SAN JUAN, Puerto Rico (AP) — Carlos Beltran's RBI double keyed a three-run first inning that was enough for Puerto Rico to beat Spain 3-0 on Friday at the World Baseball Classic.

In the tournament opener for both teams, Angel Pagan got Puerto Rico started with a leadoff single off Sergio Perez. One out later, Alex Rios was hit by a pitch and Beltran drove in Pagan with a double to right.

After an error and a sacrifice fly, consecutive walks forced in another run.

Puerto Rico starter Giancarlo Alvarado struck out four in four scoreless innings. Hiram Burgos followed with 4 2-3 innings and Xavier Cedeno threw a called third strike with a runner on to end it.
