India B scored 309 for 7, with Abhimanyu Easwaran unbeaten on 143 and Baba Aparajith contributing 70 runs. Ankit Kamboj was the standout bowler for India C, picking up 5 wickets for 66 runs. India B now trail India C's first innings total of 525 by 216 runs.
Even as Abhimanyu Easwaran stood tall from one end to post an unbeaten 143 for India B, Anshul Kamboj ran through the batting unit to take 5 for 66 to give India C the advantage by stumps on day three in Anantapur. With one day of action remaining, India C are now favourites to claim the first-innings-lead points, with India B still 216 runs behind at 309 for 7.
Day three began with India B on 124 for 0. The opening pair of Easwaran and N Jagadeesan were looking to build towards overcoming India C's first-innings score of 525, but Kamboj struck in the day's fourth over, dismissing Jagadeesan for 70.
That triggered a slide that had India B sipping to 194 for 5, with each of those dismissals belonging to Kamboj. After getting Jagadeesan caught behind, the seam-bowling allrounder had both Khan brothers - Musheer (1) and Sarfaraz (16) - dismissed lbw, and then followed it up with the wickets of Rinku Singh (6) and Nitish Kumar Reddy (2). While Ishan Kishan caught Rinku off Kamboj, Reddy was out bowled.
However, Easwaran, from an overnight score of 51, could not be dislodged through the day. He brought up his 24th first-class century after lunch, and with the help of 12 fours and a solitary six finished the day seven short of his 150. With Washington Sundar (13), he added a 43-run sixth-wicket stand, and with Sai Kishore (21), he stitched a 46-run partnership for the seventh wicket.
The two promising lower-order partnerships were ended by Vijaykumar Vyshak and Mayank Markande respectively, while Rahul Chahar (18*), coming in at No. 9, saw off the last eight overs with Easwaran on a day when only 65 overs were bowled.
India B's middle-order crumble, which saw them lose 5 for 65, now leaves them with very slim chances of earning any points from this round two fixture. If India C take the last three wickets and claim the lead - which they are favourites to do - they will earn three points and be guaranteed to move to the top of the Duleep Trophy table. India C's best-case scenario, though, would be to enforce follow-on early on the final day and then hunt for the six points on offer for an outright win.
