Kellie Roudabush hit a home run and pitched a three-hit shutout to lead Hilliard Darby High School past Pickerington Central 2-0 in a Division I regional semifinal Thursday at Ohio State.

Darby, which has won 15 of 16 to improve to 20-8, will play Teays Valley in a regional final Saturday at Ohio State. Central finished 23-7.

"You don't feel like an underdog if you believe in yourself," said Darby coach Kevin Moody, whose team lost in a regional semifinal to Grove City 1-0 last season. "Our kids are jelling now. Kellie is hitting her spots. The kids are starting to hit the ball. The defense is stepping up and communicating. Everything is working well for us right now."

Roudabush struck out six and walked two, as Central did not advance a runner past second base.

"We try to focus on staying low and working the inside," Roudabush said. "My movement on my ball is better, and I'm hitting my spots. My changeup worked well today. Normally it doesn't. When I have it and I can change speeds so much, it messes with the batters' heads."

Led by Alivia Nikolaus, who was 3-for-4, the Panthers collected 10 hits. Nikolaus had two singles, a triple and one RBI. Her run-scoring triple drove in the game's first run.

Roudabush added a solo home run in the sixth inning.

"I backed off the plate because I thought the first pitch would be inside," Roudabush said. "She went low and outside the first pitch, then hit me inside on the second pitch. I turned on it."

Central's starter, Kelsey Long, struck out four and walked two as she suffered the complete-game loss.

"It's been our M.O. to come from behind and keep it close enough to make a game of it," Central coach Dan Drees said. "We were right in it. We didn't give up."

Last season, Darby beat Central 1-0 in nine innings in a district semifinal as Roudabush earned the victory.

"We were better prepared for (Roudabush)," Drees said. "We came out and put the ball in play, they made some nice defensive plays."
