Aubree Kim gives new meaning to being un-hittable.

The sophomore right-hander pitched a one-hitter and got backing unexpected power sources and No. 3 Mililani over-powered No. 2 Mid-Pacific Institute, 9-1, Thursday night in a semifinal of the DataHouse Division state softball tournament at Rainbow Wahine Softball Stadium.

The Trojans (14-3) will meet a very familiar foe in No. 6 Campbell (15-4) in the first all-O'ahu Interscholastic Association Red West championship since Pearl City beat Mililani, 2-1, in the 2006. Mililani is looking for its first title since 2009 and third overall. Campbell is seeking its first since 2010. Mililani and Campbell shared the Red West title with 9-3 records (along with Wai'anae), but the Trojans were seeded first because of head-to-head tiebreakers. The Trojans split their home-and-home regular-season series, but beat the Sabers for the OIA Red championship.

Kim (13-1), who has allowed 44 walks to 36 hits in 74 innings this season, was tough to figure for the power-ladened Owls, who could not square-up on any of her pitches as evident by the one single they got from Jenna Kumabe. They drew a staggering 11 walks, showing discipline at times, yet they struck out nine times, displaying confusion in their approach.

"We were pretty disciplined, actually," MPI coach Alan Inaba said. "We made her throw a lot of pitches. We made good counts. Something about when it got to 3-2, we kind of changed our approach. We must've had six strikeouts or more on (pitches) out of the zone."

Kim threw an astounding 178 pitches. She admitted trying to be extra careful against the Owls' feared lineup with the likes of Nicole Lopez (six homers) and Sarah Onishi (five homers).

"I was trying not to keep it juicy over the plate," Kim said. "Seemed to be that every time I threw a nice one on the corner, or a little low or high strike, I wouldn't get the call. I was trying to keep it off the plate, so maybe that's why I had a lot of walks, but I don't know."

When the Owls managed to make contact, the Trojans' defense stepped up. Catcher Markie Okamoto made a nice stab at a foul pop up of Samantha Sakihara in the second inning. Left fielder Kylyn Sasaki made a difficult grab on a drive off the bat of Lopez in the fifth.

"I can't thank my teammates enough for having my back the whole way," Kim said. "Even though the bases were always loaded, I'm so thankful and happy for my teammates."

Three times the Owls stranded the bases loaded. Kim got a strikeout from a first-inning jam, a fly out to center in the second and a line out to right fielder Keri Togami. Yet, between her sixth and seventh walks of the game, she had retired 12 Owls' in a row.

"Give her credit," Inaba said. "She got the big outs when she needed to."

The Trojans flashed a part of their game not seen most of the season: power. Four of their nine hits went for extra bases, including three in a row.

Down 1-0, the Trojans got back-to-back doubles from Justine Fabella and Okamoto followed by Sasaki's two-run homer off MPI starter Kaili-Ann Akimseu. Mililani then put the exclamation point on the night when 4-foot-11 shortstop Jade Yadao-Valdez - a slap-hitting, drag-bunting speedster who lives off 30-foot singles, lined a solo home run to right-center, her first out-of-the-park hit batting from the left side, she said.

"I usually slap, but I wanted to try something different," Yadao-Valdez said. "I stood there, saw the down-the-middle pitch and just swung. I was so shocked."

She was not the only one.

"They're a small-ball team and they came out with their bats today," Inaba said.

The Owls' only run came in the top of the first. Taylor Ann Oda walked with one out and went to second when Lopez walked. Oda stole third on a 3-0 pitch that was called a strike. Lopez then stole second on the next pitch, drawing an errant throw from catcher Okamoto, allowing Oda to score.

After the Trojans' three-run second, they sent 10 batters to the plate in a five-run fifth.

Notes: It was determined after Thursday's game that Mililani will be the home team for Friday's championship. The determination is made by coin toss, as it was throughout the tournament. That bodes well for the Trojans, who won two of their three meetings with Campbell as the designated home team. The Sabers' only win was at their 'Ewa Beach campus, while both the Mililani wins were at Central O'ahu Regional Park (once in regular season and the other in the OIA championship).
