Chief Sealth smothered the Spartans 75-56 in boys basketball late last week at home.
The Seahawks took flight early in the first quarter, and led Bainbridge 19-11 at the start of the second.
Chief Sealth pushed to a 39-21 lead at the half before the Spartans battled back in the second half. The two teams played almost even the rest of the way, with a 20-20 third quarter and 16-15 fourth.
"We struggled in the first half with the speed of the game," noted Spartan Coach Scott Orness.
Chief Sealth forced turnovers and dominated on the boards, and Orness said the Spartans missed a lot of easy buckets and were 4-of-15 inside the paint.
"We made some good adjustments at halftime and we had some players really step up in the second half," he added.
Oskar Dieterich had 16 points and nine rebounds in the second half for Bainbridge and finished with 20 points and 13 boards.
Orness also praised the play of Joey Blacker and Blake Swanson.
"Joey Blacker was aggressive to the basket and Blake Swanson led the way at the point," Orness said.
Blacker finished with 19 points. Fellow Spartan Nick Edens added 13, and Swanson contributed four.
"Even though we lost this Metro League contest, we grew a lot in 32 minutes," Orness added. "The boys made adjustments and saw the results in the second half playing even with a senior-dominated, talented Sealth team."
Bainbridge next faces West Seattle at home Tuesday, Dec. 11. Varsity tip-off is 7 p.m.
