The Grain Valley boys basketball team managed to keep it close until the second quarter.

But the Eagles couldn’t close the gap and fell 70-42 to the Winnetonka Griffins in the first round of its own Grain Valley Eagles Sonic Showdown despite a big game from Cody Sanning.

“We had it down to four in the second quarter,” Eagles coach Andy Herbert said. “They were shooting free throws and got an offensive rebound. By the time we finally got the ball back we were down nine. A lack of focus like that, even for a short time, hurts you. For us to win games like that, we have to be mentally solid the whole time.”

Sanning fired in 25 points and Derreon Parker had eight to lead Grain Valley (6-10).

Winnetonka pulled away to take a 30-15 halftime lead and never looked back. Grain Valley meets Odessa at 6 p.m. Thursday in a consolation game at the Grain Valley Middle School.

LINCOLN PREP 65, OAK GROVE 28: Oak Grove kept it close for one quarter before bowing to Lincoln Prep in the first round of the Grain Valley Eagles Sonic Showdown at Grain Valley Middle School.

“They were a very athletic team and we struggled with their full-court pressure,” Oak Grove coach Jerry Girdner said. “I was proud of our first quarter. We had good execution. In the second half, we just got fatigued by the speed of the game and the turnovers got to us.”

Eric Gant scored nine points to lead the Panthers (4-12), who meet Pleasant Hill, a 63-52 loser to Staley, at 6 p.m. Thursday in a consolation game at Grain Valley Middle School.
