About the best bowling figures in T20 International cricket
India seamer Deepak Chahar holds the record for the best bowling figures in T20 Internationals having taken six wickets for seven runs in a T20I against Bangladesh at the VCA Stadium in Nagpur. During this spell, he also became the first Indian male cricketer to take a T20I hat-trick with the wickets of Shafiul Islam, Mustafizur Rahman and Aminul Islam.
Chahar bettered the record of Ajantha Mendis, who took six wickets for eight runs in a T20 International for Sri Lanka against Zimbabwe in 2012 and features on this list twice along with Pakistan seamer Umar Gul.
Among Indians, Yuzvendra Chahal holds the second-best bowling figures in T20 Internationals having taken six for 25 against England at the M Chinnaswamy Stadium in February 2017.
