Shivam Dube led India A's spirited comeback from 20 for five with an aggressive knock before pacer Sandeep Warrier struck thrice to leave West Indies A reeling in their second innings on day two of the second unofficial Test, in Port of Spain.
Dube (79 off 85) and opener Priyank Panchal (58 off 125) shared a 124-run stand for the sixth wicket after the batting collapse, taking India A to 190 all out in their first innings.
Pacer Chemar Holder was the stand out bowler for the hosts, taking five wickets for 54 runs in 12.5 overs and helping his team gain a healthy 128-run lead. However, West Indies squandered the advantage by losing their four wickets for 12 runs in the second innings.
At stumps, they led by 140 runs and if they manage to set a 200-plus run target, it will be a tricky chase for the Indians.
India A lead the three-match series 1-0.
Earlier, Test specialists Hanuma Vihari and Mayank Agarwal were dismissed cheaply leaving India A tottering at 11 for four in the first hour after West Indies A scored 318.
Agarwal (4), who wanted some game time before the Test series got a beauty from new ball bowler Holder, who bowled at a brisk pace and also extracted disconcerting bounce.
Holder got one to climb up from back of the length with a shade away movement that squared the Karnataka opener resulting in a nick behind the stumps.
Abhimanyu Easwaran (0) tried to punch one off backfoot but couldn't keep it down and was caught at point to give Holder his second wicket.
Skipper Vihari (0) also didn't trouble the scorer as Holder got one to nip back in and the ball also kept a bit low trapping him plumb in-font.
Anmolpreet Singh's lack of technique against quality pace bowling was exposed with Holder squaring him up with a bouncer as he fended awkwardly, to be caught at point.
This was after West Indies A starting the day at 243 for 5 could add another 75 runs before lunch with giant Rahkeem Cornwall (56 no off 70 balls) scoring bulk of the runs.
Leg-spinner Mayank Markande (3/79 in 20 overs) got a couple of wickets and so did pacer Mohammed Siraj (3/63 in 27 overs).
West Indies A 318 all out 12/4 in 7 overs.
India A 190/10 in 46.5 overs (Dube 79, Panchal 58; Chemar Holder 5/54).
