GROTON – Colby Dunker delivered a one-out single to center to plate the winning run in the bottom of the seventh inning as Groton walked off Warner-Ipswich-Northwestern 9-8 in high school baseball action Sunday afternoon.

Groton had taken a 2-0 lead on RBI singles by Nick Morris in the second and Logan Ringgenberg in the third. That’s when W-I-N scored eight unanswered runs to jump in front.

A pair of errors led to a run in the top of the third, and then the visitors had five hits and four walks in a seven-run fourth inning. Lincoln Kroll, Devon Fischbach, Alec Mikkelsen, Dawson Ward and Chays Mansfield each drove in a run to highlight the frame.

Groton responded with five runs in the bottom of the fifth, two on Jarrett Erdmann’s triple and another on a Brevin Fliehs single, and then tied the game at 8-8 in the sixth on Carter Simon’s RBI single. That set the stage for the bottom of the seventh.

Dunker finished with three hits to lead Groton, while Fliehs and Simon each had a pair.

A total of six different players each had a single for W-I-N.
