Mukul Choudhary hit seven sixes in the death overs to power Lucknow Super Giants to a three-wicket win over Kolkata Knight Riders in the Indian Premier League on Thursday. The 21-year-old Choudhary, playing his first IPL season, dashed Kolkata hopes for its first win in the tournament with an unbeaten 54 off 27 balls as Lucknow reached 182-7 off the final ball. Unbeaten cameos from Rovman Powell (39) and Cameron Green (32) lifted Kolkata to 181-4 after captain Ajinkya Rahana lost the toss and was put in to bat.
