Ashwin, Saha tons propel India

Ravi Ashwin posted a fourth century in nine innings against the West Indies and Wriddhiman Saha made his maiden hundred as India recovered from 5-126 to make 373 on day two of the third Test in St Lucia.

In reply, the run-out of opener Leon Johnson (23) was the only blemish on an otherwise perfect start for the Windies, who made it to 1-107 at stumps, with Kraigg Brathwaite (53) and Darren Bravo (18) the not out batsmen.

Resuming on 5-234 overnight, Ashwin made 118 and wicketkeeper-batsman Saha added 104 before India collapsed in the second session.

Resuming after lunch on 5-316, the tourists soon lost Saha, caught behind off the bowling of teenage debutant Alzarri Joseph, and the dismissal triggered a lower-order collapse as India lost five wickets for just 14 runs to slump from 6-339 to 353 all out.

Ravindra Jadeja (6), Bhuvneshwar Kumar (0) and Ishant Sharma (0) all fell within minutes of each other as West Indies tore through India's tail end.

Among the bowlers, Miguel Cummins finished with 3-54, a haul that included Ashwin's wicket after the batsman completed his second century of the series, Joseph took 3-69, and Shannon Gabriel and Roston Chase chipped in with two wickets apiece.

Having batted through nine overs to reach tea without loss, the West Indies top order remained patient in the evening session.

Johnson, who replaced Rajendra Chandrika in the West Indies line-up, was punished for attempting a risky single as he was run-out with a direct hit from Lokesh Rahul.

With rain expected over the next two days, the chances for both teams to move into a winning position may be limited.

India leads the four-match series 1-0.

Ashwin is one of just six Indian batsmen to post four or more hundreds against the West Indies in Test history, the off-spinning allrounder boasting a far superior hundreds-per-innings ratio to the other five to have achieved the feat.
