Having set a near impossible victory target of 490 on a track that is offering help for spinners, Jharkhand are 28 for one with two full days of play left and 462 runs to get.
Earlier, talented Shreyas Iyer's quickfire 81 off 106 balls and captain Abhishek Nayar's 43 off 77 balls enabled Mumbai score 245 in a little over 63 overs in their second innings after Jharkhand were bowled out for 172 in their first essay.
Starting the day at 150 for 8, Shardul Thakur took the remaining two wickets in the morning as Jharkhand were bowled out within 8.5 overs in the day.
In their bid to score quick runs, Jay Bista (14) and Akhil Herwadkar (15) hit a flurry of boundaries before both were out in quick succession.
