Rahul brought in spin from both ends as soon as the field spread out, and it worked when Krunal Pandya hit Rahane's leg stump to send him back for 36 off 24.
Dube departed at 5, but it was Jadeja who collected boundaries in successive overs, hitting the spin of Krunal and Ravi Bishnoi.
However, Jadeja did not enjoy the company of CSK's big hitters for long. Dube first miscued a Marcus Stoinis's short ball, bowled at 125.4 km/h, to be taken by Rahul, and soon after Sameer Rizvi danced down the pitch to Krunal but couldn't get close to the ball and was stumped. CSK were suddenly 93 for 5 after 13 overs.
The LSG bowlers smothered Moeen Ali and Jadeja, who went 34 balls without a boundary. Jadeja finally broke the drought in the 16th over, reaching 50 in the 17th with a six over Mohsin Khan which Deepak Hooda should have taken but just tipped.
