The same day Sen. Greg Ball officially announced he wouldn’t run for another term in the state Senate, Yorktown Councilman Terrence Murphy announced he would for the seat.

Murphy, a chiropractor, is the owner of the Yorktown Wellness Center, and has three children.

“We need to create an environment where everyone has an opportunity to succeed,” he said in a statement. “How can New Yorkers get ahead while paying the highest property taxes in the country? How can anybody succeed as long as New York is the least business-friendly state in America? As an entrepreneur I know what small business owners are up against every day and its not pretty. As Yorktown Councilman I cut taxes, created jobs, and improved essential services. I will bring that record to Albany and help take New York from worst to first.”

On the Democratic side, Justin Wagner is again competing for the Hudson Valley Senate district.

“I wasn’t running against the Senator, I was running for middle class families in my district,” Wagner said in a statement posted to his Facebook page. “I believe Albany needs to do things differently and I welcome the opportunity to talk about the priorities I share with Hudson Valley voters.”

With Ball leaving, Republicans are now defending as many as three seats including two on Long Island.

Senate Republican Leader Dean Skelos on Thursday said he expects to pick up as many as four seats this election year.

In a statement Friday morning, Skelos acknowledged Ball’s reputation for being something of a maverick in the chamber, adding he expects to retain the seat.

“Greg Ball was outspoken, but he cared deeply about the people he served,” Skelos said. “Greg was committed to public service for all the right reasons, and now he wants to give someone else the same opportunity he had to lead. Since he joined the Senate, I have come to admire and respect Greg Ball, and today I consider him a friend. While he will be greatly missed, I am confident that we will retain this seat and grow our Republican Conference in November.”
