Jamaica's senior men's cricket team head coach, Junior Bennett, wants to see an improvement in the concentration levels of batsmen.
Heading into yesterday's third regional Super50 trial match at Sabina Park, the island's batsmen were yet to score a century after two trial matches.
Only two players, 21-year-old opener Kennar Lewis and Nkrumah Bonner, had got half-centuries.
Lewis scored 94 in the first match last Friday, while Bonner made 68 in the second, which was played a day later.
"I'm looking for an improvement in the performance of the batsmen," Bennett told the Jamaica Gleaner newspaper.
"In the first two matches, some people got starts but failed to carry on and make centuries.
"It's just two matches so far, but we have to remember the tournament is just a matter of weeks away.
"We need people to concentrate for longer periods and show that they can make big scores."
Among the players who have gotten starts but failed to push on are Tamar Lambert, David Bernard Jr., Danza Hyatt, Horace Miller, Paul Palmer Jr, John Campbell, Andre McCarthy and Yannick Elliott.
In the first game, Lambert made 40, Miller 25, Hyatt 39, Palmer Jr 29, while David Bernard Jr scored 29, Campbell 38, McCarthy 27 and Elliott 21 in the second encounter.
Off-spinner Jamie Merchant made unbeaten knocks of 31 and 21 in both fixtures, while leg-spinner Damion Jacobs made 22 not out in the first.
Bennett, meantime, said he was pleased with the effort of the bowlers thus far.
Young fast bowler Brian Buchanan claimed three for 40, Andrew Richardson two for 14 and Jacobs and left-arm spinner Patrick Harty Jr claimed three for 26 and three for 30, respectively, in the first match.
In the second, Harty Jr took five for 26, leg-spinner Akeem Dewar took three for 44, Lambert two and Buchanan two for 36, to finish as the leading bowlers.
"The fast bowlers have been bowling fairly good line and lengths, while the spinners are bowling in the right areas," Bennett assessed.
The 14-man squad for the Super50, which bowls off in Trinidad and Tobago on January 30, is set to be named on Friday, following the fifth and final trial match.
