Chasing a target of 144, North Zone overcame minor hiccups before scoring the required runs in 22.5 overs on the fourth and final day of the league match here at the Usharaje Stadium.
North lost its openers Gautam Gambhir (6) and Virender Sehwag (16) cheaply and were reduced to 36 for four at one stage before Yuvraj joined forces with Dinesh Mongia (52, 4X9) to steer the team to victory with an unbeaten 100-run stand for the fourth wicket.
Both Mongia and Yuvraj were in a punishing mood as they flayed the bowlers all round the park at will. Mongia hit nine fours while Yuvraj hit seven boundaries besides four mighty sixes.
Yuvraj slammed 20 runs in what turned out to be last over of the day, hitting a hapless M R Srinivas to two fours and two sixes to finish off the innings in style.
Earlier, resuming at the overnight score of four for no loss, Gambhir and Sehwag could add just eight runs to the total when Laxmipathy Balaji trapped Gambhir leg before in the third over.
Vinay Kumar then claimed the wicket of Sehwag, who was caught by Sunil Joshi in the fifth over. North got another blow when Akash Chopra was clean bowled by Balaji. However, Mongia and Yuvraj then took the reins in their hands to take their team to victory.
