Resuming at 168 for nine, the hosts lost last man Shahnawaz by adding two runs and set a winning target of 318 but visitors could notch up only 233 despite the splendid effort of Dheeraj Jadhav who compiled a defiant and unbeaten 124.
N P Singh was the wrecker-in-chief who accounted for six wickets for 87 runs on a chilly day and hosts opened their account in Group B with four points while Maharashtra is yetto add a point to its credit.
Dheeraj looked aghast as he lost partners at the other end with quick frequency and the team was reduced to 3 for 39 before skipper Hrishikesh Kanitkar (15) and Kaushik Aphale (16) provided some support to the opener.
Dheeraj's patient knock of 124 was the result of his 319 minute stay at the wicket with eleven fours and one six from the 215 balls he faced and carried the bat.
Keeper Satyajit Satbhai (43) joined Dheeraj to script a 58-run fifth wicket partnership and lift the score to 165 before N P Singh ripped through the lower order and bundledthe visitors out for 233.
Besides N P Singh, debutant Fahad Shahnawaz took two wickets for 34 runs while Daniel Manohar and Venkatapathi Raju claimed one wicket apiece.
