SOUTH WILLIAMSPORT— Now that was more like it, manager Rick Tibbett said after watching his Chula Vista, Calif., team put on a home run show at the Little League World Series on Sunday.

Jake Espinoza, Micah Pietila-Wiggs, Michael Gaines and Grant Holman all homered in a mercy rule-shortened 15-3 victory over Newark, Del.

Holman capped an eight-run fourth inning, by hitting the first pitch he faced over the fence in center for a game-ending grand slam.

It was a significant reversal after the Californians needed an extra inning to pull out a 3-0 victory over Grosse Pointe, Mich., in their series opener.

“That’s what we do best,” Tibbett said, of a team that averaged 11 runs in six games to clinch the West championship.

And he certainly wasn’t concerned after his team trailed Newark 2-0 after the top of the first inning.

“Yeah, two runs is not going to keep us down. It just doesn’t,” Tibbett said. “Normally, we score 8-10 runs a game. It didn’t bother us one bit.”

Chula Vista (2-0) advanced to play Westport, Conn. (2-0), on Wednesday. And they weren’t the only ones that made quick work of their opponents. Mexico improved to 2-0 with a 13-0 four-inning win over Aguadulce, Panama, (1-1).

“They hit everything we threw at them — fastballs, curveballs and change-ups,” Panama manager Luis Gonzalez said

The outcome was much tighter for the two other teams who remained undefeated.

Westport built a 9-2 lead through four innings, and hung on for a 9-7 win over Sammamish, Wash.

Tokyo, Japan, gave up two unearned runs in the final inning, before securing a 3-2 win over Taoyuan, Taiwan.
