Shreyas, whose maiden IPL hundred came off 51 balls, and Prabhsimran Singh (69, 39 balls) added 140 runs for the third wicket as Punjab scaled down LSG’s 196 for two in 18 overs. PBKS made 200 for three.
The victory helped Punjab to reach 15 points from their all 14 league engagements to reclaim the No. 4 position on the table.
But now, they will have to go through an excruciating wait to know their fate as Rajasthan Royals (14) are taking on Mumbai Indians on Sunday at Mumbai.
If RR win the match then, Punjab will enter the playoffs as the fourth placed team with 16 points.
The Kolkata Knight Riders (13 points), who are up against Delhi Capitals in the weekend's second clash, too have an outside chance should RR fail to go past MI.
In that case, it will be a battle of net run rate between KKR and PBKS, with both tied on 15 points. Royal Challengers Bengaluru, Sunrisers Hyderabad and Gujarat Titans are already in the knockouts.
But the equation worries are for another time, as Shreyas showed his steely nerves while chasing yet again with a fabulous knock.
