Both these batsmen dominated the innings with quick runs, which has now ensured that the 41-time Ranji Trophy winner will reach the final.
Coach Amol Majumdar’s team scored 449 for four in the second innings till stumps, taking their total lead to 662 runs.
Jaiswal (181 runs), who scored his first century in the quarter-finals, has scored consecutive centuries in this match. He and Jaffer (127 runs) together blew up Uttar Pradesh’s weak attack.
Mumbai, already playing ahead of a lead of 346 runs, started the second innings with a score of 133 for one in the morning.
The young batting pair of Jaiswal and Jaffer again dominated the match. Jaffer must have certainly made his uncle Wasim proud with his performance.
Both the young Mumbai batsmen put up a 286-run partnership for the second wicket with several brilliant shots on the Uttar Pradesh bowlers.
Jaiswal hit 23 fours and a six in his 372-ball knock while Jaffer hit 15 fours and two sixes in his 259-ball knock.
Uttar Pradesh had to wait a long time to get their first wicket of the day. Fast bowler Shivam Mavi (1 for 36) ended the huge partnership by dismissing Jaffer in the 107th over of the innings.
But Jaiswal continued to play the shots as desired and did not spare any bowler. Jaiswal missed his double century, which was caught by Prince Yadav (2 for 69) by Aryan Juval.
Uttar Pradesh took two successive wickets of Suved Parker (22 runs) and Jaiswal but by then it was too late.
Uttar Pradesh tried nine bowlers to take three wickets on the day.
Left-arm spinner Saurabh Kumar (one wicket for 105 runs) was the costliest bowler, with Jaffer and Jaiswal scoring a lot of runs.
Sarfaraz Khan 23 and Shams Mulani were present at the crease for 10 runs till the stumps.
Now only on the last day it remains to be seen whether Mumbai will reach the final on the basis of win or first innings lead.
