St John's (Antigua), Nov 27 : Four key West Indian cricketers -- Andre Russell, Shimron Hetmyer, Lendl Simmons and Evin Lewis -- will not be touring Pakistan for a six-match white-ball series later this year, and have cited personal reasons for pulling out of the Caribbean team. The Cricket West Indies (CWI) selection panel has named four uncapped players -- Shamarh Brooks, Justin Greaves, Gudakesh Motie and Odean Smith -- in the squads for the tour, beginning on December 13 with the first T20 International at Karachi. The tour comprises three T20Is and an equal number of One-day Internationals and will conclude on December 22. All the matches will be played at the National Stadium in Karachi. For the ODIs, newcomers Justin Greaves and Shamarh Brooks are batters, while Gudakesh Motie is a left-arm spinner. Odean Smith is a fast bowling all-rounder. Smith and Motie have also been selected in the T20I squad for the first time, along with left-arm fast bowling allrounder Dominic Drakes. Motie was a travelling reserve during the recent ICC T20 World Cup in the UAE, while Drakes and Smith were net bowlers before the start of the tournament. CWI chief selector, Roger Harper said following the announcement of the squad that, "There are a number of talented newcomers in each format that will have the opportunity to show what they are capable of at the international level. Justin Greaves is a very talented player, had a good CG Insurance Super50 tournament and performed well in the President's XI match against Ireland in 2020. Odean Smith grabbed our attention in the last CPL (Caribbean Premier League). His pace was never in question, however he has added greater control and has displayed the ability to be a wicket-taker. "Shamarh Brooks batted well in the CG Insurance Super50 Cup and followed that up with good performances in the CPL. He will lend greater depth to the batting line-up. Gudakesh Motie has been rewarded for his outstanding performance in the CG Insurance Super50, followed up by his showing in the CPL. Dominic Drakes has the potential to be an outstanding all-rounder as he displayed during the last CPL," said Harper. The ODIs in Pakistan are part of the ICC ODI Super League where points gained would work towards qualification for the ICC World Cup 2023. The ODI series will be West Indies' fourth of 12 in the ICC Men's Cricket World Cup Super League in which the top seven teams can secure automatic qualification for the Cricket World Cup 2023 in India. West Indies currently lie in eighth position out of 13 teams and have the opportunity to move above Pakistan into seventh position.
