Jamaica beat Panama to reach third straight Gold Cup semi

Mattocks, who had come on as a substitute just two minutes earlier, struck from the spot with less than 15 minutes left.

"We lacked finishing," said Panama coach Julio Dely Valdes. "Jamaica almost had no chances."

Jamaica, runners up in 2015 and 2017, will play the United States in next Wednesday's semi-final after the defending champions beat Curacao 1-0.

Mexico will play Haiti in the other semi-final a day earlier.

The final will be held in Chicago on July 7.
