For CSK, Windies left-arm spinner Akeal Hossain grabbed 4/17 in his third match this season, while Afghanistan left-arm wrist spinner Noor Ahmed showed perfect chemistry returning with 2/23 as CSK returned to winning ways after losing their last match against Sunrisers Hyderabad.
Tilak Varma (37) and Suryakumar Yadav (35) only managed double-digit scores as MI endured a shocking collapse in front of their home fans at the Wankhede.
Earlier, CSK opener and keeper-batter Samson held the innings together with wickets falling at regular intervals at the other end to stay till the end.

Ashwani then plays a dot as the tailenders are delaying the inevitable.
Ashwani then drives the ball to mid-on for a single.
