COSTA RICA-JAMAICA June 20 in Alajuela TV: ISM (closed-circuit), live, 10 pm ET. Referee: John Toro Rendon (Colombia). STANDINGS: Costa Rica, 2nd in Hexagonal (2 wins, 1 loss, 1 tie, 7 goals for, 4 goals against, 7 points); Jamaica, 4th in the Hexagonal on goal difference (1 win, 1 loss, 2 ties, 2 goals for, 5 goals against, 5 points). FIELD SWITCH: Costa Rica and Jamaica were originally scheduled to play in San Jose’s Saprissa Stadium, but Tico coach Alexandre Guimaraes moved the game to Alajuela’s Alejandro Morera Stadium. The Morera Stadium field is wider than Saprissa’s field, and Guimaraes believes Jamaica can’t handle his team’s speed. BOYZ MOVES: With Ricardo Gardner suspended (accumulation of yellow cards), Miami Fusion defender Tyrone Marshall is expected to switch to left back and Jamie Lawrence will take over at right back. Deon Burton, suspended for the U.S. game, will probably replace Wolde Harris up front. Veteran Fitzroy Simpson could make his first appearance in the Hexagonal, reinforcing the Boyz’ midfield. HISTORY: The only time Jamaica has beaten Costa Rica in six World Cup qualifiers was in 1997 when the Boyz beat the Ticos, 1-0, in Kingston on Burton’s goal. The win was the third in a row by Jamaica en route to its first trip to the World Cup. QUOTABLE: “To defeat Mexico was a good step, but nothing is definite.” (Guimaraes)
