THE DUCK POND – When the Northwoods League playoffs open next Sunday, the Madison Mallards almost certainly will be facing the Wisconsin Woodchucks.

The teams offered an intriguing preview of the potential best-of-three series Sunday before 3,753 at Warner Park, with the Woodchucks prevailing 6-5 on an unearned run in the 12th inning.

Pete Wiedewitsch’s fielder’s choice that scored Kyle Bohm with the go-ahead run.

Wisconsin (38-19 overall, 28-5 second half) clinched at least a share of the South Division second-half title.

The Woodchucks are likely to earn home-field advantage due to a better overall record, meaning the Mallards (33-24, 11-14) would host Game 2, on Monday, August 11.
