Pakistan negotiated a potentially tricky first session, reaching 70 for one on the first day of the third and final Test against the West Indies at Windsor Park in Dominica on Wednesday.

After they were put in to bat, Shan Masood was the tourists' only casualty of the morning, falling to off-spinner Roston Chase after an hour's play.

Opening partner Azhar Ali (36 not out) was set to resume after the interval alongside Babar Azam (24 not out), their partnership having already produced 51 runs for the second wicket.

West Indies' faster bowlers failed to make the inroads that Jason Holder would have hoped for after he won the toss and had no hesitation in putting the opposition in to bat in heavy, overcast conditions.

While Shannon Gabriel, the destroyer of the Pakistanis on the final day of the second Test, used the new ball with accuracy and economy, Alzarri Joseph lacked control, forcing the captain to introduce himself and then Chase in the quest for the breakthrough.

It came when Masood, playing his first match of the series in place of the unwell Ahmed Shehzad, reached nine off 30 deliveries and prodded indecisively at a delivery from Chase for Holder to take the straightforward catch at second slip.

Having failed to score in both innings of the second Test, new batsman Azam found the bowling to be much less challenging than at Kensington Oval and settled into the promising partnership with Ali.

Despite an effort dominated so far by caution, Ali latched on to two loose deliveries from Chase, hoisting them for sixes to highlight an otherwise quiet morning.

With a 106-run win in Barbados levelling the series, the home side named an unchanged eleven in pursuit of a first Test series win for five years against a team ranked higher than themselves.

Apart from the recall of Masood, fast-medium bowler Hasan Ali is making his debut at the expense of leg-spinner Shadab Khan, who struggled in his first appearance in the second Test.

Pakistan have never won a Test series in the Caribbean on seven previous tours.
