Guyana batsman Leon Johnson and Jamaica all-rounder Brendan Nash will make their debut for West Indies in an international one-day cricket tri-series with host Canada and Bermuda. Johnson, who turned 21 last Friday, was a former West Indies Under-19 captain with a modest record, while Australian-born Nash has forced his way in after returning in 2007 to his parents' country, Jamaica, and enjoying sound returns at first-class and limited overs level. The squad will be led by Chris Gayle but weakened by the absence of key all-rounder Dwayne Bravo and experienced batsman Shivnarine Chanderpaul. Bravo was nursing an ankle injury while Chanderpaul was allowed to complete his summer contract with English county Durham. Wicketkeeper Carlton Baugh Jr., out of favor for the past two years, was chosen instead of incumbent Denesh Ramdin and Ramdin's most recent understudy, Patrick Browne. Squad: Chris Gayle (captain), Xavier Marshall, Ramnaresh Sarwan, Leon Johnson, Brendan Nash, Shawn Findlay, Carlton Baugh, Sewnarine Chattergoon, Nikita Miller, Dave Mohammed, Jerome Taylor, Fidel Edwards, Daren Powell, Kemar Roach.
