Daredevils' seamers limited Super Kings to 169 and than their batters up the order hunted down the target in 19 overs.
The Delhi openers forged a brisk 115 run stand in less than 12 overs. Sehwag took the attack to the opposition from the word go cutting Ntini for a max over third-man in the very first over. In the following over bowled by inexperienced seamer Manpreet Goni Viru garnered as many as 16 runs including two sixes.
From then on there was no looking back for the Delhi and India swashbuckler who struck seven boundaries and four sixes in his hurricane knock. He massacred the Chennai attack studded with the likes of Ntini and Muralithran.
On the other end Gambhir took some time getting into his groove. The attacking southpaw showed a special liking for Joginder belting the medium pacer for two fours and a six in a over. Gambhir hit five fours and a six in his 37-ball knock before playing Goni on to stumps.
AB (26* off 21) and Dhawan (19* off 17) ensured Delhi home with no futher damage.
Earlier Daredevils' pace attack mentored by TA Sekhar of MRF pace academy and spearheaded by McGrath restricted the local outfit to 169 despite the fine effort from Vidyut and Dhoni up the order.
McGrath, Asif and Yomahesh chipped in with a wicket apiece as Delhi unit kept a tight clamp on local outfit. The young India U-19 left-arm seamer Pradeep Sangwan playing his first match for Delhi though went wicketless but conceded too little.
The local lad Vidyut Sivaramakrishnan top-scored for Super Kings with 37-ball 54 studded with seven hits to fence and one over it off Sehwag. Dhoni and Morkel chipped in with brisk 32 and 28 respectively.
Chennai opting to bat first got off to a fine start despite losing Stephen Fleming. Parthiv and Vidyut shared a quickfire 42 runs in less than five overs. Parthiv yet again failed to build on the start he had cutting Sehwag straight to Yomahesh at point.
Vidyut joined by the skipper Dhoni in the middle and the duo helped their side past 100 in 12th over. Vidyut had his slice of luck with Dhawan spilling a tough chance at fine-leg off Sangwan and most of his shots landing just short of fielders.
The Tamil Nadu Ranji player played an unconvincing innings but nonetheless a effective one for his side. On the other end Dhoni was his usual self. The skipper's 27-ball knock was inclusive of two boundaries and a six over long-leg off Sehwag.
The pair knitted 57 runs in just six overs.
However Delhi seamers battled back strongly in the final five overs plucking wickets at regular intervels besides putting brakes on scoring rate despite the little cameo from Albie Morkel (28 off 16, 3X4s&2X6s).
The local side with a mediocre total and bowling attack will have their task cut out against Delhi's formidable top-order.
