MCCULLY — About 24 hours after its devastating loss to Kamehameha, Saint Louis bounced back with a 4-0 win against Punahou in an elimination game of the Interscholastic League of Honolulu Division I second round at Ala Wai Community Park.

With the victory, the No. 2 Crusaders (13-5) clinched the league's second state tournament berth. They will face No. 1 Kamehameha, 10 a.m. Saturday.

The regular-season champiion Warriors (14-3), who have clinched the league's other berth, can take the league's seeded berth with a win. The Crusaders, second in the regular season and at worst second in the double-elimination round, needs to beat Kamehameha three consecutive times to earn the seeded berth.

"We're going to play to win, but obviously with a lot less pressure," Saint Louis coach George Gusman said. "We'll play and do our best and we'll see what happens."

Punahou (12-7) is done for the season.

"Tip your cap to Saint Louis," Punahou coach Keenan Sue said. "They've played great all year. (The ILH has) two really great representatives in the state tournament, so I'm really happy for those guys."

Senior right-hander Dylan Lum delivered a three-hitter fand senior right fielder Matthew Wong drove in two runs to pace the Crusaders. Lum (3-1) walked none and struck out a season-high six in his only outing against the Buffanblu this season.

"It's pressure," Lum said of his team's situation entering the game. "But it's just believing in my team and those fans behind me. I can do it, so today i just came out and I had to get this game and bring it home to Kalaepohaku."

Lum threw 92 pitches, 57 for strikes (62 percent).

"Dylan was unbelievable today," Gusman said. "He had command of his curveball, fastball, hitting his spots."

Fourteen of the 25 batters Lum faced saw or swung at first-pitch strikes.

"He threw a lot of first-pitch strikes and our guys were working behind in the count almost every at-bat," Sue said. "When you're a pitch and you command early strikes, you're going to win the ball game.

"He's a great pitcher. We haven't seen him all year and he pitched like a veteran today."

Saint Louis cashed in on two of three Punahou errors accounting for three unearned runs off Buffanblu starting pitcher Kyle Uemura (5-3), who was charged with one earned run and allowed and eight hits in 4 1/3 innings. 

"They hit when they needed to and we made some key errors and (allowed) a couple of key walks," Sue said. "We didn't do what we've done all year, which is play good defense."

The Crusaders jumped to a 3-0 lead in the top of the third inning. Makana Ontai led off with a high-chopped single to short and took second on Keith Torres' single to center. Dylan Pagente bunted the runners over, but Uemura's throw sailed over first base, allowing both runners to score. Pagente made it all the way to third. An out later, he scored on Wong's single to right before Uemura retired the next two batters.

An error in the fifth accounted for Saint Louis' last run. DJ Stephen reached on a two-base fielding error by second baseman Andrew Matsueda and scored on Wong's ensuing double to left to chase Uemura. Kahi Bisho took over and Charlie Lopez reached on a fielder's choice to the pitcher that led to Wong getting caught in a rundown between second and third. Lopez was then caught stealing second to end the inning.

Wong said both of his RBI hits were off of changeups, which he saw in all three of his at-bats against Uemura.

The Buffanblu threatened in the fifth when Noah Loughlin singled and went to third on Matthew Nakamoto's double to right by right fielder Wong. But Lum fought back by striking out pinch hitters Brent Shimoda and Ryan Nishi to douse the threat.

"Matt thought he should've had that in right field," Gusman said. "I expect them from them, but for (Lum) to get out of that inning with no runs, that's the kind of day he had."

Lum said the struck out both batters with his slider, which he used the majority of the game.

The Crusaders didn't have time to dwell on what might have been after they squandered 4-1 lead in the bottom of the seventh to Kamehameha in a 5-4 heart-breaking loss.

"Yesterday was tough, being up three runs in the bottom of the seventh," Wong said. "But the day before that, we had a word of the day: no short-term memory. So good for us we talked about it last night and discussed that we're just going to forget about that and come back today with fresh minds and play our hearts out."
