Chicago ? William Ligue Jr. may well have gone to the ballgame to try to get away from his troubles, which his sister says have become abundant.

But by the time he left Thursday night’s White Sox-Kansas City Royals game at Comiskey Park, Ligue had added to his woes exponentially.

The 34-year-old Alsip man, who took two sons, two nephews and one of their girlfriends out to the ballgame, faces a Saturday bond court hearing after being charged with aggravated battery for charging the field and attacking Royals first-base coach Tom Gamboa.

His 15-year-old son is to appear in Cook County Juvenile Court on Monday, charged with aggravated battery against the coach and aggravated battery against a non-uniformed Illinois state trooper who was providing ballpark security.

Because the ballgame was televised, images of Ligue and his 15-year-old son, both shirtless and pummeling Gamboa, have been shown dozens of times on myriad TV news and sports telecasts nationwide. In most cases the footage also showed father and son being set upon by a swarm of angry Royals rushing to the defense of the 54-year-old coach.

As Ligue’s sister, Kimberly Richardson, watched one of those many replays Friday on her living room TV in Alsip, she felt confused and contrite.

“I have no idea why he would do this,” she said. “I’m so sorry for what my brother did to that man.”

The past year has been hard on her brother, Richardson said, citing a lost job, the death of his month-old daughter in May and a subsequent break-up with his girlfriend.

Richardson would not elaborate, but added, “There’s nothing that excuses this. My mother is so ashamed she won’t even come out of the house.”

Police did not perform toxicology tests on Ligue or his son, nor did their report reflect the father’s possession of a pocket knife clipped to his belt at the time of the incident, saying neither was relevant to the charges against him.

Family members said Ligue had three beers at the game and was not drunk, and that his son was not drinking.

Ligue, who complained of pain in his ribs and arm after being struck by players, was treated and released from St. Anthony Medical Center.
