Vinay Kumar five-for routs Vidarbha

Karnataka captain Vinay Kumar capped his return from injury with a second-innings half-century and five-wicket haul that sent Vidarbha crashing to a 189-run loss inside three days in Vadodara. The win took Karnataka to their third victory in four games, thereby topping Group B at the season's halfway mark.

On a 17-wicket day in 71 overs, Karnataka first crumbled from 108 for 3 to 209 all out. Set 301 for victory, Vidarbha were skittled for 111, with Vinay returning 5 for 28.

Left-arm pacer Shrikant Wagh (4 for 59) and Lalit Yadav ripped through Karnataka's lower middle-order, before Vinay rescued them with 56 from No. 8. He hit eight fours along the way to build the lead.

After top-scoring with the bat, Vinay returned to lead the bowling charge, by picking three of the first four wickets; Vidarbha slumped to 12 for 4 at one stage. Jitesh Sharma counter-attacked to make 61, before S Aravind and K Gowtham dismissed the tailenders to finish off the innings inside 37 overs.

Saurashtra dismissed Assam for 171 in Kolkata with Jaydev Unadkat taking six wickets, but not before Assam took a first-innings lead of 18.

Saurashtra started the day on 121 for 9 with Unadkat and Shaurya Sanandia adding 32 runs in the morning for a cumulative partnership of 46 runs for the final wicket - their highest in the innings. Unadkat's 46 helped creep their score up to 153 before Sanadia was dismissed by Dhiraj Goswami.

In the reply, Assam lost their first wicket in their second over and Unadkat's double-strike in overs 13 and 15 saw them stranded at 26 for 3. But a 52-run partnership between Arun Karthik and Swarupam Purkayastha for the sixth-wicket took them close to Saurashtra's score, before the former was dismissed for 57. Purkayastha was out the following over and then Unadkat and Jadeja cleaned up the tail to constrict Assam to a slender lead.

Saurashtra lost opener Avi Barot to Arup Das - his eighth scalp of the match - as they ended on 0 for the loss of one wicket at stumps.

Opener Ranjit Singh and Subhranshu Senapati helped Odisha to 244 for 2 after following-on against Rajasthan in Patiala. Their unbeaten partnership of 159 runs in 56.3 overs gave Odisha a 93-run lead before final day's play.

Beginning the day on 143 for 8 in their first innings, Odisha fell short of avoiding follow-on by one run as Pankaj Singh picked up the last two wickets to finish with 4 for 61 as they were all out for 172, chasing 343.

Odisha batted better in their second innings; opener Sandeep Pattnaik scored a 32-ball 40 before his partner Singh and Senapati - both of whom remained not out on 89 and 90 - steered Odisha to a significant lead while playing out the seven Rajasthan bowlers used in the innings.

Unmukt Chand reached his century and followed that up with another half-century as Delhi reached 165 for 1 in their second-innings at stumps against Jharkhand in Thumba after being asked to follow on.

Starting the day on 225 for 3, Chand and overnight centurion Rishabh Pant added 36 runs more before the latter was removed by Ashish Kumar. Chand fell one run later, but not before he had completed his eighth first-class ton earlier in the day. The last five Delhi wickets could add only 72 more runs as they were dismissed for 334, trailing by 159. Kumar and offbreak bowler Sunny Gupta returned with three wickets each.

In their second innings, Chand put on 109-runs with fellow-opener Dhruv Shorey before Gupta dismissed him for 63. Shorey continued, to post his third first-class fifty, and ended not out on 67 with Nitish Rana, at stumps with Delhi on 165 for 1, leading by six runs.
