New Delhi, Oct. 17 -- Jammu and Kashmir skipper Paras Dogra led from the front with an unbeaten 112, lifting his team from 32/3 to 273/7 by stumps, though Mumbai remained favourites for a first-innings lead in their Ranji Trophy encounter in Srinagar. At the Sher-I-Kashmir Stadium, Mumbai folded up for 386 after resuming Day 2 at 336/5. Seamer Yudhvir Singh (5/96) denied Shams Mulani (91) a maiden ton and also took out Shardul Thakur for a duck. Shardul, though, struck in the first over of the J&K innings to remove Shubham Khajuria. Debutant Irfan Umair also picked up his first wicket but the hosts, led by Dogra, recovered from the shaky start. All five Mumbai bowlers were in the wickets' column, with Tushar Deshpande and Tanush Kotian taking two wickets each. At the NexGen Cricket Ground, Ayush Doseja announced his first-class cricket arrival in style, becoming the first Delhi batter to score a double century on debut - a commanding 209 off 279 balls against Hyderabad. "I always wanted to represent Delhi at the senior level and today that aim is complete.I didn't know that there were very few to have scored a double century on debut," Doseja told HT after the end of day's play. "I wasn't satisfied when I reached the hundred-run mark, I wanted to play a long innings. After 150, I started to feel comfortable and so started to play my shots and suddenly, I realised I was in the 190s, that's when I decided to play more sensibly for a bit. "I wasn't satisfied even after the double century but I felt really happy because it was my first ever double century. I hadn't scored a double even in age group cricket. I am just thankful to everyone who was with me through my journey." Doseja's cricketing journey began at the age of six. Determined to make his mark in Delhi's fiercely competitive circuit, the 23-year-old from Rohini has honed his skills under Ajay Choudhary at Ravi Brothers Club - who continues to coach him. Initially, Choudhary felt he was too young and advised him to join another academy. Doseja thus moved to Uday Maan Cricket Academy before returning to Choudhary at 14, where he began playing in the senior DDCA league. On what turned out to be a batting-friendly track, Doseja and opener Sanat Sangwan (211*) took full advantage. Their 319-run stand helped Delhi declare at 529/4 in their first innings against Tilak Varma-led Hyderabad. Coming together at a tricky 113/3, the duo steadied the innings before putting Delhi in complete control. The double ton capped off a strong start to the season for Doseja, who has been working on becoming an all-format batter. Earlier, he had impressed for West Delhi Lions in the Delhi Premier League, scoring 300 runs at an average of 42.86, including a century. Elsewhere, in Coimbatore, Ishan Kishan converted his unbeaten ton from Day 1 into 173, steering Jharkhand to 419 in their first innings with Sahil Raj (77 off 183) offering support in a 214-run partnership. Tamil Nadu are reeling at 18/5 in reply. In Bengaluru, Vidarbha opener Aman Mokhade also fell short of a double, dismissed for 183 on Day 2, but lower-order contributions carried his team to 463 against Nagaland. At Green Park in Kanpur, KS Bharat (142) and Shaik Rasheed (136) fell short of the doubles but took Andhra Pradesh to 470 against Uttar Pradesh. In Indore, Madhya Pradesh captain Rajat Patidar struck an unbeaten 107 against Punjab on Day 2, helping his side secure a 73-run lead.
