Bowling coach <a href="https://www.cricketcountry.com/players/Courtney-Walsh">Courtney Walsh</a> has called for the need to show patience and invest more in the <a href="https://www.cricketcountry.com/teams/Bangladesh">Bangladesh</a>'s stock of young fast bowlers. <p></p> <p></p>Over the years, Bangladesh have tried many new combinations from <a href="https://www.cricketcountry.com/players/Taskin-Ahmed">Taskin Ahmed</a> and Kamrul Rabbi in 2017 to the most recent pair of <a href="https://www.cricketcountry.com/tag/Ebadat-Hossain">Ebadat Hossain</a> and Khaled Ahmed in the first Test against <a href="https://www.cricketcountry.com/teams/New-Zealand">New Zealand</a> but have each pair has ended up conceding way too many runs whenever the side has travelled abroad.

"Five or ten. Not as individuals, but as a group. But we can rotate them as well, play a couple together, where they get a good feel, a good understanding of what's happening. Especially in conditions away from home. In Bangladesh, sometimes, none might play or one might play, but when you're away from home, they need to play. <p></p> <p></p>"So it'll be nice for them to get a good run so they get a good feel of what's happening, and you can then judge to see how much they have learnt. We invested in Ebadat. If you remember, two years ago, he came as a developmental player. And that investment has sort of worked in terms of how he made his Test debut here. That's a good sign. If we can get that to continue, for him to play a couple of Test matches, and to keep improving." <p></p> <p></p>In Hamilton, Ebadat and Ahmed gave away 369 runs from 87 overs combined, picking up just one wicket, and while Bangladesh have been critical of the ineffectiveness of young fast bowlers leaking runs, Walsh underlined the importance of giving them a chance rather than chopping and changing too much. <p></p> <p></p>"I think the decision-makers have to be patient. It's something I have always advocated for. You have to give a guy a chance to play a couple of games and then if he hasn't proved his worth, you can make changes," he said. <p></p> <p></p>"If you're going to play one Test match here and one Test match there, you're never going to get a chance to learn the trade or improve your game. One Test match or two Test matches are not good enough. Obviously, when we're in Bangladesh, we know it's more spin-friendly, so when you're overseas you want to get a good run. Last tour, we had new fast bowlers. This one, the same thing. South Africa, the same thing. There's no continuity and consistency. We have to look at three-four guys that we think can make it, especially for overseas, and invest in them. <p></p> <p></p>"During the review meeting, they accepted where things went wrong and where it went well. Once the players admit and accept the discussions, to me it is a big plus. We look at where they did well, and where they need to improve, and that's my responsibility."
