Spinner Kuldeep Yadav starred in India's five-wicket win over West Indies in the first Twenty20 international on Sunday as the tourists struggled with the bat yet again on the tour.
Yadav returned figures of 3-13 with his left-arm wrist spin as West Indies managed just 109-8, their lowest T20 total against India, after being invited to bat first in Kolkata.
Wicketkeeper-batsman Dinesh Karthik then made an unbeaten 31 to anchor India's tricky chase. They reached their target in 17.5 overs and lead the three-match series 1-0.
"Exceptional performance with the ball. Was a lot on offer for the seamers. Even with spinners, it wasn't easy. Overall there was little bit for every department," skipper Rohit Sharma said after the win.
"To start with, we bowled well -- good areas. Used the conditions perfectly. Knew the chase wasn't going to be easy. Hopefully we can learn from these mistakes."
Debutant fast bowler Oshane Thomas removed the openers with just 16 runs on the board to give his team hope of defending their modest total.
Thomas got Sharma caught behind for six to pick his first T20 scalp and then bowled the left-handed Shikhar Dhawan for three.
Skipper Carlos Brathwaite stepped in to get two more batsmen trudging back to the pavilion as India slipped to 45-4.
"Oshane Thomas is a really exciting talent without doubt, good height plus that jump he takes, if he bowls in the right areas, it won't be easy for any batsman in the world to counter that," Sharma said of the 21-year-old Thomas.
Karthik and Manish Pandey, who made 19, put on an unbeaten 38-run partnership for the fifth wicket to put the chase back on track.
Debutant Krunal Pandya had a memorable debut after he hit the winning runs on his way to an unbeaten 21. He also picked up a wicket in the West Indies innings.
But it was Yadav who led an inspirational bowling attack that made West Indies lose their top five batsmen inside 11 overs.
Pandya got the big-hitting Kieron Pollard out for 14 with his left-arm spin to celebrate his maiden international wicket.
Kuldeep soon took over to get three key wickets including Brathwaite for four.
Fabien Allen hit a 20-ball 27 in his first T20 game for the West Indies before falling to another debutant Khaleel Ahmed.
It was Ahmed's first T20 wicket after the 20-year-old made an impression in India's 3-1 triumph over the visitors in the one-day internationals.
The tourists had suffered similar batting collapses in the Test series, which they lost 2-0, and in the ODIs. They were skittled out for 104, their lowest ODI total against India in the final match.
"I don't think we applied ourselves. We were either too defensive or too attacking. We could've scored 130-140, which would've been a winning total," said Brathwaite.
"As young bunch of guys, we want to be fearless."
The second T20 is in the north Indian city of Lucknow on Tuesday.
