Mumbai closed in on a big win despite Odisha's stoic resistance with the bat as the defending champions reduced the visitors to 126/5 at stumps on Day Three after imposing follow-on, in their Ranji Trophy Group A encounter here on Friday. Odisha were trailing by another 191 runs as a defeat by an innings loomed large despite their stoic resistance making Mumbai toil here at the Sharad Pawar Cricket Academy Ground. Resuming at 146 for five in reply to Mumbai's massive 602 for four declared, Odisha made the Mumbai bowlers work hard for nearly 95 overs in the first innings, and after Ajinkya Rahane asked them to follow-on as the hosts took a 319-run lead, the response was no different.
