Mumbai, May 24 -- Some of India's best performers from the T20 World Cup flopped in this IPL season. Three of the leading stars belonged to Mumbai Indians, which brought the side down and resulted in their failed campaign. Skipper Hardik Pandya and pace ace Jasprit Bumrah were hampered by injuries and niggles. India T20 skipper Suryakumar Yadav ran out of runs as well as form. "It's a culmination of a bit of (loss of) confidence," MI head coach Mahela Jayawardene said. "He's a gifted player, the way he plays shots and takes on the bowlers. Sometimes when you do that and it doesn't come off and then the next game, game plan-wise, he's trying to change a few things. But that also did not work for him. After the outstanding T20 World Cup he had, Bumrah's lean season caught everyone by surprise. Never before, since his rookie years in IPL, has the lead pacer found taking wickets as difficult as this year. Bumrah's meagre haul of four wickets in 13 matches have come at a SR of 73.5. Even his ER (8.37) is on the higher side compared to his standards. Jayawardene revealed it may have had something to do with a minor injury. "Coming back from the World Cup, he had a slight niggle which he played with through the World Cup. The first 4-5 games it was a gradual build-up for him to get over that niggle. You could see the pace dropped because of that. Now, he's back to his pace. The last 4-5 games, he's been good. But when you're going through something like that, you do lose a little bit of sharpness of execution and all that because you're fighting something else."...
