The Australian fast-bowler was a part of the RCB squad during 2015 but failed to leave any mark. In the two matches that he played, he went wicketless. However, he has become a different bowler now. The 24-year-old was in brilliant form in this year’s Big Bash League, finishing the tournament as its highest wicket-taker with 20 scalps from 10 outings, including a five-wicket haul. He has the ability to bowl well with the new ball as well as the old one and RCB can seriously consider him as a replacement for his fancied compatriot.
