Mumbai will hope that Sarfaraz, who smashed a scintillating double century (227 off 219 balls) against a Hyderabad attack which included India pacer Mohammed Siraj in his last Ranji appearance, continues his blazing form.“I didn’t play well in the first 3-4 matches, but it was my fifth double century, so I was excited. I didn’t make a century, but I made 40-50. You guys say that I make big runs, so what can I do? Even 40-70 are good,” Sarfaraz added. “I don’t think about the future. All I have in my mind is what I have been doing for so many years. I will keep practising, trying to improve. I am working hard in white-ball cricket. I want to play for India in (the) white-ball (format). I’m focusing on that. I am also working with (younger brother) Musheer (Khan) on his bowling and batting.”Sarfaraz also recalled that recuperating for “45-50 days” at the BCCI’s Centre of Excellence in Bengaluru after suffering a quadriceps injury in August last year was “very tough” for him.“The NCA is very tough. You are alone there. The travelling is also long. You travel for 40-45 minutes from the city to the airport. It is very tough. You get frustrated by the injury. You keep thinking, what about me? These things keep happening,” he added.
