Pune Warriors had only four wins in their entire campaign in 2011, and were expected to struggle again in the absence of their marquee player Yuvraj Singh.
Instead, they've got three victories in four games and are top of the table after upsetting the fancied Chennai Super Kings in front of a boisterous home crowd.
Chennai Super Kings scored 155 runs for the loss of 5 while Pune Warriors scored 156 runs for the loss of 3 with Jessie Ryder 73, and Smith 44 winning by 7 wickets.
It was an all-round performance from Warriors, with their bowlers first stifling the power-packed Super Kings batting by hitting the block-hole as often as possible, backed up by some sharp fielding, something which is a rarity in the IPL.
Jesse Ryder began in a hurry, but calmed down to play through the innings for the first time in his T20 career.
Just when things started to become tense in the chase, Steven Smith hammered a bunch of boundaries, including two in the final over to complete the victory.
