SAN JUAN, Puerto Rico — Yadier Molina's go-ahead double keyed a three-run rally in the eighth inning, and Puerto Rico beat a pesky Netherlands team 3-1 on Monday night to advance to the second round of the World Baseball Classic.

The Netherlands pulled off a major upset in its tournament opener Saturday, beating the Dominican Republic 3-2. The pitching staff, with coach Bert Blyleven in the dugout, also was impressive against favored Puerto Rico, protecting a 1-0 lead until the eighth.

Big league sluggers Carlos Delgado and Alex Rios opened the inning with walks. After Ivan Rodriguez struck out, Mike Aviles walked to load the bases and Molina followed with a two-run double to left off Leon Boyd that put Puerto Rico in front before a sold-out home crowd of 19,479 at Hiram Bithorn Stadium.

Alex Cora flied out, but Jesus Feliciano's RBI single made it 3-1. On the play, Molina was thrown out at the plate.

J.C. Romero and Fernando Cabrera combined for a perfect ninth, sending Puerto Rico to Miami for second-round action beginning Saturday.

The Netherlands will face the Dominican Republic again in an elimination game Tuesday night. The winner of that game will play Puerto Rico on Wednesday for first place in Group D.

Pittsburgh Pirates right-hander Ian Snell started for Puerto Rico, allowing one run and three hits in four innings. He struck out five and walked one.

Pedro Feliciano provided 1 1-3 innings of scoreless relief. Romero also worked 1 1-3 innings for the win.

Netherlands starter Rick VandenHurk pitched three-hit ball for 3 1-3 innings.
