NEW DELHI: Improving India’s bowling remains the team’s focus ahead of the Twenty20 World Cup next month, skipper Rohit Sharma has said, adding that he backs seamer Bhuvneshwar Kumar to come out of a recent slump. India went past Aaron Finch’s Australia by six wickets to clinch the three-match T20 series 2-1, and now host South Africa for a white-ball series starting Wednesday. The team’s batsmen, including Virat Kohli and Suryakumar Yadav, have been in good form and shared a 104-run partnership to secure victory on Sunday, but the final-overs bowling has been a cause of worry. Kumar, once a champion of choking runs in the final overs of a T20 match, has been expensive lately. He leaked 21 runs in the 18th over in the series-decider, with Tim David hitting him for two sixes and a four. “We know that he has had more good days than the bad days in the last so many years,” Rohit said of the veteran fast bowler in a post-match press conference. “Yes, of late it has not been the kind of performance that he wants but that can happen to any of the bowlers. You can see the opposition as well, it’s not easy to bowl in the death.” The 32-year-old Kumar, who remains a key member of the team’s plans for T20’s showpiece event in Australia, had just two wickets from two matches and an expensive economy rate of 13.00. Rohit said the team will devise a better strategy in the three T20 internationals against the Proteas to help Kumar return to his miserly ways in the final overs.
