Benson pleaded guilty to aggravated assault and gun possession charges in Cobb County [Georgia] Superior Court.
Benson, 37, who appears on the VH-1 reality series "Baseball Wives," admitted attacking her estranged husband, former major league pitcher Kris Benson, at his Smyrna, Ga., home July 7, in a plea bargain that dropped additional burglary and multiple assault charges, The Atlanta Journal-Constitution said.
Prosecutors said Anna Benson entered her husband's residence holding a metal baton and a handgun, wearing a bulletproof vest and an ammunition belt with a double-edged knife tucked into her waistband, and demanded $30,000.
She smashed a home computer and arresting officers found her smoking a cigarette in the back yard. Kris Benson, who filed for divorce in 2012, ran to a neighbor's house.
Kris Benson pitched for the Pittsburgh Pirates, New York Mets, Baltimore Orioles, Texas Rangers and Arizona Diamondback in an 11-year major-league career that ended in 2010.
As part of her sentence, Anna Benson must successfully complete 90 days of treatment in an out-of-state psychiatric facility and will be prohibited from coming within 500 yards of her husband or threatening him or their three children, the Journal-Constitution said.
The first five years of her probation will be supervised.
