Punjab Kings rode on skipper Shreyas Iyer's unbeaten ton and opener Prabhsimran Singh's fifty to beat Lucknow Super Giants by seven wickets in an Indian Premier League match here on Saturday. PBKS produced a good bowling display to restrict LSG to 196 for six, a target which they chased down with consummate ease with Iyer (101 not off 51 balls) and Prabhsimran (69 off 39) leading from the front as they stayed in the hunt for a playoffs berth.
