WAILUKU >> After all the adversity of eking out a state-tournament berth out of the treacherous land of ILH baseball, Punahou’s state-title aspirations are no more.

It took a sophomore, Nicholas Sampson, and a freshman, Ayzek Silva, pitching in the spotlight for Campbell. Sampson started on the mound, but provided the biggest play at the end, scoring the go-ahead run on a throwing error in the top of the seventh inning for a 3-2 upset win over Punahou on Wednesday night in the opening round of the Wally Yonamine Foundation/HHSAA Baseball State Championships at Iron Maehara Stadium.

Campbell will meet third-seeded Kailua today in a 10:45 a.m. quarterfinal matchup.

ILH runner-up Punahou (12-10) entered the tourney ranked No. 4 in the Star-Advertiser Baseball Top 10.

Unranked Campbell, the defending state champion, went through a major facelift with the graduation of several key players. There are just four seniors on this year’s roster, but at this point, their underclassmen are playing like veterans. Sampson, a 5-foot-11 right-hander, went 4 2/3 innings. He was almost surprised to be interviewed after Campbell (11-6), the OIA’s fifth-place team, pulled the biggest surprise of the opening round.

“I just kept the same mentality I have for all games,” he said. “Trust my pitches and trust my defense.”

Sampson scored the go-ahead run on a stunningly crazy play in that seventh inning. He reached base on a fielder’s choice grounder after Todd Takahama Jr. had opened the frame with a single. Punahou starting pitcher Noah Goss then walked Kainoa Ganancial, the No. 9 hitter in the lineup; Ganancial went 2-for-2 with the walk.

After reliever Riley Guieb fanned Shane Shimizu for the second out, he threw an 0-1 pitch to pinch hitter Dylan Ramon in the dirt. Catcher Logan Williams hustled after the wild pitch and fired to third base as Sampson attempted to advance from second.

“I saw the ball pass the left side of my body as I was diving in,” Sampson said. “Coach Rory (Pico) was yelling, “Go! Go! Go!’ so I got up as fast as I could and took off.”

Sampson scored at home plate as the throw in from the outfield was slightly off line, giving Campbell a 3-2 lead.

Guieb retired Ramon and the rest was a battle between Punahou and Silva. The freshman entered the game during the fifth inning. He got out of a slight jam in the sixth, stranding two runners. In the seventh, he fanned Goss on a high fastball and got Easton Takamoto to pop out. Noah Loughlin singled to center, but Silva induced Andrew Matsueda into a foul pop out to end the game.

“I had to go out there and shut the door. I was pumped,” said Silva, who located his fastball and curve well, but couldn’t get the change-up going. “Our coaches said to go out there and throw strikes.”

Campbell broke a scoring drought in the top of the fourth inning. Jordan Macias, who had a sterling performance at shortstop, led off with an infield single, and Roy Clemons’ sacrifice bunt turned into a throw by the pitcher, Goss, to second base. The force-out attempt was off and Campbell had two runners on base.

With two outs, Takahama singled to center, bringing Macias and pinch runner Kai Kaaiakamanu home for a 2-0 lead.

Punahou tied the game in the bottom of the fifth. Asa Kurasaki led off with a double, advanced to third base on a wild pitch and scored on a sacrifice fly by Cole Cabrera. Goss followed with a single and came home on a double by Takamoto to make it 2-all.

Colby Hirano singled to left with two outs in the bottom of the 10th inning off Jyrah Lalim, scoring Trestan Nakamura from third base with the game’s only run, advancing the Chargers (15-1) to the quarterfinal round.

It was an epic battle between the OIA’s third-place team and the MIL’s runner-up. Chargers starting pitcher Trenton Darley went eight innings, allowing just five hits with five strikeouts and one walk issued. Trestan Nakamura took over in the ninth and earned the win.

Mililani 7, Kalani 1

Justin Ogasawara hurled a five-hitter as Mililani, the OIA’s sixth-place team, stunned Kalani, the league’s runner-up.

Ogasawara struck out three, including the final two batters, and did not walk a batter. His arsenal of curveballs, backdoor fastballs and change-ups stifled the Falcons, who reached the OIA title game recently.

“This is big for us. We know that we’re good. We had to do what we do at practice,” said Ogasawara, who outdueled Kalani ace Connor Zalewski.

Waipahu 7, Hilo 5

Khaine Viliamu sparked a seventh-inning uprising with a ground-rule double as the Marauders (6-11) pulled away from the Vikings.

“I feel proud,” Viliamu said of a program that was in Division II a few seasons ago.

With the score at 5-all, Viliamu led off the top of the seventh with a blast to left center that bounced over the fence near the 370-foot marker.

Moments later, Michael Price, who had ripped a grand slam in the second inning, laid down a sacrifice bunt.

Kobie Russell and Cole Phillips. Josiah Factora, Brett Komatsu (5) and Joshua Breitbarth.
