The number 1 team beat from number 10 teams. It's the miracle of Cricket. Everyone enjoys cricket.
Not really, Any team can beat any team on their days because almost every team got equal talents in IPL and only they fell short due to wrong combination or not analysing the wickets properly,etc. If you want to call something a miracle the NZ came to India and whitewashed them while India bully any opponent while playing in domestic bilateral series. 
This also shows how a team leading the table might not be the one that wins the trophy. Even though we already have the top 4 teams playing the play offs. The only advantage the top team would have is they had to play just one more match, which decreases their probability of losing.
On another match between SRH and KK, both of which are already eliminated. SRH made a huge score of 278 which is the 2nd highest total for this IPL, the first one being 286 which was also made by SRH and they also have the record for 4 highest team total in IPL. The two being these two and rest two from last year. Yet, last year's 287 still remains the largest team total record in IPL.
