Jakati, a 28-year-old Indian left-arm spinner, varied his deliveries with devastating effect and allowed just 24 runs as Delhi were restricted to 145-8 in reply to Chennai's 163 all out.
He struck with the key wickets of David Warner, Dinesh Karthik, Tillakaratne Dilshan and Pradeep Sangwan.
Earlier, Subramaniam Badrinath top-scored with 45, Suresh Raina added 32 and Matthew Hayden had 30 to give Chennai a competitive score at the Wanderers in Port Elizabeth.
Chennai then fielded exceptionally, with Raina making a one-handed catch in mid-air at point to dismiss Gautam Gambhir on 13.
Tyagi stunned Delhi with another wicket in succession, bowling AB de Villiers for a golden duck with a shorter delivery to leave the score on 20-2.
A fourth-wicket stand of 74 runs between debutante Warner and Karthik revived Delhi and made it look like they were about to overturn the advantage.
But Jakati got the big breakthrough in the 16th over when Warner was stumped by Mahendra Singh Dhoni looking to smash past midwicket.
"He's a very good spinner," said Chennai captain Dhoni.
"He's been bowling well in the nets. He was in the team for the last game but we didn't bowl him.
"It's nice to see a young left-arm spinner coming through."
Royals halt Chargers
Earlier on Saturday Lee Carseldine top-scored with 39 and Abhishek Raut hit an unbeaten 36 to steer the Rajasthan Royals to a three-wicket win over the Deccan Chargers.
"We showed a lot of character today," said Rajasthan captain Shane Warne.
"There is a good spirit in our camp. There is no reason now why we can't go all the way to the semis."
Carseldine, a 33-year-old Australian left hander, hit six boundaries in 32 balls in Rajasthan's 142-7, dominating a crucial third wicket partnership that produced 51 runs with Ravindra Jadeja.
