NEW DELHI: Vice-captain Ravindra Jadeja, widely regarded as India's most valuable red-ball cricketer, underlined his all-round brilliance by following up an unbeaten century with a four-wicket haul as the hosts crushed the West Indies by an innings and 140 runs inside three days in the first Test at Ahmedabad, taking a 1-0 lead in the series.

After India declared their overnight innings at 448/5 with a massive 286-run advantage, the visitors fared even worse in their second outing, bundled out for just 146 in 45.1 overs. Jadeja was the standout bowler once again, finishing with figures of 4/54.

The second Test is scheduled to be played in New Delhi from October 10 to 14.

"Honestly, I think this was the perfect game for us. Three centuries, and we fielded really well so no complaints," skipper Shubman Gill said at the post-match presentation ceremony.

With the match and series firmly tilted in favour of the dominant hosts, India outclassed the struggling West Indies in every department on a surface that offered contrasting challenges across the three days.

On Day 1, the lively pitch aided the pacers, with Mohammed Siraj (4/40 and 3/31) and Jasprit Bumrah (3/42) making full use of the conditions. By Day 2, batting became easier, allowing India's batters to pile on the runs.

In the end, the hosts built a lead large enough to enforce an innings defeat, ensuring the script remained unchanged as they wrapped up a resounding victory in the first of their four home Tests this season.

Opener KL Rahul (100) ended his nine-year-long century drought at home, wicketkeeper-batter Dhruv Jurel (125) notched his maiden Test ton and Jadeja (104 not out) stretched his purple patch with the bat as India flexed batting muscle, condemning the West Indies for the hard grind to take wickets.

On Day Three, hoping to extract some assistance early in the morning India declared at their overnight total but it was the Jadeja-led Indian spinners who exploited the grip off the surface and rough patches to ran riot.

While Nitish Reddy’s athleticism handed Siraj the first wicket among pacers, it was Jadeja (4/54) who followed up his unbeaten ton with a three-wicket burst to initiate a swift end to West Indies’ plight, reducing them to 66/5 at lunch.

In fact, Jadeja, with his century and a four-for in the second innings, narrowly missed the feat of hitting a ton and taking a five-for in a Test, which he has done twice in the past.

Siraj then produced a two-wicket over post lunch dismissing Justin Greaves (25) and Jomel Warrican (0), shortly after Washington Sundar (1/18) caught-and-bowled the last of the recognised batters, Alick Athanaze, who batted well for his 38.

Kuldeep Yadav (2/23) took a sharp return catch of Jayden Seales (22) who had struck some meaty blows to bring an end to the game shortly after drinks in the second session.

Jadeja was menacing on a track offering turn as he ran through the West Indies top-order. While the left-arm spinner wrecked havoc in that frail batting order which fell like a pack of cards once again, Kuldeep Yadav (1/15) and Siraj (1/16) also had their share of contributions.

It all began with India’s declaration, which expedited the inevitability as only one result was possible given the state of the West Indies team.

And it did not take long for the floodgates to open.

Openers Tagenarine Chanderpaul (8) and John Campbell did began on a positive note but it was the brilliance of Nitish Reddy at square leg which produced the first breakthrough in the eighth over.

Chanderpaul, who pulled one short ball from Siraj, was left in disbelief when Reddy flung himself on his left and was parallel to the ground when he took the catch and landed back with the ball lodged firmly in his hands.

It didn’t take long for India to introduce spin and vice-captain Jadeja was overjoyed when Campbell (14) lobbed one straight to short leg in a meek display of batting from a Test opener.

Jadeja had his second when West Indies No 4 Brandon King (5) hung his bat out to poke at one spinning away from him, to be caught at the first slip by KL Rahul who took a good, low catch.

West Indies captain Roston Chase (1) was no match for Kuldeep's brilliance, who tested him with an array of variations before bamboozling him with one that was shorter in length and straightened and knocked down his off-stump.

It didn't take long for the fifth wicket to fall when the most dependable of the West Indies' batters Shai Hope, pushing himself at No. 6, cut one outside off from Jadeja but Yashasvi Jaiswal was simply brilliant at short third man to quickly move to his right and take a diving catch to extend West Indies' plight.
