Celso Borges' goal in the 64th minute gave Costa Rica a 1-0 win over Jamaica in the CONCACAF Gold Cup on Tuesday. Borges slid to get under a low cross from second-half substitute Pablo Herrera, knocking the ball beneath the arm of goalkeeper Donovan Ricketts. Following its first win, Costa Rica will face Canada on Friday in Group A. Jamaica was winless and will have to get past El Salvador on Friday to have any hope of advancing out of the group stage. Walter Centeno barely missed putting Costa Rica ahead in the 20th when his header beat Ricketts but deflected off the crossbar. A spinning shot from Jamaica forward Omar Cummings left goalkeeper Ricardo Gonzalez flat-footed as the ball dipped rapidly behind his head but bounced off the upper-left corner of the goal and out of play in the 29th. Jamaica played a man down after mid-fielder Rudolph Austin was shown a red card by referee Jair Marrufo for his tackle against Borges in the 35th. But the Reggae Boyz held their own with 10 men, pressing the attack at the start of the second half before surrendering the decisive goal to Borges. Cummings squandered an opening against Gonzalez in the 51st, hesitating on his shot and giving three Ticos defenders time to snuff out the opportunity. Eleven minutes later, Jamaica midfielder Demar Phillips found space inside the penalty area and sent a shot skimming just over the crossbar and off the top netting. Canada edges El Salvador Ali Gerba scored for the second straight game and Canada strengthened its hold on Group A of the CONCACAF Gold Cup with a 1-0 win over El Salvador on Tuesday. Defender Manuel Salazar headed the ball out of the penalty area, but it fell to the feet of Canada's Patrice Bernier, who fired toward goal, leaving Gerba to deflect the ball past goalkeeper Miguel Montes in the 32nd minute.
