Shamar Kamal Springer began his List A career on January 16, 2015, during the 2014–15 Regional Super50 tournament. Springer’s journey began in Barbados' youth system, representing their Under-17 and Under-19 sides. In 2016, the Barbados Tridents recruited him for the Caribbean Premier League. Despite his rising fame, Springer’s thoughts often returned to his late father, who passed away in June 2016. He dedicated his cricketing success to his father’s memory, underscoring his deep emotional connection to the sport.

By December 2015, his potential earned him a spot in the West Indies squad for the 2016 Under-19 Cricket World Cup, where his performances solidified his reputation. Springer transitioned to first-class cricket on December 14, 2017, debuting for Barbados in the Regional Four-Day Competition. His all-round abilities caught attention again in June 2018, as he was named in the Cricket West Indies B Team for the inaugural Global T20 Canada.

In the 2018–19 Regional Super50 tournament, Springer excelled as Barbados' leading wicket-taker, claiming 16 dismissals in eight matches. His consistent performances earned him another chance to represent Barbados in the 2019–20 Regional Super50. He was further retained in June 2020 during the player draft for the 2020–21 domestic season, reflecting his continued importance to the Barbados cricket setup.

Springer’s celebrations on the field have become as iconic as his performances. Cricket fans fondly remember the Gangnam Style dance from the West Indies’ T20 World Cup victory in 2012. Four years later, Springer’s signature chest-roll dance stole the spotlight when the West Indies Under-19 team clinched the World Cup title.

As a middle-order batter and a handy seam bowler, Springer thrives under pressure. His 62 off 88 balls in a challenging semi-final chase of 227 against Bangladesh in the 2016 U-19 World Cup showcased his adaptability and temperament. Additionally, his blistering 74-ball century against Fiji demonstrated his flair for big hitting. With 285 runs at an impressive average of 57, he ranked among the tournament’s top batters.

After years of consistent performances and growth in various formats, Shamar Springer earned his long-awaited maiden T20 call-up in November 2024, for the West Indies' series against Sri Lanka. He possesses a great deal of promise with both bat and ball, further solidifying his potential as a player to watch out for the future.
