The 16-year-old finished with impressive figures of seven for 107, including six of the seven Mumbai wickets to fall on the fourth and final day of the match, to help his side skittle out the hosts for 366 in their first innings.
Tamil Nadu scored 253 for 3 in their second innings, with Murali Vijay registering a majestic 118-ball 154, that comprised 20 hits to the fence and five over it.
Arun Karthik scored a patient 60, and his second wicket stand with Vijay yielded 168 runs for the visitors.
Mumbai's collapse was shocking considering they began the final day comfortably placed on 308 for three. Srinivas's brilliant spell meant they lost their last seven wickets for just 58 runs. The youngster, who had accounted for Ajinkya Rahane (98) on the third day, added the prized wicket of skipper Wasim Jaffer (141) to his kitty besides accounting for Abhishek Nayar (16), Ramesh Powar (0), Iqbal Abdullah (0), Dhawal Kulkarni (0) and Usman Malvi (4).
Ganapathy took the only other wicket to fall -- the day's first trapping Onkar Khanvilkar (22) up front after just six runs had been added to the overnight total.
With a result out of question, after the visitors had batted for almost two days to post 501 in their first innings, the best Mumbai could have hoped for was to take three points from the game on the basis of a first innings lead. Alas, they had to settle for only one.
The draw strengthened Tamil Nadu's lead at the top of Group A, with 23 points from six matches, while keeping Mumbai in third place with 16.
The defending champions play Gujarat in their final group match, starting Tuesday at the Brabourne stadium.
Brief scores:
Tamil Nadu: 501 (S Badrinath 250, C Ganapathy 126; D Kulkarni 3-93, U Malvi 3-108) & 253-3 (M Vijay 154).
Mumbai: 366 (W Jaffer 141, A Rahane 98; Aushik Srinivas 7-107).

Delhi beat Maharashtra by ten wickets
Delhi kept their quarter-final hopes alive after a comprehensive 10-wicket victory over Maharashtra in their fifth Ranji Trophy Super League Group B.
Their second successive victory gave Delhi six points, taking their overall tally to 15. Virat Kohli's side now needs to beat Bengal in their final group engagement to snatch a berth in the quarter-finals.
After Pradeep Sangwan's five-wicket burst reduced them to 334 for nine at stumps on Thursday, Maharashtra's innings folded after adding just 25 runs to the overnight total.
Parvinder Awana had Samad Fallah (28) caught by Aditya Jain to bring down the curtains on Maharashtra's innings.
Needing just 109 runs to win the match, Delhi romped home in just 17.1 overs, with Virat and Mithun Manhas combining for a 112-run unbeaten opening stand.
In-form Virat did most of the scoring, slamming 11 fours in his 58-ball 67.
Manhas gave him good support with a 49-ball 38, which included five hits to the fence.
Delhi's final league engagement is an away tie in Kolkata from December 15.

Railways bag three points from draw with Hyderabad
Hyderabad: T P Singh slammed a brisk century while V Cheluvaraj missed his ton by seven runs as Railways boosted their quarter-final chances with the three points they gained from a draw against Hyderabad in the Ranji Trophy Super League match.
Having posted 305 in their first innings, Railways restricted the hosts to 303 and that wafer-thin two-run first innings lead proved crucial in the Group A match, which ended in a tame draw on Friday.
Hyderabad got just one point from the outing.
Resuming their second innings on 18 for no loss, Railways got some batting practice in putting up 363 for five at stumps on the final day.
Faiz Fazal (49) and skipper Cheluvaraj (93) added 145 runs for the opening stand but both had the misfortune of missing individual landmarks.
Mohammed Khader first dismissed Fazal when the batsman was just one run shy of his fifty, and got the better of Cheluvaraj, Anirudh Singh taking his second catch of the day.
T P Singh and Yere Goud (72), however, made merry and remained not out.
Singh's unbeaten 105-ball 100 had eight fours and three sixes while Goud hit 12 boundaries in his unbeaten 86-ball knock.
Brief scores:
Railways: 305 (M Suresh 64; A Absolem 5-89) & 363-5 (T P Singh 100, Y Cheluvaraj 93, Y Goud 72; M Khader 3-65).
Hyderabad: 303 (A Rayudu 73, P Shashank Nag 51, S Bangar 4-91, K Upadhyay 4-93).
