Like any restless coach headed into a state basketball tournament on opening day -- and with a 10:30 a.m. tipoff for added uncertainly -- Manuel Rangel had his concerns.

How would his White Swan boys react? With no recent state experience to draw from and a dangerous opponent on the floor, Rangel had good reason to be anxious about the opening minutes of the Class 1A state tournament in the SunDome on Wednesday.

But those pacesetting minutes were all White Swan as the well-composed Cougars flew out to a 14-0 lead and rolled to a 59-45 victory over Lakeside in the program’s first state appearance in three years.

Senior guard Adrian Komaromy drained two 3-pointers from the top of the key during the breakaway start and helped orchestrate a continuously effective fastbreak that never allowed the Eagles to make a serious comeback.

“We were a little nervous but everybody is before the first game,” Komaromy said. “We had a great start and we just took it from there. We played games in here before in the (SunDome) Shootout so we’re used it. We like to push the ball and we like the longer floor.”

Not your typical “bigs,” White Swan’s senior front line of Aaron Castilleja and Brady Carl finished many of the breaks. Castilleja made 7 of 9 shots for a game-high 14 points and Carl had eight points and seven rebounds.

“Our big guys run better than anybody else’s,” said Komaromy, who finished with 12 points. “They like it as much as the guards do.”

“Either way is fine for me -- on the break or down low,” Castilleja said. “I thought we did both real well today.”

Indeed there was little the Cougars did wrong and the big blitz at the start was responsible for it. Down by so much so early, Lakeside could never find its shooting touch, missing 16 of 17 from 3-point distance and shooting just 26.4 percent overall for the game.

When the Eagles brought more pressure in the second half, White Swan responded from the foul line. Guards Travis Van Pelt, Drew Blodgett and Komaromy combined to hit 10 of 10 free throws in the final four minutes.

“I told the kids those Shootout games will help us. It’s the same environment, the same court,” Rangel said. “Obviously I had concerns, but we have boys who practice hard and enjoy playing together. I hoped they would come ready to play and they did.”

Van Pelt picked up six assists and made all six of his free throws, and Guy Sanchey, the lone nonsenior starter, had three steals.

Lakeside came in having won 15 of 17 games after an 0-8 start, but the Eagles managed just 23 points through three quarters. After 14 tries, Lakeside hit its first 3-pointer with 2:54 left in the game.

“I always see things I think could be better, but the defense was solid,” Rangel said. “The boys had the intensity and effort today.”

In Thursday’s first quarterfinal at 4 p.m., White Swan (20-5) will face seventh-ranked Vashon (21-4), which held on to beat Toledo 55-54 in Wednesday’s 9 a.m. opener.
