Beau Lofink struck out five batters during his complete-game shutout of the Sioux Falls Brewers, helping Yankton to a 3-0 win on Friday at Cadwell Park in the Class A state amateur baseball tournament.

Gabe Leon and Mitch Gullikson both had two hits for the Tappers, who finished with seven in the win. Yankton’s top-three batters -- Mack Hollingsworth, Leon and Derrik Nelson -- each drove in a run, too.

However, the Tappers were helped by three Brewer errors as two of their runs were unearned. Jeremiah Mauch took the loss, allowing two runs (one earned) and striking out six in his six-inning start. Jose Martinez had two of the Brewers’ three hits.

Yankton advances to the championship game at noon Sunday at Cadwell Park. Sioux Falls plays the winner of Renner and Sioux Falls Squirrels.
