Skipper Ajinkya Rahane and Shreyas Iyer struck tons as Mumbai routed Karnataka by 88 runs in their Elite Group A Vijay Hazare match here on Friday.
Asked to bat first, Mumbai posted a mammoth 362/5 in their 50 overs before bundling out Karnataka for 274.

Rahane, dropped from the Indian squad in white ball cricket, led from the front with his blistering 148-run knock at the M Chinnaswamy Stadium.
Rahane continued from where he had left in the last game.
The India Test vice-captain, who struggled for runs in England recently, hammered a listless Karnataka attack in his 150-ball innings containing 13 fours and three sixes.
He, along with young opener Prithvi Shaw (60), stitched a 106-run stand for the first wicket to lay the foundation of a big total.
Rahane then found an able partner in Iyer (110) as the two frustrated the opposition bowlers in their big 216-run second-wicket stand.
Iyer was more attacking as he struck five fours and had eight other hits over the fence.
Then Mumbai's slow left-arm orthodox bowler Shams Mulani got into the act as he returned with fine figures of 4-71.
His scalps were Mayank Agarwal (66), C M Gautam (12), Stuart Binny (1) and R Vinay Kumar (36).
Mumbai bowlers struck at regular intervals as it was an uphill task for Karnataka and they eventually folded up well adrift of the target.

Uttrakhand thrash Puducherry
A day after the Indian Cricket Board's crackdown on eight of their players, Puducherry crashed to a 65-run defeat to Uttarakhand in a plate group match of the Vijay Hazare Trophy one-day tournament here Friday.
The BCCI cancelled the registration of the eight players for flouting eligibility norms, weakening a Puducherry team that was was bundled out for 226 and falling way short of the 292-run target after opting to field.
Uttarakhand grabbed the initiative early to post 291 for seven with opener Karanveer Kaushal striking 101, while No. 3 Vaibhav Bhatt made 73 in a 173-run stand.

Sikkim responded positively with Nilesh Lamichaney's 123 from 145 balls (11x4, 2x6), and the opener added 99 with Faizan Khan (47).
Seth impressed with the ball too, breaking the partnership, as Sikkim choked in the big chase.
In Nadiad, Nagaland rode on wicketkeeper batsman K B Pawan's unbeaten 113 to register a thumping seven-wicket win over Meghalaya.

Lower down the order Yogesh Nagar remained unbeaten on 58 while Gurinder Singh struck 56 to help Meghalaya post 246 for six.
