Skipper G Hanuma Vihari (169) and K.S. Bharat (105) starred for Andhra as the triumph enabled them to finish on top of the standings with 24 points and qualify for the national knockout phase, along with Mumbai, which finished second with 16 points.
Vihari and Bharat stitched together a massive 254-run partnership in 204 balls, propelling Andhra to a mammoth 344/5 in 50 overs before restricting the opponents to 315 for 9 despite Siddhesh Lad's strokeful ton.
Left-arm spinner R Sai Kishore took five wickets, his first in List 'A' cricket.
In the other match of the day, wicketkeeper Keenan Vaz snared seven victims (six catches and a stumping) to equal the record of Mahesh Rawat and Parthiv Patel in List A matches as Goa edged Gujarat by one wicket in a humdinger.
After putting a decent 296 runs on board while batting first, Jharkhand wrapped up J & K for a paltry 199 in 46 overs.
Saurashtra edged out Vidarbha on a better net run-rate for the second spot.
In Group A, Manan Vohra's strokeful 143 went in vain as Punjab were derailed in their bid to make the knockouts, with a four-wicket defeat at the hands of Railways.
Opting to bat first, Vohra played a brilliant knock of 143 off 148 balls laced with 13 fours and two sixes. He was well supported by skipper and India veteran Yuvraj Singh (35) as Punjab posted 280/8 in 50 overs.
In reply, Railways rode on Arindam Ghosh's unbeaten 89 to gun down the target in 49.2 overs.
In another game, group leaders Baroda continued their purple patch by confirming their place in the playoffs with a 57-run win over lowly Odisha.
In reply, Odisha could only manage 260 all out with Biplab Samantray (74) top-scoring and Prayash Singh scoring 51.
For Baroda, Atit Seth, Lukman Meriwala and Ninad Rathwa all took two wickets each.
