South African pacer Marizanne Kapp (2/13) struck twice in two balls early on to help Delhi restrict Mumbai, who were put in to bat, to a meagre 109 for 8. Shikha Pandey and Jess Jonassen also chipped in with two wickets for DC.

Chasing a small total, the top three Delhi batters of captain Meg Lanning (32 not out off 22 balls), Shafali Verma (33 off 15 balls) and Alice Capsey (38 not out of 18 balls) competed among themselves in hitting boundaries as their side chased down the target with 66 balls remaining.

Lanning struck four boundaries and one six during her unbeaten knock, while her opening partner Verma hit six fours and one six. One-down Capsey then hoisted five sixes and one four during her blitzkrieg to take Delhi to 110 for one in nine overs. Already in the play-offs before Monday's match, Delhi and Mumbai now have 10 points from seven matches each. But Delhi are ahead on net run rate -- plus 1.978 as against plus 1.725 of Mumbai.

Delhi face UP Warriorz -- who also have qualified for the play-offs -- on Tuesday, while Mumbai take on Royal Challengers Bangalore -- who are out of reckoning -- on the same day. Tuesday's matches will decide which team tops the table and directly qualifies for the final. The second and third place teams will play the eliminator.

Mumbai were in tatters at 10 for 3 in the fourth over and they crawled to their lowest powerplay total of 19 for 3, before another blow struck them. Introduced in the seventh over, Arundhati Reddy struck in her fifth ball, dismissing Amelia Kerr, who offered a loose shot into the hands of Bhatia behind the stumps as Mumbai wickets continued to tumble.
