PITTSBURGH — Pittsburgh police didn’t dispute Twitter claims by the wife of Cincinnati Reds pitcher Mat Latos that she was punched and had her hair pulled by a fan during the National League wild-card game, but said they consider the matter “closed” and won’t file criminal charges.

Sgt. John Fisher, who headed the 18-officer contingent that augmented stadium security Tuesday, said the incident was “much ado about nothing. What made it big was it involved a pitcher’s wife and it all went on Twitter.”

At a news conference Wednesday, Fisher said stadium security called police to break up an argument involving 20 to 30 Cincinnati and Pirates fans at the Budweiser Bowtie Bar at PNC Park during the Pirates’ 6-2 win Tuesday.

Police didn’t see Dallas Latos being attacked but interviewed her afterward. Latos didn’t have visible injuries and refused medical treatment, Fisher said.
