Kolkata Knight Riders edged Lucknow Super Giants via Super Overs in a battle between two bottom-placed teams in the IPL, here on Sunday. Chasing a modest 156, LSG suffered a batting collapse and managed to tie the contest and take it to Super Over with No. 9 Mohammed Shami striking a last-ball six against a wayward Kartik Tyagi, who leaked 16 runs in the final over. But Sunil Narine bowled a stunning Super Over conceding just one run and taking two wickets to give KKR an easy target
