Mumbai Indians have suffered their seventh consecutive defeat in the Indian Premier League (IPL) - this time losing to Chennai Super Kings (CSK) by three wickets.
Chasing a target of 156, Chennai won the game off the last ball of the game.
Former skipper MS Dhoni (28 not out off 13 balls) smashed a six and two fours off the last over to help his side get the required 17 runs.
Ambati Rayudu (40) was CSK's top scorer while Daniel Sams (4-30) was the pick of the Mumbai bowlers.
Earlier, CSK pacer Mukesh Choudhary (3-19) wreaked havoc with the new ball before Tilak Varma's unbeaten 51 off 43 and Jaydev Unadkat's quick-fire 19 off 9 balls lifted Mumbai to 155 for seven.
The latest result extended Mumbai's winless streak this season to seven from as many games.
