WAIPAHU — Kapa'a is making the most of its second chances.

Kalia Mayer scored twice in the first half off of rebounds and Kapa'a held off a late rally to upset defending champion and fourth-seeded Kamehameha-Hawai'i, 3-2, in yesterday's quarterfinals of the JN Automotive Group/Hawai'i High School Athletic Association Girls Division II Soccer State Championships at Waipi'o Peninsula Soccer Complex.

"We just wanted to get the ball out so we didn't have to go to shootouts," said Kapa'a defender Larissa Crain, who helped fend off Kamehameha-Hawai'i's late rally. "Last year we didn't have a good states. This year we're trying to go far."

Kapa'a (6-3-1), which beat Mid-Pacific in Wednesday's first round, plays No. 1 Kailua (11-0-0) in this afternoon's semifinals. No. 2 Kaua'i (8-0-1) plays No. 3 Pac-Five (5-6-2) in the other semifinal. Both matches start at 3 p.m.

Mayer scored in the 19th minute after a shot was poked away by the Kamehameha goalkeeper, but went directly to Mayer, who put it away.

"I'm really stoked because the first goal shot, I didn't think it would go in," Mayer said. "We had to keep pushing."

Mayer scored again 10 minutes later to make it 2-0 after the ball bounced around in the 18-yard box among several players and Mayer called for it.

"My girls kept knocking on the door," Kapa'a coach Colby Ayonon. "We had six shots in the first 15 minutes. One was bound to go in."

Kaimalie Zirker scored in the 54th minute to make it 3-0.

Kamehameha-Hawai'i (8-3-2), which pushed the tempo from the beginning of the second half, scored in the 65th minute after Jessica Marote's shot went over Kapa'a backup goalkeeper Kichiri Rodrick. Rodrick replaced 6-foot Kyah Schneider in the 58th minute.

Marote scored again in the 78th minute after her initial shot was deflected out by Rodrick and into a group of players.

"We didn't start playing until the second half," Kamehameha-Hawai'i coach Charles Heaukulani said. "We knew Kapa'a was a serious team."
