HAWAII KAI — The West's best will square off in East Honolulu Saturday night with a league title at stake. 

The championship game of the Oahu Interscholastic Association Division I girls soccer tournament will feature No. 4 Mililani and No. 6 Waipahu, the first and second seeds, respectively, out of the Western Division. 

The Trojans (12-0) and Marauders (11-1) punched their tickets to the final with victories in Thursday's semifinal round at Kaiser Stadium. 

Mililani blanked No. 9 Campbell (9-3-1) , 2-0, in the first semifinal, while Waipahu won the nightcap in thrilling fashion over No. 10 Kaiser (9-1-1) by a score of 1-0 in double overtime. 

The Marauders scored the golden goal in the 94th minute, when Erin Kumasaka headed in a corner kick from fellow senior and four-year starter Deizha Lyn Jacinto. 

"I always know where Deizha places the ball, so I really try to gauge off of where she kicks it and make sure I'm in the right spot to head the ball in the goal," Kumasaka said. 

It was just Kumasaka's second goal of the season, but certainly not the first time she and Jacinto have linked up. The pair are among five four-year starters for the Marauders, who have 11 seniors in all on their roster. 

"It's really such an honor to be part of this team and really see how far we've come because we've put in so much work over the years and it really comes down to who wants it more and I really believe that we have the heart and the grit to get the job done," said Kumasaka, a key cog in the team's defense as a center-back. 

Kumasaka found herself in the middle of the six-yard box and a mass of players when Jacinto's corner kick came her way. 

"I saw Deizha kick the ball and I saw it coming right at me," she recalled. "I knew I wanted to make contact and be aggressive, but as soon as I hit the ball I think I closed my eyes and they showed me the video playback that it actually hit the back of my head and I (spun) and headed it in the goal, but we'll take it."

"It wasn't pretty — back of her head — but it's OK; She's in the right spot," Waipahu coach Brent Murakami said. 

Jacinto's corner kick was her second in as many minutes. Both were manufactured as a result of high-effort plays by another senior, Anela Leslie. 

"That was big for Anela," Murakami said. "I think she was building her confidence as the season went on and for her to not necessarily score, but to help us earn essentially the game-winning free kick, you know, was big for her."

Although Leslie wasn't officially credited with an assist on the game-winning goal, she certainly deserves one in Kumasaka's book.

"I give a lot of credit to our attackers and our wingers because they're really putting in the hard work and running hard on the balls played from our midfield and it all ties in together because we know how to play well with each other and seeing Anela's hard work, it really paid off and it felt good to get the goal in the back of the net," Kumasaka said. 

Kumasaka and the Marauders rode a roller coaster of emotions leading up to her goal. 

Four minutes into the first 10-minute, golden-goal overtime period, Jacinto had a chance from point blank after a well-placed crossing pass from teammate Keena Nakamura, but her right-footed redirection was saved by Kaiser goalkeeper Shore Carlborn. 

Then, on the other end of the spectrum, the Cougars had a golden opportunity in the closing seconds of the first overtime. Alessia Costa was on the receiving end of a near-perfect through ball that put her in position for a one-on-one look against Waipahu ‘keeper Zinn Kurose, but her shot from inside 10 yards missed wide right of the goal. 

"In the game we've got to be a little bit lucky to win tight games. I mean, we escaped. Alessia gets that opportunity again, she buries that and we lose (with) three seconds left in overtime, but we gotta use that luck, you know," Murakami said. 

Murakami used the brief two-minute intermission between overtime periods to refocus his bunch. 

"I told the girls during the break, ‘We were fortunate there and now we have to get some momentum. We cannot allow them to build on that momentum.' I think they were feeling good about what they were doing and I think we were feeling pretty junk about how we ended (the first overtime) and the girls just battled back," Murakami said. 

Waipahu's best scoring chance in regulation came with about five minutes left in the first half. Jacinto fired a free kick from about 20 yards out that ricocheted off the crossbar. The rebound came to Kumasaka, but her header attempt missed the frame of the goal by a few feet and went over the crossbar. 

Kaiser put together a few quality chances via a couple of corner kicks late in the second half, but the Marauder defense held each time.

The Cougars were shutout for the time all season. Kumasaka said cohesive play in the back alongside fellow center-back Shalyn Kahookele and outside-backs Brynn Uyeunten and Victoria Brancieri was key to containing Kaiser's speedy duo of strikers in Rory Matsumoto-Hussey and Brooke Perreira. 

"They are fast, but it's all about communication and our tactic was to keep our defense together and connected so they could not split us or play over the top," Kumasaka explained. "We've been working together for the past two years, this back line and we really know how to cover each other and we have each other's backs."

Waipahu was coming off of a hard-fought 3-2 win over Moanalua in Tuesday's quarterfinal round. Murakami's squad trailed 2-0 at halftime before it came to life after the intermission. 

"I think the win on Tuesday really kind of showed what they could do and I think they had some belief coming into (Thursday)," Murakami assessed. 

The Marauders will be seeking their first OIA championship in Division I and just their third overall. They claimed the league's D2 crown in both 2012 and 2017, the latter coming under Murakami's direction. 

"It all starts off with our coaches who put in a lot of hard work and they really train us hard. Also, as a captain, making sure that as a team we work hard at practice and it really shows in the game because we know how to play good soccer and we really know how to work together after being together for all these years since we're a (senior-heavy) class and it just feels so good to get this win and finally get to the championship after all our hard work over the years," Kumasaka said. 

Meanwhile, Mililani did all of its scoring before halftime in its two-goal victory over Campbell. 

Jaslene Cayetano scored the first goal and assisted on the second to help the Trojans return to the title game. 

Mililani lost to Campbell in penalty kicks in the OIA championship match a year ago. 

"They did remember what happened last year so it feels good," first-year Trojans coach Brendyn Agbayani said. 

Cayetano broke the seal in the 10th minute with her goal off of a free kick from about 33 yards out. After she drew the foul that led to the restart, Cayetano booted her right-footed shot toward the goal, but it was mishandled by the Campbell goalkeeper and bounced into the left side of the netting. 

"I was taking the ball down the sideline and I knew I could take the defender, but then she ended up fouling me," Cayetano said. 

Of her free kick, Cayetano added: "I was just thinking of chipping the ball into the 6, where everyone could get a head on it, but it went past the ‘keeper, so I'm glad it went in."

Cayetano assisted on the Trojans' second goal, when she placed her corner kick inside the 18-yard box and Leila Leano was there to one-time it with her right foot into the back of the net. 

"My initial thought was getting the ball up but it kind of curled into Leila, but lucky thing she was right by the penalty line, so good thing she was ready and she got it in," Cayetano said. 

It was Leano's team-leading 10th goal of the season and her third in two games. 

Mililani has yet to allow a goal all year; It has outscored opponents, 56-0. 

"That's the statistic that I'm most proud of them for, is not giving up a goal and all year we've talked about having a clean sheet and it's a testimony to their hard work," Agbayani said. 

The Trojans will be trying for their 21st league championship.

Saturday's D1 final will be preceded by the D2 title game between Waialua (5-6) and Kailua (4-6) at 5 p.m.

Kaiser and Campbell will play in the D1 third-place game Friday, 7 p.m. at Moanalua. It will follow the fifth-place final between Moanalua (9-3) and Kapolei (8-4-1) at 5:30 p.m.
