Parthiv and the right length The toughest thing to figure out for a fast bowler while bowling to Parthiv Patel is the right length. His stature allows him to go on the back foot quickly and, while he doesnt get close to the ball when it is full, he is adept at playing on the up on the front foot. In addition to that, he is comfortable opening the face of the bat to get singles. The ideal length is to make him drive but the lack of lateral movement off the pitch makes it a difficult to go fuller often. The seamers pitch-map to Parthiv suggests that Englands bowlers tried too many things without sticking to any one method for long enough.Rahul and the impact of the IPLKL Rahuls young Test career can be divided in two halves -- before and after the IPL. There has been a visible change in his approach after his successful season with RCB in 2016. Before, his strike rate in Tests was 47 but post-IPL it has shot up to 62 runs per hundred balls. The average number of balls he takes for a boundary stroke has also come down to 12 from 18. He started the second day in Chennai with two lofted shots against Liam Dawson and went on to reverse sweep Moeen Ali. While the world has moved back to more orthodox Test openers (David Warner is the only aberration), Rahul is taking a different path. In Tests, the technical aspect of batting overshadows the mental side of it but Rahul is highlighting the role mindset plays in the course you take. He hasnt made any technical changes to bat more fluently--its just the mindset that has changed in last six months.Rashid fits a season into a tour (almost) The criticism of Englands spinners has been about their accuracy, which imperative for penetration. While Indian pitches are spin-ready, the conditions still demand a spinner pound the same area ball after ball, over after over. Adil Rashid is Englands most successful bowler in this series but his economy rate suggests that he hasnt been able to build enough pressure. Rashid has bowled 274.3 overs on Englands Asian tour, spread over nine weeks - almost as many as the 293.2 he sent down for Yorkshire in the county season (although his involvement was limited by England call-ups). Bowling at the highest level demands takes a lot out of your body and, perhaps in part due to his increased white-ball role, it seems Rashid isnt used to this kind of workload.
