Alex Hales and Luke Wright gave England a handy start with a half-century opening stand in the warm-up match against a Vice-Chancellor's XI at Sir Vivian Richards Stadium.
Hales and Wright each had a chance in the absence of rested one-day international captain Alastair Cook and Ian Bell to make a case as prospective 50-over openers.
In a match also notable as England's first since the controversial axing of record runscorer Kevin Pietersen from all future plans, the tourists reached 87 for two in 15 overs.
England were put in on a sunny morning but after overnight rain, and Wright was under way with a cut for four off Miguel Cummins from the second ball of the match.
He also pulled the same bowler, who made his international debut against Ireland last weekend, for six to bring up the 50 stand in the seventh over.
Wright appeared marginally the more assured of the opening pair until he lost a little patience against left-armer Raymon Reifer's line wide outside off-stump and smeared a catch to deep cover.
Hales was joined by Ben Stokes, and the number three hit his third ball from first-change Jonathan Carter over midwicket for four.
But 17-year-old seamer Alzarri Joseph, called into this match from outside the hosts' initial squad, had Hales mis-pulling to present him with a simple catch almost in the batting crease in his follow-through.
