Turn 50s to 100s - Windies assistant wants batsmen to convert starts to centuries in England series

West Indies' assistant coach Roddy Estwick says conversion is the only real concern among the batting unit in the Windies camp ahead of the crucial third and final Test at Old Trafford.

The West Indies still have a glorious opportunity to win their first Test series in England since 1988 with the current battle locked at 1-1.

West Indies prevailed in the first Test, courtesy of some great performances from Jason Holder, Shannon Gabriel and Jermaine Blackwood. In the second Test, however, Ben Stokes led a superb comeback against the visitors to give England a comfortable 113-run victory.

With the bowlers holding their own in the series, Estwick says the batters must come to the party if they are to retain the Wisden trophy. However, he doesn't believe this is the right time to be chopping and changing with the series on the line.

FIVE HALF-CENTURIES

"I don't think there is concern in terms of their form because we think the batters are hitting the ball quite well and getting into good positions. The concern is that people have gotten starts and not gone on to get big hundreds, and that's been the difference," said Estwick.

The West Indies scored five half-centuries in the second Test, with Kraigg Brathwaite's 75 in the first innings being the highest score.

Only four batsmen have tallied over 100 runs in four innings thus far, with Shamarh Brooks leading the way with 169 with two half-centuries. Jamaican Jermaine Blackwood has so far scored 162 runs, also with two half-centuries, while opener Brathwaite and Roston Chase are the other batters with 100-plus runs.

The form of Jamaican opener John Campbell and Shai Hope has been put under the microscope, with both players averaging 17.33 and 14.25, respectively. Only Kemar Roach and Shannon Gabriel have worse averages in the series.

In the meantime, Estwick added that Rahkeem Cornwall stands a chance of making it into the side. The West Indies are expected to largely name the same squad from the last Test, barring injuries.

"We'll have a look at it - he'll come under discussion, I'm sure. Rahkeem has been preparing well so if he's given the opportunity, I'm sure he will go well. We'll try to make sure we get the best combination from those 15," said Estwick.
