Jaipur: Priyansh Arya displayed remarkable maturity for a rookie while Josh Inglis produced a momentum-changing knock as Punjab Kings downed Mumbai Indians by seven wickets here on Monday to seal a spot in Qualifier 1 of the Indian Premier League. Chasing 185, Punjab Kings could not accelerate in the powerplay but Inglis (73 off 42 balls) and Arya (62 off 35) more than made up for a sluggish start with a match-winning 109-run partnership off 59 balls to get their team home in 18.3 overs.
