MIAMI -- Unbeaten Jamaica hardly broke their stride as they blitzed Grenada 4-1 to march into the quarter-finals of the CONCACAF Nations League on Thursday night.

With the points sealed, Fulham's Reid put the cap on a dominant Reggae Boy performance, racing on to a ball over the top to slot past goalkeeper Jason Belfon.
