SIOUX FALLS -- Big innings haunted the Mitchell High School softball team in a doubleheader against Yankton on Monday.

The Kernels surrendered more than 10 runs once in the third inning of both outings and it proved to be their undoing. The Gazelles scored 10 runs in the third during Game 1 to turn a 3-0 lead into a 13-0 win in three innings. In Game 2, Yankton then scored 11 in the third to come away with a 12-1 win in five innings.

“The majority of our mistakes were mental,” MHS head coach Craig Krcil said. “We just looked to the wrong base, maybe didn’t make a throw when we should have made a throw. Just a lot of little mental errors. A few things in the outfield, where they outfielder didn’t get a good jump.”

Keirstyn Krcil and Kate Nash were responsible for Mitchell’s two hits in Game 1, while Jacey Linke was 2-for-2 in Game 2. A Barlean drove in the lone run of the day for the Kernels on a ground ball that resulted in a double play.

The Kernels totaled eight hits in two games, but also only had six strikeouts at the plate. Yankton managed to keep Mitchell at bay with off-speed pitches.

“The first pitcher had a really good changeup and kept us off-balance all night long,” Krcil said. “The second pitcher, we were kind of able to get after her a little bit, but (Yankton) made some really good plays on defense that kept us from scratching a few runs across.”

Krcil gave up 13 earned runs on 11 hits and five walks in two innings of work in the circle in Game 1 and Kennedy Wantoch took the loss in Game 2, allowing three earned runs on three hits and eight walks in 2 2/3 innings.

Mitchell (0-6) hosts Sioux Falls Washington in a doubleheader at 6 p.m. Tuesday at Cadwell Sports Complex.
