Northridge, which has hit 24 home runs in seven postseason contests, scored seven runs in the bottom of the fifth inning to take a 13-4 lead. Gangi, who guided Crescenta Valley to the District 16 title, probably had seen enough of Northridge's stacked lineup.
"It all came down to having top-tier pitching," said Gangi, whose team advanced to the title game with an 8-5 win against Quartz Hill on Monday. "We had Will Lombardo and Andres Kim and, if we had one more ace, it might have made a difference.
"We had a great run to get here, but we just ran out of pitching."
Crescenta Valley, which fell to Northridge, 5-1, in a winner's-bracket game Sunday, pulled to within 6-4 in the fifth on a solo home run to center field by Greg Stupakis. However, Crescenta Valley couldn't get any closer.
"The teams are a lot tougher here then in District 16," said Stupakis, who finished with a pair of hits. "We came out and battled and we had a chance until the end.
"It's real great to just get here. We had a lot of practices along the way and we battled [with Northridge]."
Northridge took a 2-0 lead in the first on solo home runs by Christian Goretti and Angelo Diazzesati before Crescenta Valley sliced the lead to 2-1 in the second on a run-scoring single by Jonathan Tyler.
After Northridge extended its lead to 4-1, Crescenta Valley pulled to within 4-3 on a two-run double by Travis Westoff.
Northridge got home runs from Derek Kraemer, Brandon Lewis, Anthony Pineada and a grand slam from Rece Reagan.
"They have a good hitting team," Gangi said. "I'm most proud that we continued to fight to the finish."
