Players are breaking sweat training for IPL 2020.
Mumbai Indians, who are based in Abu Dhabi, shared a video of Jasprit Bumrah bowling in the nets.
Boom Boom can be seen imitating the bowling actions of a number of cricketers.
MI asked fans to guess Boom Boom's different bowling actions.
He began with the action of MI mate Lasith Malinga who has pulled out of the IPL for personal reasons.
Boom Boom then imitated the legendary Glenn McGrath before trying Ashish Nehra's left-arm bowling action.
He, then, turned to spin, imitating Kedar Jadhav, Shane Warne and Anil Kumble respectively.
Boom Boom, who looks bashful and serious on a cricket ground, is a funny kid after all.
