CALDWELL - The Lakeside Knights had the game right where they wanted early in the third quarter.

The Knights trailed Dietrich 41-35, but the Blue Devils' top player, 6-foot-4 senior forward Trey Dill, picked up his third and fourth fouls within seconds of each other, and went to the bench just 1 minute, 25 seconds into the third quarter.

But Lakeside couldn't take advantage.

Dietrich blew the game open with a combination of a four-corners offense and a relentless fast break and raced past the Knights, 87-58, in the first round of the state 1A Division II boys basketball tournament Thursday afternoon at Caldwell High.

"We had 'em in foul trouble, and then we let that slip off our minds," said Lakeside senior guard Hunter Kolar, who scored 24 points. "And we started getting out-rebounded and out-hustled, started fouling, and playing lazy defense."

Lakeside (13-9), at state for the first time since 2006, plays Council (19-5) today at 5:15 p.m. PST in a loser-out game. Dietrich (21-3), which broke Kendrick's classification record of points in a game of 78 in 2013, plays Rockland (20-5) in a semifinal game this afternoon. Rockland defeated Council 41-29.

Lakeside played right with Dietrich throughout the first half.

But after Dill picked up his fourth foul, Dietrich went to the four corners - not to stall, but to spread the court and draw out the Knights' defense. That accomplished, the Blue Devils drove by the Lakeside defenders for layups, or drives and dishes for layups.

"We had it where we wanted - attack the big kids, get them in foul trouble," Kolar said. "We got their best player out of the game, and we just slipped away from attacking the basket, started resorting to outside shots."

"That was our missed opportunity," Lakeside coach Stacey Sonder said. "We didn't score when the chances were there."

Sophomore guard Takoda Abrahamson scored 10 of his 14 points in the first half for Lakeside. Senior forward Jordan Nilson scored all 11 of his points in the first half.

Austin Fenstermaker, a 6-3 senior center, scored 23 points and hauled in 25 rebounds for Dietrich, which outrebounded Lakeside 46-26. Dill, who banked in a half-court shot at the end of the first quarter, finished with 19 points.

"We got outrebounded," Sonder said. "You can't win a game with just (26) rebounds. They just out-hustled us. If we would have battled on the boards we would have been fine."

Point guard Garrett Astle scored 13 points for Dietrich, which shot 62.3 percent (33 of 53) from the field. Lakeside shot 53.8 percent (14 of 26) from the field in the first half, but just 24.2 percent (8 of 33) in the second half.

"They look like they got tired at the end, actually in the third quarter," 13th-year Dietrich coach Wayne Dill said. "Lakeside's a good basketball team. They shoot the ball really well. We had guys with hands in their faces, and they shot the ball really well."
