Another back-and-forth matchup between two new league rivals with a third place trophy on the line ultimately came down to one simple factor.

Zillah had Dekker Van De Graaf. Royal didn’t.

The SCAC player of the year took over after halftime, willing the No. 4 seed Leopards to a 75-70 overtime win over a team they lost to in two of their first three meetings this season. Van De Graaf’s eye-popping stat line of 36 points with 6 of 7 shooting from 3-point range, 12 rebounds and two blocks only told part of the story for a player coach Mario Mengarelli said “literally does everything” for Zillah.

“He’s a special player and he’s the greatest Zillah scorer of all time,” Mengarelli said. “Probably the greatest Zillah player of all time and it showed today.”

That’s high praise at one of the Valley’s top programs and it’s hard to argue after Van De Graaf reached 1,483 points Saturday, surpassing Trey Delp’s school record with a full season left to play. Van De Graaf once again showed he’s at his best in the most important moments a year after he scored the last nine points and the game-winning basket of the Leopards’ 47-45 state championship win over Annie Wright.

This game didn’t quite have those same high stakes, but it still meant more than just a better trophy to the Leopards after they gave up a 27-point lead and lost 73-59 to Royal in the district title game at Wenatchee two weeks ago. Van De Graaf and Castilleja both said they drew significant motivation from that disappointment, and Mengarelli said it’s great to have another rival thanks to the elimination of the SCAC’s old East and West divisions.

“They’re good and I think they’re going to be good for a while,” Mengarelli said of the school traditionally known as 1A’s football powerhouse. “We had Toppenish for a while and now they went 2A, they’re not as relevant, but yeah, it’s good for us.”

The Knights’ depth showed as Dax Jenks came off the bench and recorded a double-double of 20 points and 10 rebounds, including 10 points in the second quarter to help his team take a 31-27 halftime lead. Zillah relied on defense and free throws to weather a field goal drought of more than four and a half minutes to end the first quarter and Memphis Jones scored 11 of his 15 points before the Leopards headed to the locker room.

When they returned, Van De Graaf found his range with three third-quarter 3-pointers, capped off by a stepback jumper just before the buzzer to tie the game at 50. Royal tried to counter by pressing up to guard his shot, so he attacked and rose above defenders to finish at the rim.

“(Assistant coach Erick Delp) told me, ‘you’re a junior, you need to take over now, time’s ticking,’” Van De Graaf said. “So I got in my bag. He told me to put the backpack on and I did.”

Five more points from Van De Graaf to start the fourth quarter gave Zillah a small cushion, and Mengarelli said the Leopards showed better poise playing with a lead than in the last two days, when they saw a 20-point lead evaporate before beating Seton Catholic and then watched a four-point halftime advantage turn into a 55-37 loss to No. 1 Annie Wright. Van De Graaf praised point guard Xavier Castilleja’s ability to take care of the ball, and the 5-foot-9 sophomore also proved effective on the drive to score 14 points.

He emphasized the importance of avoiding turnovers and getting the Leopards into their offensive sets rather than worrying too much about running out the clock. Royal still eventually tied the game thanks to four straight points by Grant Wardenaar to end regulation, but Castilleja knew to turn to Van De Graaf in overtime.

“we’ve been playing since we’ve been little kids, third grade,” Castilleja said. “So we’ve always had a connection.”

Van De Graaf knocked down a pair of field goals, including a 3-pointer, before making all four of his free throws in the last 20 seconds to seal Zillah’s third straight top four finish. Mengarelli said Van De Graaf’s visit to the nearest trash can while the clock ran out came not from sickness, but from overwhelming exhaustion and how hard he played for nearly 34 minutes.

He returned as the lone starter this season and said that unfamiliarity contributed to an 0-2 start against a tough nonleague schedule before the Leopards rebounded to win 19 of 20 games and posted a 21-5 record. Only one starter will graduate, so Castilleja and Van De Graaf both expect to return with high expectations.

“As we got on, we started figuring out each other’s strengths and learned how to play off each other,” said Van De Graaf, who plans to go to Seattle Sunday for a tryout with the Nike EYBL’s Seattle Rotary AAU team. “We’re hungry and we’re going to be back for what’s ours.”
