The game was an emotional roller coaster for both head coaches who were as physically and emotionally drained as their players by game's end.
The contest featured 20 lead changes, 17 ties, saw three players foul out and came within a whisker of going to a fifth overtime.
"We didn't make enough plays to win," said Pierce City coach Matt Street. "We have got to get tougher on the boards and cut off our opponents' second chance attempts."
Six points was the largest lead either team could muster during the game's grind. The Eagles held a 9-3 edge early in the first and the Tigers briefly grabbed a 36-30 edge in the third period.
Pierce City's Zack Hyde sank two free throws with 1:20 left in regulation and both teams squandered opportunities to take a lead in the closing seconds to force the overtime madness.
The teams traded 2-point leads during the first two extra sessions.
The Eagles appeared to be in good shape when Cedric O'Hara hit a 15-foot jump shot from the left wing to give the green and white a 69-65 edge with 2:28 left in the third overtime. However, Stockton's Tanner Collins countered with an old fashioned 3-point play to cut the gap to 1 point.
The fourth extra frame saw Stockton take a 3-point lead (78-75) with 33 seconds remaining.
Cody Fitchpartick's bucket with 15 ticks left drew the Eagles closer. A quick foul sent Stockton's Colby Walker to the charity stripe with 13 seconds left. Walker missed his first shot and hit his second.
The Eagles quickly moved the ball up court but missed a point-blank layup up to force another overtime.
Scoring for Pierce City: Fitchpatrick and Hyde, 22 each; O'Hara, 21; and Colton Drollinger and Kole Kelley, 6 apiece.
