The Englishman picked up a plethora of awards including the man-of-the-match honours.
His 29-ball 62, inclusive of 10 hits to the fence and two over it, helped Royal Bangalore Challengers to a comfortable five-wicket win over Rajasthan Royals [ Images ].
It was his second half century in the tournament - after his unbeaten 66 against Kings XI Punjab [ Images ] earlier in the month.
It was also the second time he had been awarded the man-of-the-match.
Pietersen was also involved in a crucial 60-run third-wicket partnership with Robin Uthappa [ Images ] (26) - a partnership that laid the foundation of the win.
He went ballistic in Kamran Khan's second over blasting 18 runs - including three boundaries on the trot followed by a massive six over midwicket.
And never looked back thereafter, his efforts earning his team a berth in the semi-finals.
