The score was tied in overtime with only a few seconds remaining. The moment was tense but also stunning, considering the Chaska girls basketball team had lost to Eden Prairie by 31 points in December. Now the Hawks had a final shot to upset the No. 1 seed in the Class 4A, Section 2 semifinals March 1.

In the timeout huddle, senior Ella Keenan told a teammate not to even look for her because she figured she would be blanketed by two defenders. But when Eden Prairie switched on a screen, Keenan raced to an opening in the lane.

She grabbed a pass, turned, shot … and touched off a celebration.

“That was such a cool moment for Ella,” Chaska coach Samantha Canter said. “Just with everything that she has gone through.”

Keenan’s journey to that game-winning shot and the Class 4A tournament that starts Wednesday has been marked with setbacks and frustration, countless doctor visits and scary episodes on the court.
