Skipper Aditya Tare struck 154 to lead a fine lower-order rally and put Mumbai in command by posting 488 in their first innings on the second day of their Group B match against Tamil Nadu.
Tare, who resumed the days on his individual score of 69, was involved in a 123-run stand for the eight wicket with Shashank Attarde (58).
Tare hit 19 fours and 2 sixes during his 253-ball knock as Mumbai added 204 runs from 59 overs on Sunday from overnight 284 for 6.
In reply, Tamil Nadu were 66 for no loss with experienced opener Abhinav Mukund batting on 52.
The Tamil Nadu bowlers toiled for five sessions before wrapping up the Mumbai innings with ace off-spinner Ravichandran Ashwin (3/121) and left-arm spinner R Sai Kishore (4/125) sending down 47 and 46 overs respectively.
The Mumbai lower-order continued to make things difficult for the home side bowlers with Tushar Deshpande (39) smashing Ashwin for three huge sixes while No 11 Royston Dias too joined the fun, hoisting B Aparajith for a big one over long-on.
Double ton for pujara
Rajkot: Prolific India Test batsman Cheteshwar Pujara slammed 248, his 13th first-class double century to help Saurashtra post a massive 581 for 7 declared in Group B match against Karnataka.
Pujara, who on Saturday joined a select group of cricketing greats by smashing his 50th first-class century, is already the Indian player with most first class double centuries when he scored his 12th double ton in 2017 to go past Vijay Merchant.
With his 248 on Sunday, Pujara also became only the third player to record seven double centuries in Ranji Trophy. He is at joint second with Ajay Sharma two behind Paras Dogra, who played most cricket for Himachal Pradesh.
Pujara also completed 6000 runs in Ranji Trophy during the course of his marathon knock.
He and senior batsman Sheldon Jackson (161) rescued Saurashtra with a massive 394-run stand for the third wicket after they lost their two openers for only 33 runs.
Pujara resumed the second day on 162 and raised his double ton on Sunday before being eventually dismissed for 248 off 390 deliveries with help of 24 fours and a six.
In reply, Karnataka were 13 for 1 in eight overs.
Haryana bounce back
Rohtak: Left-arm spinner Tinu Kundu grabbed five wickets as Haryana staged a remarkable comeback to take an upper hand in Elite Group C match against Odisha.
Haryana, who were bundled out for a paltry 90 after electing to bat, bowled out Odisha for 160 and then replied strongly in their second essay by posting 218 for five, taking an overall lead of 148 going into the penultimate day.
Overnight 141 for five, Odisha lost their remaining five wickets with the addition of just 19 runs inside nine overs at the Chaudhary Bansi Lal Cricket Stadium in Lahli.
Haryana batted sensibly in their second innings with openers Shubham Rohilla (48) and Ankit Kumar (46) putting up a 101-run stand. Himanshu Rana also contributed at number five before Pramod Chandila and Patel saw through the day.
At the Barsapara Stadium in Guwahati, Assam replied strongly with 209 for three after Chhattisgarh posted 318 in their first innings, trailing the visitors by 109 runs with seven wickets intact.
Nagaland on top
Sovima: Wicketkeeper-batsman Yogesh Takawale slammed an unbeaten 117 as Nagaland batsmen made merry against the Arunachal Pradesh to pile up a mammoth 543 for seven declared in Plate group fixture.
Takawale’s knock from 162 balls, laced with 14 fours, came after No 3 Shrikant Mundhe top-scored for the team with 166 on the opening day at the Nagaland Cricket Stadium.
Mundhe also claimed three for 32 to leave Arunachal Pradesh reeling at 141 for four in 37 overs, trailing by 393 runs.
