Kuldeep Yadav (5-82) and Ravindra Jadeja (3-46) produced magical spells to help India wrap up West Indies’ first innings at 248 in the ongoing second Test between two sides at Arun Jaitley Stadium, Delhi.

Having gained a massive lead of 270 runs, India skipper Shubman Gill decided to enforce the follow-on. However, the tourists were quite impressive in their second innings.

Riding on John Campbell (87*) and Shai Hope (66*), West Indies reached 173/2 at stumps on Day 3, still needing 97 more runs to make the hosts bat again.

Addressing the media at the end of third day’s play in Delhi, India’s assistant coach Ryan ten Doeschate admitted that their spinners will have a tough fourth day in office with the pitch getting slower.

"We thought the wicket was going to keep deteriorating and by close of play it would be at its worst. It just seems to have slowed down even more. It's quite challenging to get any pace up," ten Doeschate told reporters.

In fact, he supported what Ravindra Jadeja had said at the end of second day that tweakers will have to use more shoulder to get bounce and zip off the surface.

However, the Dutchman feels that it is double edged sword which can at times prove to be counter-productive. "Like I said, you have to really fire the ball in. Of course, when you fire the ball in, it's got less chance of spinning. So, we have had a tricky afternoon," he said.

"Obviously, monitoring speed is probably the one thing you can play with. You saw every time Washy (Washington) bowled a little bit slower, you get a little bit more turn. Obviously, the batter has a bit more time. So, it's striking the batter and using the changes in pace to get a mistake out of the batter," he explained.

Ryan ten Doeschate was all praise for left-handed batter Campbell, who swept with a lot of ferocity en route his unbeaten 87.

"It's just got to be super patient. Obviously, Campbell has swept very well. So, it's another thing tactically we can look at. Sometimes we expect a lot from our bowlers and sometimes the wickets are a bit unresponsive."

Despite Kuldeep claiming five wickets in the first innings, it was Jadeja, who shared the new ball along with Mohammed Siraj in the second innings.

Asked to explain the logic behind such a decision, ten Doeschate said, "Yeah, I'll be honest. The thinking there was the hardness of the ball. So we felt Kuldeep still extracted some spin towards the back end of the first innings.

"We just felt one of the finger spinners going with the new ball maybe it would just grip a little bit more. So we sacrificed the mystery part of it for someone who is hopefully going to get a bit more bite out of the pitch with the finger spin. And that was the thinking that worked out."

Ryan ten Doeschate said there was toss up between Washington Sundar and Jadeja for the new ball. "There was a deliberation with whether Washi or Jaddu would take the new ball. Obviously one of the seamers bowling from the other end. And Shubman obviously decided to go with Jaddu," he said.

While Kuldeep has still gone wicketless in second innings so far, ten Doeschate felt that had a few umpires' call against both Campbell and Hope gone their way, things would have been different.

"I think, obviously, the difference with Kuldeep is he's a mystery spinner and he's not the easiest to pick. So, I think that buys him a little bit more. He has an element of danger compared to the finger spinners. But, also, I don't think we're a million miles off this afternoon, not to point things at our pipe at all," he said.

"But, there are three very close decisions there. If you can even two of those, it's a much better day for us. But, yeah, Kuldeep put the ball in the right area and spun it both ways."

The assistant coach reckoned that the margin in terms of lines bowled and lengths hit by Kuldeep between first and second innings was minimal.

"You can see how small the margins are and how he got the wickets in the first innings. It's just play and miss compared to getting an edge and not getting wickets. But, I certainly think the fact that a lot of these guys wouldn't have faced more of him, but still, you know, that mystery element makes him a little bit more effective than the other two."
