The 6ft 2inches tall Taskin Ahmed made his debut for the senior Bangladesh team in 2014. He slowly made progress into the senior side with his consistent performance. He first played for Under-15, then for Under-17,Under-19 and eventually made it to the national side. Taskin took 11 wickets in the 2012 Under-19 World Cup. In his maiden BPL edition, he played for Chittagong Kings and took 4 dismissals for 31 runs in the semi-final of the tournament and came to limelight. In 2014, an injured Mashrafe Murtaza made a slot of fast bowler in the team empty so Taskin Ahmed was named as his replacement in the squad. Ahmed made his T20I debut in 2014.
On his ODI debut, he took 5 wickets against India. He was included in Bangladesh’s squad for the 2015 ODI World Cup and was very impressive throughout the tournament. He was suspended in 2016 for an illegal bowling action but eventually rectified his bowling action. Bangladesh was in dire need of a proper pace bowler after the retirement of Mashrafe Murtaza but the inclusion of Taskin Ahmed proved to be a sign of relief for Bangladesh as he can bowl above 140kph.
