Sungjae Im has been breaking records since his amateur days, where he won the 2015 Asian Amateur Championship and represented South Korea at the 2016 Summer Olympics in Rio de Janeiro, Brazil. Since turning professional, he has continued to make history.

In 2018, Im became the youngest-ever player to win the Web.com Tour Championship, earning his PGA Tour card for the 2018-2019 season. He then became the first player born in the 1990s to win the PGA Tour Rookie of the Year award in 2019.

Im continued to impress in 2020, breaking the record for the most birdies made in a season on the PGA Tour, with a total of 494. He also became the first player in PGA Tour history to average less than 69 strokes per round in a season while playing in at least 50 rounds.
