Career
Salin set Finnish records in both the 110 metres hurdles and the 400 metres hurdles and competed in the 1972 Summer Olympics. The same year he broke the Finnish record for the first time, running 14.2 and improving the previous record by one-tenth of a second. Originally the 110 m hurdles were his main event, and he only dabbled in the 400 m hurdles.
In 1970, however, he seriously took up the longer event as well.
He broke the national records in both events several times that year, setting his best times of 13.8 and 49.9 in Prague in a dual meet against Czechoslovakia. Track & Field News ranked Salin fourth in the world in the 400 m hurdles that year.
At the 1971 European Championships in Helsinki he qualified for the final in the 400 m hurdles, placing sixth in 50.57. He remained the last Finn to qualify for a European Championships final in men"s 400 m hurdles until Oskari Mörö did it in 2014.
At the 1972 Summer Olympics in Munich Salin represented Finland in the 400 m hurdles, as well as (with Stig Lönnqvist, Ossi Karttunen and Markku Kukkoaho) in the 4 × 400 m relay.
In the hurdles he was eliminated in the first round, but the Finnish relay team placed sixth in the final and set the still-standing national record of 3:01.12.
