Seabury Academy boys basketball coach Marcus Heckman was quite frustrated after Tuesday night’s 45-18 home loss to Marais des Cygnes Valley.

His players weren’t especially happy, either.

Just a little more than a week ago, the Seahawks scored what may have been their best victory, a 44-41, come-from-behind victory over Flint Hills — which, according to Heckman, “put his team at their season’s peak.”

Tuesday, the Seahawks plummeted to the year’s low point.

“We just didn’t execute,” Seahawk senior Steven King said.

Heckman blamed the lopsided score on a lack of energy and enthusiasm.

“It doesn’t matter what kind of X’s and O’s you run, if you do not match the other team’s competitive spirit, the game’s already over,” said Heckman, whose squad dropped to 6-13 on the season with one game remaining — Senior Night on Friday against Heritage Christian — before regionals. “That’s exactly what happened tonight to us.

“I’m very disappointed in the way we’ve played lately, especially tonight. I know that this is not the way the seniors wanted to have their last week go, but now it has provided them with quite the challenge to come out and prove themselves on Friday. I hope the kids own up to this responsibility and put in the necessary work the next few days to end the regular season on a high note.”

There was little to be happy about for Seahawk fans when it came to the game against the Trojans.

Neither team found success in the early going, as Marais des Cygnes took a 6-2 lead after the first eight minutes. But the Trojans found a way out of their funk, while Seabury remained mired in its own miscues and mistakes.

An 18-5 spurt by Marais des Cygnes over the next quarter-and-a-half all but ended things, and midway through the fourth every Seabury player saw action — though no one could change the Seahawks’ luck.

“We just didn’t come to play, and that was very, very frustrating for everyone involved,” King said. “Being a senior and in my last home game, I know that I have to step up this Friday and do everything I can to make sure that we play at the level we’re supposed to.”

Marais des Cygnes girls 41, Seabury 17

Things didn’t go much better for the Seahawk girls in Tuesday’s early game.

The Trojans led by 10 after the first quarter and blanked Seabury 9-0 in the second to take a commanding 24-5 halftime lead.

Seabury’s Laura Hoffmann scored a team-best five, while Regan Sisson and Laura Frizell added four each.

“All I can say is that once again our girls played as hard as they could and never gave up, which is something I’m once again very proud about,” Seabury coach Nick Taylor said.

Seabury’s girls team fell to 7-11.
