A second-half headed goal by 28-year-old Jamaican Je-Vaughn Watson made certain that Houston Dynamo repelled FAS, 3-1, on Wednesday night at Estadio Cuscatlán, San Salvador in Group III of the CONCACAF Champions League.
All three goals from Houston were headers, with the US Major League Soccer team recording their first away victory in eight Champions League matches to join Olimpia of Honduras at the top of the group with three points.
Unmarked Brian Ching headed down a Colin Clark cross in the box in the 12th minute which beat goalkeeper Luis Contreras. Seven minutes later, Cam Weaver nodded home a Kofi Sarkodie cross from eight metres for Houston for their second goal.
Watson gave Dynamo a commanding lead on the hour when he guided in Nathan Sturgis' corner kick.
The El Salvador team finally responded in the 64th when second-half substitute Jonathan Águilla netted, flicking a close-range shot past Tyler Deric.
Houston enjoyed only 42 per cent possession, with five corners, two shots wide, 11 fouls, and twice offside against FAS.
A Sporting Central player, Watson is in his second season with Houston Dynamo, so far playing 16 matches and logging 927 minutes in the MLS and 90 in the Champions League.
He joins Nicholas Addlery of Puerto Rico Islanders and Ryan Johnson of Toronto FC as Jamaicans scoring in the Champions League, each with one goal.
Born in St Catherine, Watson has 21 caps and one goal for Jamaica. He scored in the Reggae Boyz 3-0 win against Cuba on February 24 at Catherine Hall in Montego Bay.
Dynamo next take on Olimpia at Estadio Tiburcio Carías Andino in Tegucigalpa next Thursday at 9:00 pm (Jamaican time).
