Rosalia wasn't happy about that celebration.
"It made me want to beat them up," he said.
With two outs, Ademar Rifaela singled and Vincent Anthonia walked on four pitches, setting up 13-year-old Rosalia's at-bat. Rosalia was down to his last strike with Curacao on the brink of elimination when he hit a 1-2 fastball over the fence.

He said it was his first game-winning homer.
