Since their most recent loss, MI camp can be trusted to have gone back to the drawing board in order to overcome their powerplay woes which has been one of the biggest factors so far. Including a rain-truncated game against Rajasthan Royals which had 3.2 overs of powerplay, Mumbai Indians have taken a mere three wickets in the crucial phase of the first six overs in four matches. Jasprit Bumrah has been spot-on when it comes to containing, but the Indian pace ace has surprisingly gone wicketless in four matches so far. With a seam bowling attack which also has the experienced Trent Boult and Hardik Pandya, the returns have been minimal.
