Denison-Schleswig ran up a 23-10 lead after one quarter and wouldn't look back as they rode an impressive effort from Derek Hall, who poured in 28 points on 9-of-14 shooting. He added nine rebounds and two steals. Zac Johnson added nine points and 14 rebounds for the Monarchs.
"It's very frustrating," said SL coach Bob Grant. "The guys are frustrated. We'll have to break down the tape, but we were not very good."
The Tornadoes would close within single digits twice in the second half but get no closer than nine.
It was a strong shooting night for D-S, who connected on 23-of-53 from the floor and 16-of-26 at the line. They improve to 1-1 after falling to St. Mary's in their season opener.
Aaron Krier was one of the few bright spots for the Tornadoes as he turned in 17. It was another quiet night for SL big man Ethan Kenkel as he netted just two points. He did, however, post double-digit rebounds.
"We just couldn't get it to him (Kenkel)," said Grant. "That was our goal coming in, get it to him on the low block and let him do his work."
The Tornadoes fall to 0-2 on the season, and things won get any easier next week as they travel to Western Christian (0-0) Tuesday before hosting Spirit Lake (1-0) Friday.
"I expect those two to be at the top of the conference," said Grant. "I think we can be the aggressors, but we weren't the aggressors tonight (Thursday). Hopefully we'll be able to do better against Western."
