Yuvraj's innings comprised eight fours and a six to help Sunrisers reach a respectable total of 162 in 20 overs.
With this win SRH have now progressed to Qualifier 2 round to face Gujarat Lions in the virtual semi-final.
Praising the left-hander's innings, former India opener Aakash Chopra said it was Yuvraj's knock what changed SRH's fortunes around against KKR in the Eliminator match.
"Yuvraj Singh turned the clock back vs Kolkata Knight Riders. His was a match-changing innings," Chopra told NDTV.
Sunrisers registered a comfortable 22-run win against KKR in the IPL 2016 Eliminator, at Feroz Shah Kotla.
Sunrsiers will now take on the losers of the Qualifier 1, Gujarat Lions on Friday (May 27) for their maiden entry into the summit clash of the tournament.
Chasing the target, KKR did not have the best of starts as they lost Robin Uthappa (11) early, caught by Moises Henriques at short extra cover off left-arm pacer Barinder Sran (1/29) in the second over.
