Otto Wallin  Einar Otto Wallin (born 21 November 1990) is a Swedish professional boxer. He held the WBA Continental heavyweight title in 2017 and won the EBU European Union heavyweight title in 2018. 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. Wallin turned professional at the age of 22, in 2013. He trained under Torsten Schmitz for six months in Berlin, Germany, then moved to Copenhagen, Denmark, where he met former two-weight WBA world champion Joey Gamache, who became his trainer. Wallin followed Gamache to New York after Gamache left Denmark. After racking up a 19–0 record and winning the WBA Continental heavyweight title, Wallin defeated Adrian Granat (15–1, 14 KOs) to win the vacant Swedish and EBU European Union heavyweight titles in April 2018. Wallin won by unanimous decision 117–111, 117–112, and 118–110.
