TECUMSEH — Turnovers and troublesome defense was the Cyclones’ downfall Friday. Shawnee Heights beat the visiting Ottawa High School boys basketball team 73-59 in Tecumseh.

Both teams came out firing in the first quarter. A basket by Cade Gollier, OHS junior, with three seconds left gave the Cyclones a 21-20 lead after eight minutes.

The wheels started to fall off in the second quarter. Turnovers led to easy baskets for the Thunderbirds.

An 18-0 run gave Heights a big lead and Ottawa went into the locker rooms at the break in a 44-30 hole.

The team battled back in the third, coming within six points (50-44) off a basket by Kobe Johnson, junior, with 39 seconds left.

Heights, however, distanced themselves again by beginning the fourth quarter with a flurry of threes.

The Thunderbirds hit five three-point baskets within the first two-and-half minutes of the period.

Three of those shots were sunk by senior Isaiah Bonjour, who led all scorers with 25 points.

“We were bad defensively, I mean horrible defensively,” Cliff McCullough, OHS head boys basketball coach, said. “When you have guys shooting that loose from behind the arc and we just have no chance of even contesting the shot...that is just terrible defense. Until we fix that, teams are going to tee off on us.”

Kobe Johnson led Ottawa with 19 points. Harvey Davis Jr. scored 10 for the Thunderbirds.

Ottawa (1-2) plays 7:30 p.m. Tuesday at Topeka West.

Shawnee Heights (73) — Bonjour 25, Davis Jr. 10, Donohoe 9, Barksdale 9, Brown 8, Watson 7, Johnson 3, Walker-Ladish 2.
