Rain stole the show during the first two days of the Americas Cup in Argentina and threatens to "earn" a hat-trick today.

It's a situation, says Bermuda cricket coach Mark Harper, that could result in organisers having to alter the tournament format to ensure a winner.

Not a ball was bowled in any of the three matches scheduled for the opening day on Saturday and again yesterday both the Bermuda-Canada and Cayman Islands-Bahamas clashes were thwarted before play could start. The United States and Argentina began their match but eventually suffered the same fate.

Today, originally the first of two rest days, will be used to contest Saturday's matches while Thursday - the second rest day - will now be utilised to play yesterday's games.

However, if play is washed out any other day, then it's unlikely the five round-robin phases could be completed in time for the final, scheduled for Saturday between the top two teams.

"It's been rain, rain and more rain. There was a lot yesterday and more last night. Today looked promising but just after 1 p.m. (noon Bermuda time) the place got very dark and we had a big thunderstorm. It's very doubtful for tomorrow," said Harper from the team hotel in Buenos Aires.

"The forecast is for rain again and if play is rained out again - which is very likely - it could be touch and go. That would only allow four rounds of competition."

Another concern for all teams, he noted, was that tournament regulations stipulate an entire round of matches will only be rescheduled if none of the games on a particular day achieve a result. If there is a winner in at least one match then the round will be considered played regardless of wash-outs in other matches on that day.

"It's just tough luck for those teams whose games are washed out but when you have a tournament as compact as this you don't have a lot of time to manoeuvre," he said.

Harper, who has seen rain spoil cricket on countless occasions in his native Guyana, described the situation as "frustrating" but added that Bermuda's cricketers were trying to stay focused on their goals.

"The guys are very disappointed. They were really looking forward to this tournament. We have daily team meetings and we've been working out. At the ground today we did some warm-ups and fielding and some guys had batting practice," he said.

Regarding team selection, he disclosed that Jacobi Robinson was sidelined with a groin injury during Friday's practice and that Sammy Robinson and wicket-keeper, Jekon Edness, were omitted from the final XI for Saturday's washed-out opener against the hosts.

"We were going to use (Chris) Foggo as the wicket-keeper and that same team was going to play today (yesterday)," he said.
