Yashasvi Jaiswal and Armaan Jaffer clobbered stunning centuries as dominant Mumbai put Uttar Pradesh on the back-foot by taking their overall lead past the 600-mark on Day 4 of their Ranji Trophy semi-final on Friday.
It was a run-feast on day four as the two batted with authority and it is almost certain now that the 41-time Ranji Trophy winners would sail into the summit clash.
The Amol Mazumdar coached side, in their second essay, was poised at 449 for four when stumps were drawn and had an overall lead of staggering 662 runs. Jaiswal (181), who has hit his maiden hundred in the quarter-final, slammed back-to-back centuries in the current one, as he and Jaffer (127), bulldozed a list-less Uttar Pradesh attack.
Mumbai, which already had a lead of 346 runs, began on their overnight score of 133 for one. And it was sheer dominance by their young batting duo of Jaiswal and Jaffer, who would surely have made his uncle Wasim proud, by his stellar performance.
The two young Mumbai batters, who started the day when they were in their 30s, pummelled the UP attack into submission with a variety of strokes on display in their 286-run stand for the second wicket.
It was raining boundaries at the Just Cricket Academy as Jaiswal hammered 23 fours and one maximum in his 372-ball innings, while Jaffer smashed 15 fours and two sixes in his 259-ball knock.
Uttar Pradesh had to wait long for getting the first-wicket of the day and pacer Shivam Mavi (1/36) dismissed Jaffer in the 107th over of the innings, to break the mammoth stand.
But that did not deter Jaiswal, who kept playing shots at will and spared no bowler. Jaiswal missed a richly deserved double-hundred as he was caught by Aryan Juval off Price Yadav (2/69).
UP did get two wickets in quick succession, that of Suved Parkar (22) and Jaiswal, but till then the damage was done. The wide gulf between the two sides was on display. UP used as many as nine bowlers, but managed to get only three wickets in the day.
Left-arm spinner Saurabh Kumar (1/105) had the most expensive figures as he was taken to task by Jaffer and Jaiswal.
At stumps, Sarfaraz Khan (23 not out) and Shams Mulani (10 not out) were holding fort. The only interest left on the fifth and final day is to see if Mumbai win outright or go through on the basis of first-innings lead.
