IPL debutant Mayank Yadav turned an unlikely hero with his express pace and three wickets to help Lucknow Super Giants to their first season win on Saturday.

Lucknow beat Punjab Kings by 21 runs at their home ground after they posted 199-8 following Quinton de Kock`s fifty and a quick-fire 42 by stand-in skipper Nicholas Pooran. In reply, Punjab finished on 178-5 despite a 102-run opening stand between skipper Shikhar Dhawan (70) and Jonny Bairstow (42).
