SOUTH WILLIAMSPORT — Jorge Romero put Mexico in front with one big swing, and then he finished the job from the mound.

Romero hit a two-run homer in the top of the seventh, and Tijuana, Mexico, rallied past Aguadulce, Panama, 4-2 on Thursday night to earn a berth in the international championship game at the Little League World Series.

Jorge Rodriguez reached on a bunt single before Romero connected against Edgardo Rosales, sending a drive over the wall in center.

“I was just thinking my job was to get a hit and get on base so I could score a run,” Romero said.

The rain-delayed victory set up a rematch between Mexico and Tokyo, Japan on Saturday. The second game on Thursday’s slate between Westport, Conn., and Sammamish, Wash., for a berth in the U.S. final against Chula Vista, Calif., was moved to Friday.

Mexico went ahead 2-1 in the fifth. Brandon Montes led off with a long drive to left-center for his fourth World Series homer, and Alex Artalejo added an RBI single.
