International career
Lin led Taiwan's team to victory in the Junior League World Series in 2010. He played in the 2010 World Junior Baseball Championship, in which Taiwan won the championship. He led all players in the tournament in batting average (.607), on-base percentage (.656), and slugging percentage (.907). For his efforts, Lin was named the tournament's Most Valuable Player, best hitter, and to the All-Tournament Team as a third baseman.

In the 2011 World Youth Baseball Championship, Lin was named best outfielder of the tournament as he played mostly in left field. He also had a catchy nickname, "The Tzunami", because he would destroy opponents like a tsunami does to objects.

Lin played for the Chinese Taipei national baseball team in the 2019 Asian Baseball Championship, appearing at second base, shortstop, and left field, as the team won its first title in 18 years. He was named to the national team roster for the 2023 World Baseball Classic.
