Repeatedly overlooked for the Indian team, Prithvi Shaw made a statement with a blistering 61-ball 134 and powered Mumbai to a 61-run victory over Assam at the Syed Mushtaq Ali Trophy here on Friday.
The blazing knock came close on the heels of the batter expressing his disappointment at not being picked in India's ODI squad for the recent South Africa series at home.
In the Group A match, Mumbai put up an imposing 230 for three after being asked to bat first.
Shaw did the bulk of the scoring, striking 13 fours and as many as nine sixes at the Saurashtra Cricket Association Stadium.
In reply, Assam were bowled out for 169 in 19.3 overs. Tushar Deshpande was the most successful bowler for Mumbai, picking up 3/25 while there were two wickets apiece for Shams Mulani, Aman Hakim Khan and Tanush Kotian.
Captain Mayank Agarwal hit 47 and Manish Pandey struck 42 as Karnataka thrashed Meghalaya by nine wickets in a Group C match.
Electing to bat, Meghalaya could muster only 89 for 8 in their allotted 20 overs, thanks to double digit scores from Larry Sangma (34) and Yogesh Tiwari (22).
Vijaykumar Vyshak was the pick of the bowlers for Karnataka, registering figures of 3 for 5 from his four overs.
Chasing the modest total, Devdutt Padikkal perished in the fourth ball for a duck.
But, Agarwal and Pandey joined hands and stitched match-winning 90 runs for the comfortable victory.
In another Group C match, Kerala defeated Haryana by three wickets.
Elsewhere in the group, Services crushed Arunachal Pradesh by nine wickets while Maharashtra defeated Jammu and Kashmir by three wickets.
Fancied Tamil Nadu crushed Sikkim by nine wickets in their Group E match.
Batting first, Sikkim were all out for 79, and in response, Tamil Nadu completed the formalities with more than 10 overs to spare at the Ekana Cricket Stadium B.
Former India U-19 pacer Shivam Mavi grabbed 4/14 as Delhi hit a low, getting all-out for 99 as Uttar Pradesh were back to winning ways with a eight-wicket victory in a group B match.
It was a contrasting performance from both sides as UP lifted their game after a humiliating defeat at the hands of minnows Tripura while Delhi had out-batted Punjab, courtesy Nitish Rana's 55-ball-100.
The switch from Mumbai to Goa is working well for young Arjun Tendulkar as he kept up his consistent show with a career-best figures of 4/10 but his team lost to Hyderabad by 37 runs in another group B encounter at the Sawai Man Singh Stadium.
Left-arm fast medium pacer Tendulkar's scalps included his former Mumbai Indians teammate Tilak Verma (62) as Hyderabad scored 177/6. Tanmay Agarwal, with 55, was the other significant contributor.
In reply, medium pacer Ravi Teja took 4/20 as Goa were restricted to 140 in 18.5 overs.
