Most people know Abby Lee Miller for her sharp tongue and award-winning dance instruction.
But on Saturday, the star of Lifetime's "Dance Moms" and "Abby's Ultimate Dance Competition" will try her hand at baseball.
A few minutes before 6:30 p.m., she will throw out the first pitch at Santander Stadium before the York Revolution takes on the Bridgeport Bluefish.
Until 8 p.m., she will sign autographs and take photos with fans along the third-base side of the stadium, said Paul Braverman, promotions and communications manager for the local baseball team.
Because Saturday is dance night at the stadium at 5 Brooks Robinson Way, Miller is a perfect fit, he said.
"Her appearance is a way to help get dance groups out here," Braverman said.
Local dance schools and groups have been invited to perform on the field between innings, but Miller won't be judging them or sternly reminding them to straighten their legs and point their feet.
Tickets are $12 to get inside, see the performances and meet Miller.
Crowd expected: Braverman said he expects the famous dance instructor to draw a large crowd.
"Our theme nights have been very successful. Usually, more than 4,000 show up," he said.
The Revs recently held softball night and hosted popular Olympian Jennie Finch.
Finch helped lead Team USA to a gold medal in the 2004 Summer Olympics and earned a silver medal in the 2008 Summer Olympics.
In May, the team held swim night with Cullen Jones, a swimmer who earned a gold medal and two silver medals in the 2012 Summer Olympics.
About Miller: Miller's collection of medals and trophies have been earned by the elite dance teams for which she serves as head choreographer.
She is the director of Reign Dance Productions, which houses her Abby Lee Dance Company in Pittsburgh.
New episodes of Miller's reality show "Dance Moms" are shown at 9 p.m. Tuesdays on Lifetime.
The show offers a behind-the-scenes look at Miller's competitive dance teams and team members' mothers, who often disagree with each other and their daughters' tough teacher.
In "Abby's Ultimate Dance Competition," Miller serves as a judge on a show that seeks the top talent among several dancers who have won national titles.
Her fellow judges are Richy Jackson, the visual director and choreographer for Lady Gaga, and Rachelle Rak, a Broadway star. The third season will begin this fall.
The winner of the show gets a $100,000 prize and scholarship to the Joffrey Ballet School in New York.
Both shows have produced high ratings and a strong following on social media.
"Dance night is the last theme night of the season, and we're expecting it to be a good one," Braverman said.
