Mumbai Indians secured a place in the Indian Premier League play-offs at the expense of opponents Delhi Capitals with a 59-run win.

Chasing 181, Delhi failed to find their feet, slipping to 66-5 at the half-way stage.

Sameer Rizvi offered some resistance with 39, but was bowled by Mitchell Santner, who took 3-11, and Delhi were all out for 121 with 10 balls to spare.

Mumbai struggled in their innings, grinding to 132-5 at the end of the 18th over, having scored just 78 runs in the 12 overs since the powerplay.

However Suryakumar Yadav and Naman Dhir struck 48 from the last 12 balls, closing the Mumbai innings with an unbroken 57-run partnership.

Suryakumar hit a 43-ball 73 that featured seven fours and four sixes, while Dhir scored 24 from eight balls, as Mumbai finished on 181-5.

Delhi's reply started poorly, with captain Faf du Plessis (6) finding Mitchell Santner at long-on in the second over, while the in-form KL Rahul was caught behind for 11 off Trent Boult.

Abishek Porel (6), Vipraj Nigam (20) and Tristan Stubbs (2) also fell cheaply as the first five wickets were shared one apiece by five Mumbai bowlers.

Rizvi put on a 38-run partnership with Ashutosh Sharma (18), but both batters were dismissed by Santner in the 15th over and from there Delhi slid to a big defeat, losing their last five wickets for 18 runs.

The play-off places are now decided, with Mumbai joining Gujarat Titans, Royal Challengers Bengaluru and Punjab Kings in the knockout stages.

Delhi can now finish no higher than fifth, with one game in their season remaining.
