On a day when bad light forced calling off play atleast ten minutues ahead of the schedule, Mumbai had gained 51 runs first innings lead over Karnataka, which had slumped to 186 runs in their first knock on the opening day.
Indulkar, who was harsh on Karnataka bowlers at times, smashed fourteen boundaries facing 209 balls in 240 minutes.
Mumbai after losing the wicket of Wasim Jaffer (2/103), who contributed a valuable 62 runs reaching the fence twelve times, came under stress as it lost two more wickets of Amol Mazumdark and Nishit Shetty for just addition of six runs.
Amol Mazumdar (1) and Nishit Shetty (4) fell victim to Sunil Joshi and Udit Patel respectively.
Indulkar, playing a cautious knock, not only kept the scoreboard moving but arrested further damage to his side.
When play was called off, Indulkar and Khanvilkar were batting on 117 and 23 respectively.
Brief Scores: Mumbai 237 for the loss of four wickets in 90.2 overs. Indulkar 117 batting and Omkar Khanvilkar 23 batting. Udit Patel 2/60, Sunil Joshi 1/75.
