lost to Joshua on points again in a Sweden–England dual match in Stockholm in January 2011. He then won bronze at the Swedish National Championships in February, silver at the Nordic Championships in March, gold at the Algirdas Socikas Tournament in May, gold at the Haringey Box Cup in June, and gold at the Riga Open Tournament in December.
In January 2012, Wallin defeated Frazer Clarke 32:11 in a Sweden–England dual match in Uppsala, which qualified him for the 2012 European Boxing Olympic Qualification Tournament. Wallin won bronze at the Gee-Bee Tournament in March, losing to Magomed Omarov in the semi-finals. At the European Boxing Olympic Qualification Tournament in April in Trabzon, Turkey, he was eliminated in the round of 16 by Mihai Nistor. Wallin finished with an amateur record of 34–12.
